The absolute simplest way to explain E=MC^2 is: a lot of energy from a little mass.
Answer:
NS/NS
Explanation:
If we cut a bar magnet in half pieces according to the image that is given below the question, then the magnet will show NS/NS that is (North-South/North-South) because the smaller pieces of the magnet will become a small magnet with the same property-carrying both the poles, north pole as well as south pole. The poles will not be separated.
Answer:
The magnification would be "103.55". A further explanation is given below.
Explanation:
The given values are:
Distance between lens and eyepiece,
L = 85 cm
Eyepiece is,
= 123 D
Now,
The refractive power of eye piece will be:
⇒ 


The length of the telescope will be:
⇒ 
⇒ 
On substituting the values, we get
⇒ 
⇒ 
Now,
The magnification of the telescope will be:
⇒ 
⇒ 
⇒ 
The velocity of the ball is constantly changing because its direction is changing.
The acceleration of the ball is constant and perpendicular to the velocity, towards the center of the circle. The force is also in this direction and constant.
The displacement after one complete revolution is 0.
