Chapter 2: Problem 10

The ratio of unit of acceleration and velocity gives unit of the physical quantity _ (1) time (2) frequency (3) amplitude (4) speed

Short Answer

Expert verified
Answer: (1) time

Step by step solution

01

Write down the units of acceleration and velocity

The units of acceleration are meters per second squared (m/s^2), and the units of velocity are meters per second (m/s).
02

Divide the units of acceleration by the units of velocity

To determine the units of the resulting physical quantity, divide the units of acceleration by the units of velocity: (m/s^2) / (m/s) = (m/s^2) * (s/m)
03

Simplify the expression

Now, let's simplify the expression by canceling the same units in the numerator and the denominator: (m/s^2) * (s/m) = (m * s) / (s^2 * m) = 1/s The resulting unit is 1/s, which is the unit of **time**.
04

Choose the correct answer

The physical quantity with the unit 1/s is time. Therefore, the correct answer is: (1) time

The speed of the tip of a second hand of length \(5 \mathrm{~cm}\) of a clock is \(\mathrm{m} \mathrm{s}^{-1}\) (1) 1 (2) 60 (3) \(5.3 \times 10^{-3}\) (4) \(3.4 \times 10^{-5}\)

If the speed of an object is known, how can we find the distance covered by it in a given time?

Choose the correct statement: (1) The magnitudes of speed and velocity are same when a body travels in a straight line path. (2) Average speed of a moving body can be equal to zero, but its average velocity cannot be equal to zero. (3) To describe the velocity, direction is necessary. (4) Both (1) and (3)
