Answer:
The angular speed of rolling ball is 3.23 rad/sec.
Explanation:
Given that,
Radius = 1.95 cm
Speed = 6.30 cm/s
Suppose, we need to find the angular speed of rolling ball
We need to calculate the angular velocity
Using formula of angular velocity

Where, r = radius
= angular velocity
Put the value into the formula



Hence, The angular speed of rolling ball is 3.23 rad/sec.
<span>Sound travels faster in water than in air because water has closer particles than in air. This means that the wavelength of sound in water is larger and longer. and its frequency is lower than the sound as heard in the air.</span>
