which process of the method a neutral object obtains an. electrical charge

Answer:

The graph of the velocity of an object in free fall would look like a straight line sloping downward. As the object falls, its velocity increases at a constant rate, so the graph of its velocity versus time will be a straight line with a negative slope. This is because acceleration due to gravity is a constant -9.8 meters per second squared, so the velocity of a free-falling object will increase by 9.8 meters per second every second.

Therefore, the graph that shows the change in velocity of an object in free fall is a straight line with a negative slope. Here is an example of such a graph:

Answer:

The period of motion is 0.5 second.

Explanation:

Given;

extension of the spring, x = 3.8 cm = 0.038 m

mass of the object, m = 13 g = 0.013 kg

Determine the force constant of the spring, k;

F = kx

k = F / x

k = mg / x

k = (0.013 x 9.8) / 0.038

k = 3.353 N/m

When the object is replaced with a block of mass 20 g, the period of motion is calculated as;

\(T = 2\pi\sqrt{\frac{m}{k} } \\\\T = 2\pi\sqrt{\frac{0.02}{3.353} } \\\\T = 0.5 \ second\)

Therefore, the period of motion is 0.5 second.

Answer: The force that makes the ball move in a circle around the pole is an angular force known as CENTRIPETAL FORCE.

Explanation:

When a stone is attached to a string, just as in the tetherball game, and whirled round at constant speed in a horizontal circle, the stone moves with constant speed but at different directions and acceleration ( as the ball is hit by different players) directed towards the center of the circle due to the tension in the spring that produces a force.

The force that is required to keep the object ( ball) moving in this circular path is called the centripetal force. It is inversely proportional to the radius curvature (r) which is formed by the rope that ties the ball to the pole. Therefore, the force increase as the radius decreases.

Hence,

F= mv²/ r

Where F= centripetal force

m= mass

v= velocity

r= radius of curvature

Horizontal component of pull = (cos 55 x 33.9) = 19.4N.

Net horizontal force = (19.4 - 14.2) = 5.2N.

Work = (fd) = (5.2 x 13.5) = 70.2 Joules.

Rounded to 1 decimal place throughout.

Explanation:

The total work done on the vacuum is 70.2 J.

What is work done?

Work done is equal to product of force applied and distance moved.

Work = Force x Distance

Given is a custodian pulls a vacuum 13.5 m with a 33.9 N force at a 55.0° angle, against a 14.2 N friction force.

Horizontal component of pull = (cos 55 x 33.9) = 19.4N.

Net horizontal force = (19.4 - 14.2) = 5.2N.

Work done by vacuum will be

Work =5.2 x 13.5

Work =70.2 J

Thus, the total work done on the vacuum is 70.2 J.

The cannon will completely stop when it collides with the barrier.

To calculate the speed at which the cannon collides with the barrier, we can follow these step-by-step calculations:

Determine the initial momentum of the system.

Since the cannon is initially stationary, the initial momentum is zero.

Apply the conservation of linear momentum.

According to the principle of conservation of linear momentum, the initial momentum of the system (zero) is equal to the final momentum of the system. The final momentum is the momentum of the cannon after firing.

Calculate the final momentum of the system.

Let's assume the mass of the cannon is represented by 'm' and the final velocity of the cannon is represented by 'v'. The final momentum of the system is given by: final momentum = m × v.

Set up the equation.

Since the initial momentum is zero, we have: 0 = m × v.

Solve for the final velocity of the cannon.

Dividing both sides of the equation by 'm', we get: v = 0.

Interpret the result.

The calculation shows that the final velocity of the cannon is zero. This means that the cannon comes to a complete stop when it collides with the barrier.

velocity = 7.5 yards / second

Answer:

the velocity of the ball is 7.5 yards/second

Explanation:

The answer is B) I. The electric field will have the greatest magnitude at point I because it is the closest point to the charged conductors. The closer to the conductors, the greater the electric field magnitude.

Electric field is an invisible force field that surrounds any object that has an electric charge. It is measured in terms of volts per meter (V/m) and is responsible for the attraction or repulsion of two objects with different electric charges. The force of the electric field is determined by the amount of charge on the objects and the distance between them. Any changes in the electric field will cause a corresponding change in the force felt by the objects. Electric fields can be created by moving charges, such as those found in electric currents, or by static charges, such as those found on a charged object. Electric fields are essential for the transmission of electrical signals and are used in many applications, from telecommunications to medical imaging.

Answer:

7.9 \(\frac{m}{s^{2} }\)

Explanation:

Take the fact that mass is inversely proportional to accelertation:

m ∝ a

Therefore m = a, but because we are finding the change in acceleration, we would set our problem up to look more like this:

\(\frac{m_{1} }{m_{2} } = \frac{a_{2} }{a_{1} } \\\)

Using algebra, we can rearrange our equation to find the final acceleration, \(a_{2}\):

\(a_{2} = \frac{a_{1}*m_{1} }{m_{2} } \\\)

Before plugging everything in, since you are being asked to find acceleration, you will want to convert 0.85g to m/s^2. To do this, multiply by g, which is equal to 9.8 m/s^2:

0.85g * 9.8 \(\frac{m }{s^{2} }\) = 8.33 \(\frac{m }{s^{2} }\)

Plug everything in:

7.9 \(\frac{m }{s^{2} }\) = \(\frac{ 8.33\frac{m}{s^{2} }*1510kg }{1590kg}\)

(1590kg the initial weight plus the weight of the added passenger)

Approximately 3,299.9 J of energy was transferred into thermal energy during the fall of the diver.

To determine the amount of energy transferred into thermal energy during the fall of the diver, we can use the principle of conservation of energy.

The initial potential energy of the diver at the maximum height is given by:

Potential Energy (PE) = m * g * h

Where:

m = mass of the diver (48.0 kg)

g = acceleration due to gravity (9.8 m/s^2)

h = maximum height (11.0 m)

Substituting the given values:

PE = 48.0 kg * 9.8 m/s^2 * 11.0 m = 5,219.2 J

The final kinetic energy of the diver just before hitting the pool is given by:

Kinetic Energy (KE) = (1/2) * m * v^2

Where:

m = mass of the diver (48.0 kg)

v = speed of the diver (8.81 m/s)

Substituting the given values:

KE = (1/2) * 48.0 kg * (8.81 m/s)^2 = 1,919.3 J

The difference between the initial potential energy and the final kinetic energy represents the energy transferred into thermal energy:

Energy transferred into thermal energy = PE - KE

                                     = 5,219.2 J - 1,919.3 J

                                     = 3,299.9 J

Therefore, approximately 3,299.9 J of energy was transferred into thermal energy during the fall of the diver.

Explanation:

The crate (92 kg) will be slide on the rough floor with kinetic friction about 0,2.

Minimum force is required to allow the crate moves, which is calculated as follows :

Kinetic friction is formed because there are two or more things are sliding together. In this case, crate and floor are rubbing each other. Kinetic friction can cause the speed of things decreased.

Crate need a bigger force than the friction one to make it move.

So, we can calculate the value of a kinetic friction first.

f = μ x N

f = friction (Newton)

μ = coefficient of kinetic friction

N = Normal force (Newton)

f = μ × N

f = 0,2 × m × g

f = 0,2 × 92 × 10

f = 2 × 92 = 184 N

So, Crate need more than 184 N or bigger than a kinetic friction to allows it move.

Answer:

v_wind = 101.46 km / h   ,  θ = 61.8

Explanation:

This is a velocity composition exercise.

Let's do the problem in parts. Let's start by knowing the speed of the plane without air.

           v = d / t

           v = 750 / 3.14

           v = 238.85 km / h

This is the speed of the plane relative to the Earth and it does not change.

In the second part, when there is wind, the travel time is greater than when there is no wind, therefore the wind delays the plane. To be more general, suppose that the wind has two components vₓ and \(v_{y}\)

Let's use trigonometry to find the components of the plane's speed

          cos θ = v_N / v

          sin θ  = v_W / v

          v_N = v cos θ

          v_W = v sin θ

let's calculate

          V _N = 238.85 cos 22 = 221.46 km / h

           v_W = -238.85 sin 22 = -89.47

the negative sign is because the plane is going west and the positive sign is the east direction.

As it indicates that the destination of the avine is towards the north, the x component of the wind must be

              vₓ - v_W = 0

              vₓ = v-w

              vₓ = 89.47 km / h

in the direction to the East.

Now let's analyze the component of the wind in the Nort-South direction,

Indicate the travel time, let's calculate the speed that the component must have the speed of the plane

             v_total = d / t

             v_total = 750 / 4.32

             v_total = 173.61 km / h

This is the final speed of the plane, which can be written

              v_total = v_n - vy

               vy = v_n - v_total

               vy = 221.46 - 173.61

               vy = 47.85 km

this component is directed towards the south

Let's use the Pythagorean Theorem, to find the magnitude

             v_wind² = vₓ² + vy²

             v_wind = √ (89.47² + 47.85²)

             v_wind = 101.46 km / h

the address will then be found using trigonometry

             θ = Vy / vx

             θ = tan⁻¹ (vy / vx)

             θ = tan⁻¹1 (47.85 / 89.47)

             θ = 28.14

Therefore, the magnitude of the wind speed is 101.5 km / h and its direction is 28º south of the East, to give this value

                  90- θtea = 90- 28.2

                  θ = 61.8

The force that acts on a projectile in the horizontal direction is Gravitational force.

A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.

Due to the absence of horizontal forces, a projectile remains in motion with a constant horizontal velocity. Horizontal forces are not required to keep a projectile moving horizontally. Hence, The only force acting upon a projectile is gravity.
