If the battery is 4.0V the voltmeter reading across R is 2.0V and the resistance per unit length of wire AX is 2 ohms per metre calculate the current in the circuit when AP is 40.0cm(neglect the internal resistance of the battery)

- The resistance of the first resistor (R₁) is 12 Ω.

- The electromotive force (EMF) of the battery is 18 V.

- The internal resistance of the battery is 12 Ω.

To solve the given problem, we can apply Kirchhoff's laws and Ohm's law to determine the resistance of the first resistor (R₁) and the electromotive force (EMF) and internal resistance of the battery.

Let's start by calculating the resistance of the first resistor (R₁):

1. Apply Ohm's law to find the voltage drop across the external circuit:

  V = I * R

  V = 1 A * 6 Ω

  V = 6 V

2. The voltage drop across the external circuit is equal to the EMF minus the voltage drop across the internal resistance of the battery:

  V = E - Ir

  6 V = E - (1 A * r)   (where r is the internal resistance of the battery)

3. We also know that the EMF of the battery is the sum of the voltage drops across each cell in the battery:

  E = 6 cells * 3 V/cell

  E = 18 V

4. Substitute the value of E in the equation from step 2:

  6 V = 18 V - r

  r = 12 Ω

Therefore, the resistance of the first resistor (R₁) is 12 Ω.

The bird remains at rest for 3.0 seconds, so its velocity is 0 m/s and displacement is also 0 m.

What is velocity?

To create the graphs, we need to first calculate the bird's motion parameters:

Initial velocity, u = 0 m/s

Final velocity, v = 4.0 m/s [E]

Time taken, t = 8.0 s

Acceleration, a = (v - u) / t = (4.0 - 0) / 8.0 = 0.5 m/s²

Displacement, d = ut + (1/2)at² = 0 + (1/2)(0.5)(8.0)² = 16.0 m

After this, the bird remains at rest for 3.0 seconds, so its velocity is 0 m/s and displacement is also 0 m.

Then, the bird starts moving again with a velocity of 3.0 m/s [W] and takes 5.0 seconds to reach this velocity. Therefore, its acceleration is:

Initial velocity, u = 0 m/s

Final velocity, v = 3.0 m/s [W]

Time taken, t = 5.0 s

Acceleration, a = (v - u) / t = (3.0 - 0) / 5.0 = 0.6 m/s²

Displacement, d = ut + (1/2)at² = 0 + (1/2)(0.6)(5.0)² = 7.5 m [W]

Using this information, we can create the required graphs:

These graphs are shown in below image.

A Position-time graph shows that the bird starts from the nest, moves 16.0 m to the east, remains there for 3.0 s, and then moves 7.5 m to the west.

The Velocity-time graph shows that the bird starts from rest, reaches a velocity of 4.0 m/s [E] in 8.0 s, remains at rest for 3.0 s, and then reaches a velocity of 3.0 m/s [W] in 5.0 s.

An Acceleration-time graph shows that the bird has an acceleration of 0.5 m/s² [E] from 0 to 8.0 s, no acceleration from 8.0 to 11.0 s (remains at rest), and an acceleration of 0.6 m/s² [W] from 11.0 to 16.0 s.

A theory for suing for damages caused by products is breach of warranty. This is a contract claim, and the purchaser of the product is claiming that the product failed to perform as warranted.

The ball needs to go at least  speed is 13 m/s per second to be able to clear the ceiling.

angle should you toss the ball 46.26°.

From the query, we learn that

We are 6.0 metres away from one home wall.

who is 6.0 metres from the wall across from you.

Both the throw and the catch take place one metre above the ground.

Assume that you and your companion are both 6.0 metres from the edge of the roof.

The Newtons equation for the distance is typically expressed numerically as

\(s=v*t+\frac{a}{2}*t^{2}\\5=0*t+4.9*t^{2}\\t=1.04\)

Therefore

\(2*t = 2.0s\)

Where

\(18=V_{x} *2.0\\V_{x} =8.9\)

And

\(5=V_{y} *1.04-4.9*1.04^{2}\\V_{y} =9.8\)

Therefore

\(V=\sqrt{V_{y}^{2}+V_{x} ^{2} } \\V=\sqrt{(9.8)^{2}+(8.9)^{2}} \\\V=13m/s\)

In order to determine the angle at which you should toss the ball, you must first calculate the distance between you and your friend. This is done by using the Pythagorean Theorem to calculate the hypotenuse of the right triangle formed by the two walls and the distance between you and your friend:

\(C = \sqrt (6.0m)^2 + (6.0m)^2 \\ = 8.485m\)

Now you can calculate the angle using trigonometry. Since the triangle is a right triangle, you can use the inverse tangent function to calculate the angle:

tan⁻¹\((\frac{6.0m}{8.485m})\) = 46.26°

Therefore, you should toss the ball at an angle of 46.26°.

On the apple, we apply "antigravitational force."

The apple exerts "gravitational force" on us.

The gravitational attraction, an attractive force whose magnitude is directly proportional to the masses of the two objects and inversely proportional to the square of their distance from one another, draws all mass-containing things together.

You can never decrease the gravitational pull produced by adding mass. It is possible for gravitational forces acting in opposition to one another to cancel one another out and leave no net force. It would be conceivable for gravity to push objects instead of always dragging them if it weren't always additive.

A place or thing being free from the pull of gravity is the goal of the hypothetical phenomena known as anti-gravity. It doesn't mean balancing the force of gravity with another force, like electromagnetism or aerodynamic lift, or the lack of weight under gravity felt in free fall or orbit.

Answer:

From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.

Explanation:

As the Earth you’re living on spins once, the area in which you live moves into the light coming from the Sun (DAY), spins on and eventually moves out of the Sun’s light (NIGHT).

"But...I swear I can see the sun moving across the sky!"

Yes, it really appears that way, doesn’t it?  Kinda explains why, for centuries of human existence, we believed that the Earth was in the centre of the solar system and the Sun moved around us.  Now we know better; it’s the Sun at the centre, and the Earth and other planets orbit around the Sun. So that means we have to think a bit harder about why there’s Night and Day, and why it seems that it’s the Sun doing the moving.

In terms of physics, sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave. Sound is the receipt of these waves and the brain's perception of them in terms of human physiology and psychology. Only acoustic waves with frequencies between about 20 Hz and 20 kHz, or the audio frequency range, may cause a human to have an auditory sensation. These correspond to sound waves in air with an atmospheric pressure of 17 metres (56 ft) to 1.7 centimetres (0.67 in) in wavelength. Ultrasounds are sound waves with a frequency higher than 20 kHz that are inaudible to humans. Infrasound refers to sound frequencies below 20 Hz.

Renewable energy is useful energy that is collected from renewable resources, which are naturally replenished on a human timescale. A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.

Answer:

We are given:

m1 = 500 kg             m2 = 1500 kg

v1(initial) = x m/s       v2(initial) = 0 m/s

v1(final) = 20 m/s      v2(final) = 20m/s

According the the law of conservation of momentum:

m1v1(initial) + m2v2(initial) = m1v1(final) + m2v2(final)

Plugging the values in this formula:

(500*x) + (1500 * 0) = (500 * 20) + (1500 * 20)

500x = 20(1500 + 500)

500x = 20(2000)

x = 20 * 4

x = 80 m/s

Therefore, the car was initially moving at a velocity of 80 m/s

Answer:

(A)  the acceleration  experienced by the proton 2.821 x 10¹² m/s²

(B) the speed of the proton is 2.67 x 10⁵ m/s

Explanation:

Given;

electric field experienced by the proton, E = 2.95 x 10⁴ N/C

charge of proton, Q = 1.6 x 10⁻¹⁹ C

mass of proton, m = 1.673 x 10⁻²⁷ kg

distance moved by the proton, d = 1.26 cm = 0.0126 m

(a)

The force experienced by the proton is calculated as;

F = ma = EQ

where;

a is the acceleration  experienced by the proton

\(a = \frac{EQ}{m} \\\\a = \frac{2.95\times 10^4 \ \times \ 1.6\times 10^{-19}}{1.673 \times 10^{-27}} \\\\a = 2.821 \times 10^{12} \ m/s^2\)

(b) the speed of the proton is calculated;

v² = u² + 2ad

v² = 0 + (2 x 2.821 x 10¹² x 0.0126)

v² = 7.109 x 10¹⁰

v = √7.109 x 10¹⁰

v = 2.67 x 10⁵ m/s

The positively charged particle will move towards the negatively charged particle.

Explanation:

According to Coulomb's Law, there are two types of charges--positive charge and negative charge. Coulomb said that they are either attractive or repulsive but the basic law in charges states that opposite attracts. Since they (the two charged objects) are oppositely charged, they will then move towards one another.
