Answer:
0 J
Explanation:
If it's at the same temperature then it doesn't need more heat. So it'd be 0 J since it's already at 0C.
Solid because the particles vibrate in place
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Answer:
The speed of the stone is 0.6138 c.
(B) is correct option.
Explanation:
Given that,
Mass of stone m= 0.6
Relativistic mass = 0.76
We need to calculate the speed
Using formula of rest mass


Put the value into the formula



Hence, The speed of the stone is 0.6138 c.
It’s 12 km
Because you multiply 8x1.5 and you get the answer.
