Actually, the best way to put it would be if the current is too large or too small.
Fuses and circuit breakers are both devices that "break" if the current flowing through them is too large.
A fuse is usually a thin piece of wire that will melt and break the circuit if too large a current flows through it. The thicker the fuse wire, the more the current needed to melt it and the higher the "rating" of the fuse. The function of the fuse is to protect the wiring and the equipment.
A circuit breaker is an electronic circuit that will switch off the current if it is too great. A circuit breaker is designed to operate much more quicker than a fuse and so the damage is less because the current is switched off in a much shorter time.
Answer:
The correct answer is <u>option (A) that is KEA > KEB .</u>
Explanation:
Let us calculate -
If the object is straighten up and inclined plane , the work done is


The change in kinetic energy is ,

At the top of the inclined plane , the velocity is zero
So,


From the work energy theorem , we have
in case of friction , so


For object A-

For object B


Thus , larger mass is going to mean less total work and a lower kinetic energy .
From the above results , we get

<u>Therefore , option A is correct .</u>
When a large rock is weathered into tiny pieces which add up the weight of the original rock, this demonstrates the law of conservation of matter.
According to this law the mass of an object doesn't change with time and also it does not depends on how the particles are arranged themselves.
Hence, option (C) is correct.
Answer: a disadvantage of using a ramp is that it is not safe
