Answer:

The potential difference between points A and B can be calculated using the equation V = W/Q, where V is the potential difference, W is the work done, and Q is the charge. In this case, W = 66 J and Q = 19.2 μC. Therefore, the potential difference is:

V = 66 J / 19.2 μC = 3.44 V.

The speed of an object under the influence of gravity can be found using the equation v = v0 + a * t, So the speed of the ball one second later would be 24.8 m/s.

where v is the final speed, v0 is the initial speed, a is the acceleration due to gravity (9.8 m/s^2 downward), and t is the time elapsed.

In this case, the initial speed is 15 m/s (vertically downward),

the acceleration due to gravity is 9.8 m/s^2 downward, and the time elapsed is 1 second, so:

v = 15 m/s + 9.8 m/s^2 * 1 s

= 24.8 m/s

Speed is a scalar quantity which tells how fast an object is moving, regardless of its direction.

(a) If you double your driving speed,  time required to come to a stop will be halved (b) the distance needed to stop will be quadrupled.

Deceleration is defined as a decrease in velocity. Deceleration is slowing down. Negative acceleration is acceleration in the negative direction in the coordinate system. Negative acceleration may/ may not be deceleration and deceleration may /may not be negative acceleration.

If the brakes in a car create a constant deceleration, then time required to come to a stop is directly proportional to velocity, while the distance needed to stop is proportional to square of the velocity. So, if you double your driving speed, the time required to come to a stop will be halved, while the distance needed to stop will be quadrupled.

The resultant force on the car with mass 1200kg required to produce an acceleration of 0.8m/s squared is  960 N

A resultant force is the total amount of force that is created as a result of multiple forces acting on an object. It is calculated by adding up all of the individual forces acting on the object. The resultant force can be used to calculate the acceleration of the object, as it is equal to the mass of the object multiplied by its acceleration.

By understanding the resultant force, the direction and magnitude of the forces necessary to produce a desired effect could be determined. This is particularly useful in engineering and physics, where knowing the forces involved in a situation can help us understand the dynamics of a system.

200 Joules is work done moving the box if a large box is pushed 10 meters across a horizontal floor with a force of 20 n.

The work done on an object can be calculated as the force applied on the object multiplied by the distance it moves in the direction of the force. In this case, the force applied on the box is 20 N and it is moved 10 meters, so the work done can be calculated as:

W = F * d

W = 20 N * 10 m

W = 200 J (Joules)

So, 200 Joules of work is done in moving the box 10 meters with a force of 20 N.

A cylinder is measured to have

Find its density in kg/m³!

The radius of the cylinder is

r = ½d

r = ½(3.5)

r = 1.75 inches

r = 1.75 × 2.54 cm

r = 4.4 cm

We find the volume of the cylinder.

No, the system will not experience three times the acceleration when three times the mass is added to one side of a pulley. The acceleration of a system is determined by the net force acting on it, which is equal to the mass of the system multiplied by its acceleration.

In the case of a pulley system, the net force on each side is equal to the gravitational force acting on the mass on that side, minus the tension force acting on it. Adding three times the mass to one side of the pulley will increase the gravitational force acting on that side, but it will also increase the tension force acting on it, which will counteract the increased gravitational force. As a result, the net force on the system will increase, but not by three times the amount. This will result in an increased acceleration, but not three times the acceleration.

Option a&e: A high-temperature cosmic source and a telescope designed and built to be launched into space are required for a successful x-ray image of a high-energy source.

X-ray are electromagnetic waves, which are a type of radiation. Images of the inside of your body are produced by X-ray imaging. The images depict various parts of your body in black and white. This is due to the fact that different tissues absorb varying amounts of radiation. Because calcium in bones absorbs the most x-rays, they appear white. Fat and other soft tissues absorb less and appear grayer as a result. Because air absorbs the least amount, the lungs appear black.

Suppose a gangster sprays superman's chest with 3 g bullets at the rate of 100 bulletslmin, and the speed of each bullet is 500 m/s. suppose too that the bullets rebound straight back with no change in speed. The magnitude of the average force on Superman's chest is 83,333 N.

To calculate the average force on Superman's chest, we need to calculate the impulse (change in momentum) from the rebounding bullets and divide by the time over which that impulse was delivered.

Impulse = Force * Time

Time = total mass of bullets / rate at which bullets were sprayed

Time = 3g / (100 bullets/min) = 0.03 g-min/bullet

Time = 0.03 g * 60 s/min = 1.8 s

Impulse = (mass of one bullet * velocity of one bullet) * number of bullets

Impulse = (0.001 g * 500 m/s) * 300 bullets = 150,000 kg m/s

Answer:

each spring will extend 0.049 m / 2 = 0.024 m.

Explanation:

The total spring constant of the two springs in series is 150 N/m (50 N/m + 100 N/m). The extension of the two springs can be calculated using Hooke's law:

F = kx

where F is the force applied to the spring (in this case, the weight of the 0.50 kg mass), k is the spring constant, and x is the extension of the spring.

So, x = F / k = (0.50 kg * 9.8 m/s^2) / 150 N/m = 0.049 m

This is the total extension of the two springs combined. To find the extension of each spring, we need to divide the total extension by the number of springs. Since there are two springs in series, each spring will extend 0.049 m / 2 = 0.024 m.
