Well, well, well! Let's get rolling with some answers, shall we? So, let's start with the distance covered by the body. Since it's going in a circular path, we know that the distance covered in one revolution is the circumference of the circle, which is 2πR.

In 20 seconds, the body covers one revolution, so the distance covered in 20 seconds is 2πR.

Now, when it comes to the displacement, things get a bit funky. Displacement is the shortest distance between the initial and final positions of the body. In this case, the body is going in a circle, so it'll end up back where it started after a certain number of revolutions.

In 70 seconds, the body takes 3.5 revolutions (70/20 = 3.5). Therefore, the body's final position will be the same as its initial position. As a result, the displacement is a big, fat zero.

So, to sum it up, the distance covered by the body at the end of 70 seconds is 3.5 times the circumference of the circle (3.5 * 2πR), and the displacement is a big, fat zero. Keep on rotating!

To calculate the distance and displacement of the body at the end of 70 seconds, we need to first understand the motion of the body.

Given that the body covers a circular path of radius 'R' in 20 seconds, we can calculate the circumference of the circle using the formula:

Circumference = 2 * π * R

The distance covered by the body over the course of 20 seconds will be equal to the circumference of the circle.

Distance = Circumference = 2 * π * R

Now, to calculate the distance covered by the body at the end of 70 seconds, we need to determine the number of complete circles the body has covered. Since the body completes one full circle in 20 seconds, after 70 seconds, the body will have completed:

Number of Circles = 70 seconds / 20 seconds

Next, we can calculate the distance covered by the body over the 70 seconds by multiplying the number of circles by the circumference of the circle.

Distance = Number of Circles * Circumference

Now, we can substitute the values to get the final result.

Distance = (70 seconds / 20 seconds) * (2 * π * R)

To calculate the displacement, we need to determine the net change in position of the body. Since the body is moving in a circular path, the displacement will be equal to the final position minus the initial position.

Since the body starts at a specific point on the circular path, after completing one full circle, it will return to the same point. Hence, the displacement will be zero.

Displacement = 0

Therefore, the distance covered by the body at the end of 70 seconds is given by (70/20) * (2 * π * R), and the displacement is zero.
