The statement: “According to Faraday's law, voltage can be changed by moving magnets away from the coil of wire.”, is true. Any type of movements done (away, into or out, toward, rotation, etc.) on the magnetic environment would always generate a voltage. In Faraday’s law, it is clear that there are different ways on how to generate a voltage.

arlik [135]

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.

How does Newton's second law of motion can be used to calculate the acceleration of an object?
Alex777 [14]

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.

At what speed must a 0.6 kg stone be thrown in order that it has a relativistic mass of 0.76 kg? (c = 3.00 x 10^8 m/s) A) 0.6976
soldier1979 [14.2K]

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

m_{r}=\dfrac{m_{0}}{\sqrt{1-\dfrac{v^2}{c^2}}}

v^2=(\dfrac{m_{0}^2}{m_{r}^2}-1)c^2

Put the value into the formula

v^2=(\dfrac{0.6^2}{0.76^2}-1)\times c^2

v=\sqrt{0.37673c^2}

v=0.6138c

Hence, The speed of the stone is 0.6138 c.
