Contact forces are forces that require the actual contact (touching) of two pieces of matter. ... A field force is a force that works at a distance. No touching is required. Gravity is a good example of a field force, because it works whether or not an object is touching something or touching nothing at all.
Answer:
The value of R and the internal resistance of the battery are 10.6 ohm and 2.45 ohm
Explanation:
Given that,
Emf of battery = 15.0 V
Voltage = 12.2 V
Power = 14.0 W
(a). We need to calculate the value of R
Using formula of power
Where, R = resistance
P = power
V = voltage
Put the value into the formula
(b). We need to calculate the internal resistance of the battery
Firstly we calculate the current
Using formula of current
Put the value of P and V into the formula
We calculate the internal resistance
Using formula of emf
Put the value into the formula
Hence, The value of R and the internal resistance of the battery are 10.6 ohm and 2.45 ohm
