Answer:
the gravitational pull is stronger the closer the object is to the magnet but gets weaker as you move the object away from the magnet
Explanation:
if you hold a magnet right over a nail it immediately shoot up onto the magnet
were as if you hold it at a distance it will move but not as fast
Yes you should if you will like to. It is your opinion so follow your dreams if they are your dreams.
Answer: Because multiple sounds will be heard over and over again thereby leading to noise and even confusion
Explanation: The reflection of sound waves from a hard surface is called echo and the multiple occurrence of echo is called reverberation.
During concert, several sound waves are released from the source (speaker). However, if the concert takes place in a gym, reverberation will occur.
A gym is a made up of a large space with little or no sound absorbing surfaces (such as sofas and carpets) thereby giving room for reverberation, that is sound waves will be frequently reflected until the sound wave exhausts it's energy. This will result in noise as the same sound will be heard repeatedly and will further lead to imbalance and confusion.
Answer:
-0.9 m/s²
Explanation:
t = Time taken by the hockey puck = 7 seconds
u = Initial velocity of the hockey puck = 13 m/s
v = Final velocity of the hockey puck = 6.7 m/s
a = Acceleration of the hockey puck
Equation of motion
The acceleration of the hockey puck in the seven seconds is -0.9 m/s²
The acceleration due to gravity is not needed to find the acceleration of the puck.
force times gravity (FG) =mass times gravity (mg)
