Acceleration is defined as the rate of change for which of the followingA. time
B. velocity
C. position
D. displacement

Answers

Answer 1

Answer:

Acceleration is defined as the rate of change in the velocity of the moving object, therefore the correct answer is option B.

What is acceleration?

The rate of change of the velocity with respect to time is known as the acceleration of the object.

The rate of change of displacement is known as the velocity of the moving body and it is given by the expression,

velocity = d(displacement)/dt

The rate of change of velocity is known as the acceleration of the moving body and it is given by the expression,

acceleration = d(Velocity)/DT

Thus, acceleration is defined as the rate of change in the velocity of the moving object, therefore the correct answer is option B.

Answer 2

Answer:

The acceleration of the body is defined as the rate of change of velocity.

Further Explanation:

The body is said to be accelerating its velocity is changing with the time. The velocity of a particular body is defined as the rate of change of displacement of the body.

The velocity of a body is represented as:

$v=\frac{{dx}}{{dt}}$

Here, $x$ is the position of the body and $t$ is the time

Now when a body moves with a constant speed during its motion, then it is considered as the uniform motion of the body. During the uniform motion of the body, the acceleration of the body remains zero.

But if the velocity of the body is changing along with the time, the body is said to be accelerating. The acceleration of the body is defined as the rate of change of velocity of the body. It is represented mathematically as:

$\boxed{a=\frac{{dv}}{{dt}}}$

Thus, the acceleration of the body is defined as the rate of change of velocity.

A weight machine ____.A) Decreases the amount of input force required

B) reduces the amount of input work

C) changes the direction of the input force

D) increases the input distance

Answers

C) changes the direction of the input force

Explanation:

A weight machine measure the normal reaction of a body place on the machine.This means the force will have no acceleration. The body placed on the machine will thus exert the force due to gravity and the normal reaction will act in the opposite direction to it.

2. A force of 24x10² N exists between a positive charge of 8x10-5C and a positive charge of 3x10C.What distance separates the charges?

Answers

Answer: 94.9 metres

Explanation:

Given that,

Force between the two charges (F) = 24x10² N

Negative charge (q1) = 8x10-5C

Positive charge (q2) = 3x10C

Distance between charges (r) = ?

Apply the formula for

F= (kq1q2) / r²

Recall that k is Coulomb's constant with a value of 9 × 10^9 Nm2C−2

Then,

24x10² N = (9 × 10^9 Nm2C−2 x 8x10-5C x 3x10C) / r²

24x10² N = (2.16 x 10^7) / r²

r² = (2.16 x 10^7 / 24x10² N)

r² = 9000

To get the value of r, find the square root

r = √9000

r = 94.868m (rounded to the nearest tenth as 94.9m)

Thus, a distance of 94.9 metres separates the charges.

Explanation:

In the atmosphere water vapor condenses to form clouds. Please select the best answer from the choices provided T F

Answers

Answer: The given statement is True.

Clouds are formed due to condensation of water vapors. Condensation can be described as a process of change of gaseous form of water (that is water vapor) into liquid form.

When sunlight strikes various aquatic bodies, water is heated up and it rises high in the atmosphere in the form of water vapors.

When these vapors meet a lower temperature in the atmosphere, they cool and the air loses its capacity to hold them.

Due to this, vapors condense and form clouds.

Thus, given statement is True.
