Answer 1
The formula is F = 9x10^9 x q1 x q2 / r^2

Force = 9x10^9 x (4.2x10-9 x 1.1 x 10^-9) / 0.005^2

A force of 49N causes a box to move with an acceleration of 7m/s2. Find the mass of the object

Answers

Answer:

The answer is 7 kg

Explanation:

To find the mass of the object given the force and acceleration we use the formula

[tex]m = \frac{f}{a} \\ [/tex]

where

f is the force

a is the acceleration

m is the mass

From the question

f = 49 N

a = 7 m/s²

We have

[tex]m = \frac{49}{7} \\ [/tex]

We have the final answer as

7 kg

When a body like earth is moving in a circular path the work done in that case is zero because: (a) Centripetal force acts in the direction of motion of the body (b) Centripetal force acts along the radius of circular path (c) Gravitational force acts along the radius of circular path (d) Centrifugal force acts perpendicular to the radius of circular path

Answers

Answer:

(b) Centripetal force acts along the radius of circular path

Explanation:

Centripetal force is a force experienced by a body moving in a circular path. It is expressed mathematically ad F = mv²/r

m is the mass of the body

v is the velocity

r is the radius of the circular path

When a body moves in a circular path, work dome is zero because Centripetal force acts along the radius of circular path and the force is at right angle with the motion of body.

Explanation:

A meteoroid is a piece of stony debris that float in space and move around the sun in different orbits and speeds.

Meteoroids enter into Earth's surface with a high speed as shooting stars and called meteors. Meteors move through the atmosphere and landed on the surface and it is called a meteorite.

Hence, the correct answer is "D."

You throw a ball straight up into the air at a velocity of 15 m/s. You want to know how high above your hand the ball will be at exactly 2.5 sec after you released it. You must SHOW ALL WORK to receive credit!!! Of the 5 motion variables - Vi, Vf, a, ΔX, and T, identify which one you are solving for and the magnitudes and directions of all of the others that are known: Which of the motion equations is best to use to determine the height of the ball? How high is the ball above your hand at 2.5 sec after you throw it?

Answers

Answer:

6.875m

Explanation:

Given

Velocity = 15m/s

Time = 2.5secs

Required

Distance above your hand the ball will be at exactly 2.5secs

using the equation of motion:

ΔX = ViT + 1/2aT²

ΔX is the distance

Vi is the velocity of the ball in air

a is the acceleration due to gravity

T is the time taken

Since the ball is thrown straight up, a = -g

ΔX = ViT - 1/2gT²

Substitute

ΔX = 15(2.5) - 1/2(9.8)(2.5)²

ΔX = 37.5-30.625

ΔX = 6.875m

Hence the ball will be 6.875m above your hand at 2.5secs after you throw it.

What is radioactivity?

The nucleus of an atom exhibits the phenomenon of Radioactivity due to its instability. Energy will be lost due to the emission of radiation from the unstable nucleus of an atom.

The electrostatic force of repulsion and the powerful forces of attraction keep the nucleus together. The instability increases as the size of the nucleus increases because the mass of the nucleus increases when concentrated. Therefore, Plutonium, Uranium is extremely unstable and undergoes radioactivity.

The emitted radiation from radioactivity always consists of alpha, beta, and gamma particles. Gamma Decay is photons having high energy, Beta Decay consists of Electrons while Alpha Decay consists of a Helium nucleus.

A spray gun, used to apply paint, uses Bernoulli's principle to function. It contains two tubes inside of it: one tube comes up from the supply of paint and one supplies a flow of compressed air that blows across the top of the paint tube. This rush of air creates ____, which sucks the paint up the tube and into the stream of air.

Answers

Answer:

Low pressure

Explanation:

Take two nearby points at the junction of both the tube, let point 1 be in the air tube while point 2 be in the paint tube.

According to Bernoulli's principle, the air at point 1 is moving with some speed which causes the pressure drop inside tube 1, while at point 2 there is no velocity, so there is no pressure drop at that point. In fact, the pressure at point 2 approximately equals the atmospheric pressure.

As both the points are taken is nearby at the junction, to the pressure drop in the flow air pipe causes the suction of fluid from the relatively high-pressure tube (paint tube).

Hence, this rush of air creates low pressure, which sucks the paint up the tube and into the stream of air.

An object weighs 530.0 Newton. It is being pushed along a horizontal surface by a 340.0-
Newton force. Determine the mass of the object. Enter a numerical answer.

Answers

Answer:

54.08 kg

Explanation:

The weight of an object is the force of gravity acting on the object and is related to the mass of the object as;

Weight = mass x acceleration due to gravity (g), where g = 9.8 m/s.

Hence, the weight of the object is only dependent on its mass and g, not on any other force. Now, if the weight is 530.0 N,

530 = m x 9.8

   m = 530/9.8

                = 54.08 kg

Therefore, the weight of the object is 54.08 kg.

A 55 kg boy is throwing a 0.23 kg baseball up in the air. He decides to see how high he can throw it and uses a timer to see how long the ball stays in the air. He throws the ball as hard as he can straight up in the air and finds that it takes 5.5 seconds to come back to him. How long did it take for the ball to reach its highest point? (half the time it was in the air)

Answers

Answer:

2.75 s

Explanation:

From the question given above,

Total time (T) spent by the ball in air = 5.5 s

Time taken (t) to reach the greatest height =...?

Thus, we can obtain the time taken (t) for the ball to reach the greatest height as follow:

T = 2t

Where:

T is the total time spent by the ball in air.

t is the time taken to reach the greatest height

Total time (T) spent by the ball in air = 5.5 s

Time taken (t) to reach the greatest height =...?

T = 2t

5.5 = 2 × t

Divide both side by 2

t = 5.5/2

t = 2.75 s

Therefore, the time taken (t) to reach the greatest height is 2.75 s.
