Answer:

Nuclear Energy

Explanation:

Nucleus of an atom is strongly bonded by nuclear force which is very strong so due to this strong force there is huge potential energy which is also known as nuclear energy.

When this nucleus is divided into small parts then this nuclear energy is released and it is known as nuclear energy.

Out of all type of fundamental forces the nuclear force is maximum force is due to nuclear force and hence this is the maximum energy above all

so here correct answer will be

C. The speed will remain the same.

If a 9 V battery with 4 Ω contact resistance is used and the relay has 80 Ω and the wire has 10 Ω/mile, what is the maximum tele

Sedaia [141]

Answer:

Telegraph distance will be 9.6 mile

Explanation:

We have given the voltage V = 9 volt

Contact resistance = 4 ohm

Relay resistance = 80 ohm

And wire has a resistance = 10 ohm/mile

We have given the current = 50 mA =0.05 A

According to ohm's law $R=\frac{V}{I}=\frac{9}{0.05}=180ohm$

So the resistance of wire = 180-4-80=96 ohm

So the length of the telegraph distance will be $\frac{96}{10}=9.6mile$

A 1500 kg car is moving 18 m/s how much force is required to bring the car to a stop in 12 seconds

Marat540 [252]

Answer:

2250N

Explanation:

F = Mv/t

Force F =?

Mass M = 1500kg

Velocity v = 18m/s

Time T = 12 secs

Therefore

F = 1500 x 18 /12

Multiply through

F = 27000/12

F = 2250N
