2,450 Joules, kinetic energy is 1/2 mass x velocity squared.
The formula of net Force is:F = mawhere m is the mass of the objecta is the acceleration of the object
thus, if we triple the net force applied to the object:
3F = maa = 3F / m
The acceleration is also tripled since the force is directly proportional to the acceleration.
The gravitational force of attraction between two objects would be increased by "decreasing the distance between two objects"
Hope this helps!
Answer:
The output power is 2 kW
Explanation:
It is given that,
Number of turns in primary coil, 
Number of turns in secondary coil, 
Voltage of primary coil, 
Current drawn from secondary coil, 
We need to find the power output. It is equal to the product of voltage and current. Firstly, we will find the voltage of secondary coil as :



So, the power output is :



or

So, the output power is 2 kW. Hence, this is the required solution.
