Answer:
I THINK it would be False.
Answer:
All of the choices are correct
Explanation:
The power dissipated in a single resistor connected to a battery is given by:
where
V is the voltage
I is the current
R is the resistance
Let's analyze each case:
A) Doubling the voltage (V'=2V) and reducing the current by a factor of 2 (I'=I/2). The new power dissipated is:
--> the power is unchanged
B) Doubling the voltage (V'=2V) and increasing the resistance by a factor of 4 (R'=4R). The new power dissipated is:
--> the power is unchanged
C) Doubling the current (I'=2I) and reducing the resistance by a factor of four (R'=R/4). The new power dissipated is:
--> the power is unchanged
Answer:
<em>The thermal energy of an object depends on its temperature and mass. The higher the temperature of a substance, the more thermal energy it has. For the same temperature, a substance with a higher mass will also have more thermal energy.</em>
