Thermal energy is transforming, i think.
Answer:
I believe the answer is frequency
Hope this helps!! (let me know if it is right)

Answer:
Explanation:
The total charge in the disks

must be conserved before and after bringing them together.
Lets equate the sum of the initial charge with the sum of the final for the disk:


So, the initial charges must sum +17 μC.
Now, as there are no charges over +17 μC, this means that both charges must be positive.
As the only positive charges are
and
, this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:

Answer:
0.765m
Explanation:
gravitational potential energy GPE = mass * acceleration due to gravity * height
Given
GPE = 30Joules
Mass m = 4kg
acceleration = 9.8m/s²
Required
Height h
From the formula
h = GPE/mg
h = 30/4(9.8)
h = 30/39.2
h = 0.765m\
Hence the height of the counter is 0.765m
