Answer:
<u>The transformation of energy in a torch light is as follows:</u>
1) When the torch is turned ON, the chemical energy in the batteries is converted into electrical energy.
2) The electrical energy is converted into heat and light energy. (We feel the torch to be hot after some time and we can see the light energy)
Hope this helped!

Answer:
The difference lies in the planets' respective magnetic fields, because while Earth's magnetism comes from within, Mars' does not. Earth's magnetism comes from its core, where molten, electrically conducting iron flows beneath the crust. Its magnetic field is global, meaning it surrounds the entire planet
Explanation:
thanks for question
For an ideal transformer power loss is assumed to be zero
i.e. the power in primary coil due to input voltage must be equal to power in secondary coil due to output voltage
this can be written in form of equation

here we know that


![i_1 = 10 A{/tex]now we will use above equation[tex]140*3.5 = 10 * V_1](https://tex.z-dn.net/?f=i_1%20%3D%2010%20A%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3Enow%20we%20will%20use%20above%20equation%3C%2Fp%3E%3Cp%3E%5Btex%5D140%2A3.5%20%3D%2010%20%2A%20V_1)

So primary coil voltage is 49 Volts
We Know,
K.E. = 1/2 mv²
480 = 1/2 (m)(8)²
m = 960/64
m = 15 Kg
So, the mass of the object is 15 Kg
