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:
Explanation:
The volume of the shell is the difference between the volume of the outer sphere and the volume of the inner sphere
The mass of the shell is the product of the volume and its density
