Answer:
a. Wgra=786.09J
b. 1.28m
Explanation:
The change in the potential energy is the work done by the gravitational force.
For this problem you have to take into account that the total work done is given by the change in the kinetic energy
Furthermore the total work is the contribution of the work done by the skater, the gravitational force and the friction
(a) by separating Wfric you have
(b) It is only necessary to use the expression for the work done by gravitational force
HOPE THIS HELPS!!
A is the answer: A resistor, which converts some electrical energy to thermal.

Answer:
most likely 0m/s bc it was dropped, so it had to be still before
Explanation:
First of all due to heavy rainfall , people are facing different current and electric circuit issues ..Heavy ranfall and thunder storm is the main reason of the issue.. So , The conclusion are given below -"
•We can make the roadside wires underground .
•We can also follow basic safety measures .
•We can avoid using devices having wifes with the plugin .
•We can use non-Elextirc devices more .
