The iceberg kid, infamous for imposing a deep freeze on whoever disagrees with him, discovers that in his advanced teenaged years his hands constantly feel chilled. as he is a cool physics student, the iceberg kid quickly calculates the resistance of the resistor needed to warm his hands. given that 181 j of thermal energy is generated by the resistor during 9.99 s of operation while connected to a 12.0 v battery, find the correct value of this resistance (and avoid a cold, cold fate).

Explanation:

First of all, we can calculate the power dissipated by the resistor. We have:

E = 181 J is the energy produced

t = 9.99 s is the time interval

So, the power dissipated is

But the power dissipated can also be written as

where

V = 12.0 V is the potential difference across the resistor

R is the resistance

Solving for R, we find

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
