When hockey players push the puck along the ice it slides causing heat which melts the ice causing the friction against the ice to be less.
Answer:
P = 22 watts
Explanation:
Given that,
The output power of the generator = 2 a
The output potential difference = 11 V
We need to find the output power of the generator. The formula for the output power is given by :

So, the output power of the generator is equal to 22 Watts.
We can use the formula,
1/R = 1/r1 + 1/r2 + 1/r3 + ....
Hope this helps!
0, Because if they are pulling with equal force then they cancel each other out<span />
