Small ball is attached to one end of a spring that has an unstrained length of 0.245 m. the spring is held by the other end, and the ball is whirled around in a horizontal circle at a speed of 3.55 m/s. the spring remains nearly parallel to the ground during the motion and is observed to stretch by 0.0194 m. by how much would the spring stretch if it were attached to the ceiling and the ball allowed to hang straight down, motionless? number enter your answer in accordance to the question statement units choose the answer from the menu in accordance to the question statement

Explanation:

As we know that the force required to move the mass in circle with uniform speed is known as centripetal force

This centripetal force is given as

while mass is revolving in horizontal circle the force is due to spring so it is given as

now we have

now when mass is suspended at the end of spring then we have

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
