Newton's first law of motion - sometimes referred to as the law of inertia. Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
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.
Answer:
25km/h

Since there is no temperature change which drives heat flow, thus no heat will be released by the water.
<h3>
Heat released by the water when it freezes</h3>
The heat released by the water when it freezes is calculated as follows;
Q = mcΔФ
where;
- m is mass of water
- c is specific heat capacity of water
- ΔФ is change in temperature = Фf - Фi
when water freezes, the temperature, Фf = 0 °C
Q = 82 x 4200 x (0 - 0)
Q = 0
Since there is no temperature change which drives heat flow, thus no heat will be released by the water.
