Answer:

0.99 s

Explanation:

The period of a simple pendulum is given by:

T=2 \pi \sqrt{\frac{L}{g}}

where

L is the length of the pendulum

g is the acceleration due to gravity

In this problem, we have

L=24.6 cm=0.246 m

g=9.81 m/s^2

Substituting into the equation, we find the period:

T=2 \pi \sqrt{\frac{0.246 m}{9.81 m/s^2}}=0.99 s

The equation for period is T (period)=2\pi \sqrt{ \frac{L (length of string)}{g (gravity)}. Pluging in the length of the string in meters, .246, and 9.8 for gravity you come to the answer of 0.995 or about 1 second.

A small sphere attached to a light rigid rod rotates about an axis perpendicular to and fixed to the other end of the rod. relat
Crank
<span>d.rotating counterclockwise and slowing down This is a matter of understanding the notation and conventions of angular rotations. Positive rotations are counter clockwise and negative rotations are clockwise. An easy way to remember this is the "right hand rule". Make a closed fist with your right hand and have the thumb sticking outwards. If you orient your thumb such that it's pointing in the direction of the positive value along the axis, your fingers will be curled in the positive rotational direction. So in the described scenario, the sphere is rotating in the positive direction (counter clockwise) and decelerating due to the negative angular acceleration. That immediately indicates that options "a", "b", and "e" are wrong since they mention the sphere going clockwise at the beginning. Of the two remaining options "c" and "d", we can discard option "c" since it has the rotation speeding up, and that leaves us with option "d" where the sphere is rotating counter clockwise and slowing down.</span>

Goal posts at the ends of football fields are padded as a safety measure for players who might run into them. How does thick pad
zepelin [54]

The answer given by E2020 is

"The padding around the goal post increases the time of the collision between the player and the post, which decreases the force exerted to bring the player to a stop"
