Answer:
One end of any bar magnet will always want to point north if it is freely suspended. This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole.
Explanation:
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.
<h3>What is acceleration?</h3>
The term acceleration has to do with the rate at which velocity changes with time.
We have to take the moments at the tipping point of rotation as follows;
Clockwise moment = Anticlockwise moment
Hence;
F₂ * 1.58 m = F₁ * 0.67 m
The weight at half the width= 30 cm or 0.3 m
Height of refrigerator = 158 cm 0r 1.58 cm
Then;
m * a * 1.58 = m * 9.81 * 0.30
a = 1.86 m/s²
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.

Answer:
D
Explanation:
The reason why it's D is because it show a real life example were you can use velocity
In the question where as a model rocket is launched straight upward with an initial speed of 50.0m/s and it accelerate with a constant acceleration of 2m/s^2 until it engines stop at an altitude od 150. So the following are the answer to your question:
a.The motion, the acceleration was equals to Zero
b.the maximum height is 150m
Answer:
Velocity of electron will be equal to 
Explanation:
We have given kinetic energy of electron 
Mass of electron 
We have to find velocity of electron
Kinetic energy of electron is equal to 
, here m is mass and v is velocity
So 
So velocity of electron will be equal to
