Answer:
Hey
Your answer would be:
stationary objects within the field will move when realesed.
The reason why is because fields store potential energy as you know. when something is stationary it has potential, but when it is released that potential energy turns into kinetic energy.
this made me think of a funny joke:
A man was about to jump off of the Empire State Building when a physicist from below yield, Wait don't! you have so much potential!
lol always cracks me up.
The answer would be D. by adding lava to the Earth’s surface. When it hardens this can make rocks.
Answer:
the safe's coefficient of kinetic friction on the bank floor is
Explanation:
GIven that:
Bonnie and Clyde are sliding a 325 kg bank safe across the floor to their getaway car.
So ,let assume they are sliding the bank safe on an horizontal direction
Clyde → Δ(bank safe) → Bonnie
Also; from the above representation; let not forget that the friction force is acting in the opposite direction ←
where;
=
The safe slides with a constant speed
If Clyde pushes from behind with 377 N of force while Bonnie pulls forward on a rope with 353 N of force.
Thus; since the safe slides with a constant speed if the two conditions are met; then the net force acting on the slide will be equal to zero.
SO;
Since the net force acting on the slide will be equal to zero.
Then;
Also; let and
Then;
where;
Then;
Thus; the safe's coefficient of kinetic friction on the bank floor is
Answer:
<h2>The potential difference is 60mV</h2>
Explanation:
This problem bothers on application of the expression for motion emf which is expressed as
where B= magnetic field in Tesla
l= length of the conductor
v= speed of conductor
Given data
l= 2 meters
v= 6 m/s
B= 5 Tesla
Applying the formula we have
