Elephant and the eath because Fg is determined by Mass of an object.. So elephant has greater mass therefore, it's Fg is higher

According the universal  law of gravitation, the gravitational force is directly proportional to the mass of an object.  An elephant weighs so much than a man and thus it will experience larger gravitational force from earth.

Gravitational force is a resistive force by which an object attracts other objects towards its centre of mass. The force exerted by the object depends on the mass and the force experienced by the other object depends on its mass and distance between the two objects.

According to universal law of gravitation, the gravitational force is directly proportional to the mass of the object and distance from the ground. The expression for the law is written as:

\(\rm g = G \frac{M_{1} M_{2}}{r^{2}}\)

Where, G is the universal gravitational constant and M1 and M2 be the masses of two objects which and r be the distance between them. As per this relation gravity decreases with increase in distance and increase with an increase in mass.

Therefore, a massive body such as an elephant will experience greater gravitational force from the earth.

Answer:

Interpolation gives more accurate data or points compared to extrapolation.

Interpolation can be a little easier than extrapolation.

Interpolation does not require one to extend the already existing data points, where extrapolation requires elaboration of the pattern, curve, or line.

Extrapolation:

This is a statistical method used to predict unknown values for points outside the range of the recorded data. It is used to extend a known sequence of values beyond the sampled area

Extrapolation: with Extrapolation, we can be less confident with the unknown values derived using this method. The method includes values from outside the sampled area, which makes the predictions diverge away from the true values. In curve fitting, this method is not preferred.

Extrapolation:

the ability to retrieve negative answers is one characteristic that makes it unique for interpolation. This statistical method allows one to extend the values in the range either forward or backward. This technique of extending values is responsible for attaining the negative values.

Explanation:

Balancing equations is the process of ensuring that the number of atoms of each element is the same on both sides of a chemical equation. This is done by adjusting the coefficients (numbers in front of the chemical formulas) to achieve balance. The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction.

When a chemical reaction occurs, the atoms of the reactants rearrange to form new compounds, known as the products. The law of conservation of mass states that the total mass of the reactants must be equal to the total mass of the products. This means that the number of atoms of each element must be the same on both sides of the equation.

To balance an equation, you need to adjust the coefficients in front of the chemical formulas. You can change the coefficients, but not the subscripts within the formulas, as this would change the identity of the compounds. By adding coefficients, you ensure that the number of atoms of each element is the same on both sides of the equation.

For example, let's consider the equation:

2H₂ + O₂ → 2H₂O

In this equation, we have 2 hydrogen (H) atoms on the left side, but only 2 hydrogen atoms on the right side. To balance the equation, we add a coefficient of 2 in front of the H₂O on the right side, resulting in:

2H₂ + O₂ → 4H₂O

Now we have 4 hydrogen atoms on both sides, fulfilling the law of conservation of mass.

In summary, balancing equations ensures that the number of atoms of each element is the same on both sides of the equation, in accordance with the law of conservation of mass. This is achieved by adjusting the coefficients in front of the chemical formulas.

The product among alcohol, gasoline, travel souvenirs, cigarettes that will have elastic demand is cigarettes.

Elastic demand refers to a situation in which a change in the price of a good or service results in a more significant change in the amount demanded. When the percentage change in quantity demanded is greater than the percentage change in price, the demand for the product is said to be elastic.

When the quantity demanded of a product decreases significantly when the price rises, the demand for the product is said to be elastic. Similarly, when a slight change in price causes a significant change in quantity demanded, the demand is said to be elastic. Conversely, if a product's price increases by a small percentage, and the demand for the product decreases by a smaller percentage, the demand for the product is said to be inelastic.

Cigarettes, of all the products listed above, are likely to have an elastic demand.

This is because smokers who are addicted to cigarettes are more likely to quit smoking or reduce their consumption in response to an increase in the price of cigarettes compared to the other goods.

Thus, a slight increase in the price of cigarettes is likely to cause a significant decrease in the number of cigarettes consumed.

Energy stored in a solenoid per unit volume = B₀² / (2μ₀)

B₀= μ₀ n I₀

n is no of turns per unit length .

Energy stored in a solenoid per unit volume = ( μ₀ n I₀)² / (2μ₀)

=μ₀n²I₀²/2

n = 40 turns / cm = 40 x 100 turns per meter.

I₀ = 5000A .

Putting the values

Energy stored in a solenoid per unit volume

= 4π x 10⁻⁷ x 40 x 10² x 5000² /2

= 1256 J/ m³

Volume of solenoid = cross sectional area  x length

= 28 x 10⁻⁴ x .10 = 2.8 x 10⁻⁴ m³

Total energy stored = 1256  J / m³ x 2.8 x 10⁻⁴ m³

let's calculate

         I = \(\frac{1}{12}\)  2  4²

         I = 2.667 kg m²

In a conventional current flow model, current is considered as the flow of positive charges. According to this model, the direction of current is defined as the direction in which positive charges would flow.

In reality, however, the actual flow of charges is due to the movement of negatively charged electrons.

In a closed circuit, the conventional current flows from the positive terminal of the power source (such as a battery) towards the negative terminal. This convention was established before the discovery of the electron's negative charge. The positive charges, which are typically attributed to protons in the atoms, are considered to move in the opposite direction to the actual flow of electrons.

So, if we were to observe a circuit from the perspective of conventional current flow, the current would be flowing from the positive terminal to the negative terminal of the power source. This convention helps establish a consistent reference for understanding and analyzing electrical circuits, even though it contradicts the actual movement of electrons.

Assuming that the night will remain clear, calm, and unsaturated, the predicted minimum temperature is 32°f. suddenly, the wind speed increases and remains gusty throughout the night. The minimum temperature will most likely be higher than predicted due to mixing.

As wind speed increases, it moves the air molecules at a greater frequency due to collisions, and hence, the overall kinetic energy of the molecules increases making them move at a higher speed.

When the night is calm and clear then the surface of earth will be cooler than usual as the air molecules move at normal speed. However, when the wind speed increases, it draws warmer air from the surrounding which is mixed downward on the earth's surface preventing the temperature from dropping. Therefore, on a such night, the temperature will be slightly warmer than usual.

The initial speed of the car with a length of the skid mark of about 64 m long and kinetic friction of 0.70 is 29.63 m/s.

A force that acts between moving surfaces is referred to as kinetic or sliding friction. It is the frictional force that prevents relative motion between surfaces in contact. The formula to calculate this kind of friction is, \(f _k =\mu_kN\) where uk is the coefficient of friction and N is the normal force.

Given the length of the skid mark (Δd) is 64 m and the coefficient of kinetic friction is 0.70. The final velocity vf is 0 because the car stops.

Let us assume the initial velocity vi, mass m,  and deceleration a. Then, the normal force acting on the car is N = mg. The kinetic friction will be,

\(f _k =\mu_kN\\f_k=\mu_kmg\)

Let's assume the only force acting on the system is kinetic friction, then friction force=ma. Solve this equation with the above equation,

\(\begin{aligned}ma&=\mu_kmg\\a&=\mu_kg\end{aligned}\)

Then, the initial speed is calculated as follows

\(\begin{aligned}v_f^2&=v_i^2-2a\Delta d\\0&=v_i^2-2\mu_kg\Delta d\\v_i^2&=\mathrm{2\times0.70\times9.80\;m/s^2\times64\;m}\\v_i^2&=\mathrm{878.08\;m^2/s^2}\\v_i&=\mathrm{29.63\;m/s}\end{aligned}\)

Explanation:

The dart moves when it leaves the spring gun with a velocity of 22.4 m/s.

Potential energy is defined as the stored energy that depends on the relative position of different parts of a system such as springs have more potential energy when it will be compressed or stretched.

For velocity calculation of the dart when it leaves the spring gun, using the formula for potential energy stored in a spring:

\(PE = (1/2)kx^2\)

where,

k is the spring constant

x is the compression of the spring.

Since the spring is compressed by 5 cm, the potential energy stored in it is:

\(PE = (1/2)(250 N/m)(0.05 m)^2\)

PE = 6.25 J

The potential energy stored in the spring will be transferred to the dart when it is released which can be calculated from the velocity of the dart using the equation of conservation of energy:

\(PE = (1/2)mv^2\)

where,

m is the mass of the dart

v is its velocity.

Solving for v:

v = sqrt(2PE/m)

=> sqrt(2(6.25 J)/(0.025 kg))

=> 22.4 m/s.

Thus, the dart moves when it leaves the spring gun with a velocity of 22.4 m/s.

The S.I. unit of E is NC^-1 and that of B is NA^-1 m^-1, then unit of E/B is A m/C (ampere meter per coulomb). This unit represents the ratio between the electric field and the magnetic field, indicating the strength and direction of the electromagnetic field.

The SI unit of electric field (E) is NC^(-1) (newton per coulomb) and the SI unit of magnetic field (B) is NA^(-1) m^(-1) (tesla). To determine the unit of E/B, we need to divide the unit of E by the unit of B.

Dividing the unit of E (NC^(-1)) by the unit of B (NA^(-1) m^(-1)), we can simplify the expression:

E/B = (NC^(-1))/(NA^(-1) m^(-1))

To simplify this expression, we can cancel out the common units in the numerator and denominator:

E/B = (N/C)/(N/(A m))

Now, let's simplify further by dividing the numerator and denominator:

The image is approximately 9.33 cm away from the mirror, on the object's side.

To determine the image location formed by a converging mirror, we can use the mirror equation:

1/f = 1/d_o + 1/d_i

where:

f is the focal length of the mirror,

d_o is the object distance (distance of the object from the mirror), and

d_i is the image distance (distance of the image from the mirror).

In this case, the focal length (f) is given as 7 cm, and the object distance (d_o) is 4 cm.

Plugging in the values into the mirror equation:

1/7 = 1/4 + 1/d_i

To find the image distance (d_i), we can solve for it:

1/d_i = 1/7 - 1/4

1/d_i = (4 - 7) / (4 * 7)

1/d_i = -3 / 28

Taking the reciprocal of both sides:

d_i = 28 / -3

d_i ≈ -9.33 cm

The negative sign indicates that the image formed by the converging mirror is virtual and located on the same side as the object.

Answer:

Initial velocity, u = 23.33 m/s

Explanation:

Given the following data;

Acceleration = 2.5 m/s²

Distance = 4 km to meters = 4000 meters

Time = 0.8 mins to seconds = 0.8 * 60 = 48 seconds.

To find the initial velocity, we would use the second equation of motion;

\( S = ut + \frac {1}{2}at^{2}\)

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

4000 = u*48 + ½*2.5*48²

4000 = 48u + 1.25*2304

4000 = 48u + 2880

48u = 4000 - 2880

48u = 1120

Initial velocity, u = 1120/48

Initial velocity, u = 23.33 m/s
