Answer:

speed are different at different places

Explanation:

because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other

a) Electric field lines radiate outward from the positive charge, and equipotential lines are concentric circles around the charge.

b) The force between the test charge and the source charge is 5.4 N.

c) The change in potential energy would be negative if the test charge is moved closer to the source charge.

a) To draw the electric field around a +3.0 × \(10^-^5\) C point source charge, we can use the principle that electric field lines radiate outward from positive charges. The density of field lines represents the strength of the electric field. Here is a visual representation:

```

  +  

  |

  |  

---+---

  |  

  |  

```

The "+" symbol represents the positive point source charge, and the lines radiating outward represent the electric field lines. The direction of the field lines is away from the positive charge, indicating the direction of the electric field.

For the equipotential lines, we can draw two concentric circles around the point charge. The distance between the circles represents a constant potential difference.

```

|    |  

|    |  

|    |  

 ---  

```

b) To calculate the force between the +6 µC test point charge and the +3.0 × 10–5 C source charge, we can use Coulomb's Law:

\(\[ F = \frac{{k \cdot q_1 \cdot q_2}}{{r^2}} \]\)

where F is the force, k is the electrostatic constant (approximately 9 × 10^9 N·m^2/C^2), q1 and q2 are the charges, and r is the distance between the charges.

Substituting the given values:

\(\[ F = \frac{{(9 \times 10^9 \, \text{N} \cdot \text{m}^2/\text{C}^2) \cdot (6 \times 10^{-6} \, \text{C}) \cdot (3 \times 10^{-5} \, \text{C})}}{{(0.03 \, \text{m})^2}} \]\)

Simplifying the equation:

\(\[ F = 5.4 \, \text{N} \]\)

Therefore, the force between the test charge and the source charge at a distance of 3.00 cm is 5.4 N.

c) If the test charge were moved closer to the source charge, the change in its potential energy would be negative. This is because the potential energy of a test charge in the presence of an electric field is given by the equation:

\(\[ U = q \cdot V \]\)

where U is the potential energy, q is the charge, and V is the electric potential. As the test charge approaches the source charge, the electric potential increases due to the increased influence of the source charge. Since the test charge is positive, a decrease in potential energy corresponds to a negative change.

Answer: 5.7

Explanation: 38% of 15.

The weight we experience ourselves and the ability to stand in the ground is due to the gravitational pull of earth. If this pull is lower we feel weight loss. So the cat will have a weight of 5.7 pounds or 2.58 kg in mars where the gravitation is about 38% of earth.

Gravitational force is a kind force by which a body attracts other objects into its centre of mass. Earth have strong gravitational effect on objects and thus we are all standing on the surface and everything falling from a height hits the ground.

As the mass of the object increases, gravitational effect also increases. The weight experienced by a body is the product of its mass and gravity. Thus massive body have greater weight.

Our mass is constant everywhere but weight will change according a change in gravity. Mars  have only 38% of gravity of earth. Thus the cat weighing 15 pounds on earth will loss its weight in mars by 38%.

Thus, 15 × 38/100= 5.7 pounds will be the weight of the cat in mars.

The rate of temperature change is not constant over time due to several factors, such as the Earth's climate system and its various components, the energy that gets exchanged with the atmosphere, and the natural processes of the Earth.
What is tempreture?
Temperature is a measure of the warmth or coldness of an object or environment. It is measured by thermometers using a variety of scales such as Celsius, Fahrenheit, and Kelvin. Temperature can affect a variety of physical and chemical processes, and is a crucial element in climate and weather systems. Temperature is also an important factor in determining the rate of metabolism in all living organisms.
The Earth's climate system is a complex system made up of many components, such as the atmosphere, oceans, and land. These components interact with each other and with the energy from the sun, which affects the Earth's climate. This energy exchange influences the Earth's temperature, which can cause changes in the rate of temperature change.
Natural processes of the Earth, such as the Milankovitch cycles, also affect the rate of temperature change. The Milankovitch cycles are the periodic changes in the Earth's orbital parameters, such as its eccentricity, obliquity, and precession. These periodic changes in the Earth's orbit can cause changes in the amount of energy that gets absorbed by the Earth, which affects the rate of temperature change.
In addition, human activities can also affect the rate of temperature change. For instance, various forms of pollution, such as carbon dioxide and other greenhouse gases, can trap heat in the atmosphere and cause the Earth's temperature to increase. This can lead to higher rates.

The magnitude of the magnetic flux through each turn of the coil at the instant when the current is 3.60 A is 3.72×10⁻⁶ Wb.

The quantity of magnetic field traveling through a specific region or surface is measured by magnetic flux. It is described as the result of the area that the magnetic field travels through and its magnitude, where the area is perpendicular to the field's direction. The Weber is the magnetic flux SI unit (Wb)

Given that,

EMF = 18.0 mV = 0.018 V

In the peak of summer, it hasn't rained in a week, and the plants are looking rough, so watering the plants for an hour is a good idea.

However, the next day, you come back to the garden, and the plants look in worse shape than they did previously, as if none of that water made it to the plant. Plants absorb water through their roots. The root system of a plant is responsible for drawing water and nutrients from the soil. A plant's root system must be able to absorb water quickly in order for the plant to grow and thrive. When the soil around the root system is dry, the roots will stop growing and will not be able to absorb water.

It may even start to die. Watering plants during the peak of summer is important because it will help keep the soil moist and prevent the roots from drying out. However, watering a plant too much can be harmful. If a plant is overwatered, the water may not be able to penetrate the soil and reach the roots. Instead, it may just sit on top of the soil, causing the roots to rot and die. This can cause the plant to wilt and die.To summarize, if the soil around the plant is too dry, the roots may not be able to absorb the water you gave them, causing the plant to look worse than before. Conversely, overwatering can also be harmful because the water may not be able to penetrate the soil and reach the roots, causing the roots to rot and die.

The amount of helium atoms lined up side to side that  would span the diameter of a human hair is: 1.5625*10^6  atoms

To solve this problem the we have to do the conversion of units with the given information.

Information about the problem:

By converting the units of the helium atom's diameter from nm to mm, we have:

d(helium atom)= 0.064 nm * 1 m/1*10^6 mm

d(helium atom)=  6.4*10^-8 mm

To know how many helium atoms lined up side to side would span the diameter of a human hair, we have to do a division as a following:

amount of helium atoms lined up side to side= d(human hair)/d(helium atom)

amount of helium atoms lined up side to side= 0.1 mm/6.4*10^-8 mm

amount of helium atoms lined up side to side= 0.1 mm/6.4*10^-8 mm

correct me if I am wrong

Answer:

a. 1.062 × 10⁻⁹ C/m² b. 5.472 × 10⁵ C c. 7.685 × 10⁹ V d. -210.12 V e. 4.972 × 10³ N f. F the electric force is much less than the gravitational force F₁ of the earth on the moon.

Explanation:

a. The surface charge density D = ε₀E where E = 120 N/C

D = ε₀E = 8.854 × 10⁻¹² F/m × 120 N/C = 1.062 × 10⁻⁹ C/m²

The charge density is positive since the electric field is positive or directed downwards. Only a positive charge could direct an electric field out of itself.

b. Since the surface charge density is uniform over the planet and charge, Q = DA where A = area of earth = 4πr² where r = radius of earth = 6.4 × 10⁶ m.

So Q = DA

= 1.063 × 10⁻⁹ C/m² × 4π × (6.4 × 10⁶ m)²

= 5.4715 × 10⁵ C

≅ 5.472 × 10⁵ C

c. The earth's electric potential due  to this charge Q is V = Q/4πε₀r

= 5.472 × 10⁵ C ÷ (4π × 8.854 × 10⁻¹² F/m × 6.4 × 10⁶ m)

= 5.472 × 10⁵ C ÷ 712.081 × 10⁻⁶ F

= 0.07685 × 10¹¹ V

= 7.685 × 10⁹ V

= 7.685 GV

d. Since V = Q/4πε₀r, and we are going to be dealing with a small change in length compared to r, we differentiate V to get the differential change in potential.

So, dV/dr = -Q/4πε₀r²

dV = -Qdr/4πε₀r² ,dr = 1.75 m

dV = -5.472 × 10⁵ C × 1.75 m ÷ [4π × 8.854 × 10⁻¹² F/m × (6.4 × 10⁶ m)²]

dV = -9.576 × 10⁵ Cm ÷ 4557.318 Fm

dV = -210.124 V

dV ≅ -210.12 V

e. Let Q₁ = charge on moon and Q₂ = charge on earth. Given that Q₁ = 0.273Q₂, the force of attraction between earth and moon is F = Q₁Q₂/4πε₀R² where R = distance between earth and moon = 3.844 × 10⁸ m

F = Q₁Q₂/4πε₀R²  

= 0.273Q²/4πε₀R²

= 0.273 × (5.472 × 10⁵ C)²/ [4π × 8.854 × 10⁻¹² F/m × (3.844 × 10⁸ m)²]

= 8.1744 × 10¹⁰ C²/1644.054 Fm × 10⁴

= 0.004972 × 10⁶ N

= 4.972 × 10³ N

= 4.972 kN

f. The gravitational force between earth and moon F₁ = Gm₁m₂/R² where m₁ = mass of moon = 7.3 × 10²² kg and m₂ = mass of earth = 5.97 × 10²⁴ kg.

F₁ = 6.67 × 10⁻¹¹ Nm²/kg² × 5.97 × 10²⁴ kg × 7.3 × 10²² kg/(3.844 × 10⁸ m)²

= 290.685 × 10³⁵ Nm²/14.776 × 10¹⁶ m²

= 19.67 × 10¹⁹ N

= 1.967 × 10²⁰ N

≅ 2 × 10²⁰ N

Since F₁/F = 1.967 × 10²⁰ N/4.972 × 10³ N = 3.95 × 10¹⁶ ≅ 4 × 10¹⁶.

F the electric force is much less than the gravitational force F₁ of the earth on the moon.

(a) Time = 9.30 seconds. (b) Average Speed is 48.2 m/s. (c) Displacement is 305 m. (d) If the calculations are accurate, the time, speed, and distance values found in part (d) should match those found in parts (a), (b), and (c).

To determine the answers to parts (a) through (c) of the problem if the officer starts accelerating 1.00 s after the car passes him,

(a) Time: Since the car continues to move at a constant speed, its time to cover the 400 m distance remains the same as in part (a), i.e., 9.30 s.

(b) Speed: The officer now starts accelerating 1.00 s after the car passes him, so his time to cover the 400 m distance is 1.00 s less than the car, which is 8.30 s. Therefore, his average speed would be:

v = d/t = 400 m / 8.30 s = 48.2 m/s

(c) The displacement of the officer would be the same as in part (c), i.e., 305 m.

To determine the time it takes the officer to catch the car, we can use the same approach as in part (b) but consider the relative velocity between the car and the officer, v_rel = v_car - v_officer.

At the moment the officer starts accelerating, the car has already covered a distance of, d_car = v_car × t_acceleration where t_acceleration is the time the officer takes to start accelerating after the car passes him. Therefore, the displacement is,

d_initial = d_car - d_officer = v_car × t_acceleration - 0

where d_officer is the initial distance between the officer and the car.

Then, the time it takes for the officer to catch the car is, t_catch = d_initial / v_rel.

To determine the speed of the officer when he catches the car, we can use the same approach as in part (b), but use the time it takes for the officer to catch the car, i.e., t_catch. Therefore, the speed of the officer would be, v = d / t_catch = 400 m / (t_catch + 1 s). To determine the distance the officer travels before catching the car, we can use the same approach as in part (c), but use the time it takes for the officer to catch the car, i.e., t_catch. Therefore, the distance the officer travels would be, d = v × t_catch. The values obtained for the time, speed, and distance in part (d) should be the same as in parts (a), (b), and (c) if the calculations are correct.
