Answer:
The increase in thermal energy results in an increase in pressure.
Explanation:
- The increase in entropy is directly related to the increase in temperature. So the thermal energy in heat engine increases the temperature of that surrounding.
- Higher temperature means the kinetic energy of particles is also higher, their vibration is increasing. So it increases the pressure (ideal gas law).
- In this way the increment in the thermal energy in heat engine moves piston by increasing the pressure.
Answer:
Explanation:
Given parameters:
Electrical energy = 18J
Quantity of charge Q = 12C
Unknown:
Voltage = ?
Solution:
The expression of electrical potential energy is given as:
Electrical potential energy =
c v²
c is the quantity of charge
v is the voltage
18 =
x 12 x v²
18 = 6v²
v² = 3
v = 1.7v
Your answer would be B.
