Acceleration =change in velocity/change in time.
So final speed minus initial velocity/time
3.1-v/2=a
C.) A thunderstorm
That’s the Answer
Answer:
Lightning
Explanation:
Air is a non-conductor of electricity because it does not have free electrons to carry the current. But when there is a high voltage, as in the case of lightning, the molecules of air get ionized and electrons are available to flow to make the current and conduct electricity through the air.
Ashley ran with a speed of 12 feet per second.
Speed is measured as the ratio of the distance travelled to the time it took to cover that distance.
Since speed simply has a magnitude and no direction, it is a scalar quantity.
The formula for the speed of an object/body is given as-
where, d is the distance travelled by the body/object and t is the time taken by the body/object to cover the distance
Ashley has covered a distance of 264 feet and the time taken to cover this distance is 22 seconds.
Now, Ashley’s speed can be calculated by dividing the distance of 264 feet to the time taken by Ashley cover this distance, i.e.
Thus, the speed with which Ashley ran was 12 feet per second.

Answer:
Explanation:
Natural length of the string is given as
length of the string while block is hanging on it
extension in length is given as
now we have strain in the string is given as
similarly we will have cross-sectional area of the string is given as
now the stress in the string is given as
Now Young's Modulus is given as
