Answer:
Explanation:
The formula that relates the luminosity of a star (L) to its radius (R) and the temperature (T) is
For star B, we can write:
For star A, we have
So the luminosity of star A is
Kinetic energy. It decreases as you move further away from the nucleus. Electrons further away from the nucleus are held more weakly by the nucleus and so can be removed by spending less energy which is why these electrons will have higher energy

The Effort Force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the distance over which the effort force is exerted.
Answer:
Volume of gasoline that expands and spills out is 1.33 ltr
Explanation:
As we know that when temperature of the liquid is increased then its volume will expand and it is given as
here we know that
volume expansion coefficient of the gasoline is given as
change in temperature is given as
Now we have
Answer:
326.4 mC
Explanation:
The relationship between charge, capacitance and voltage in a capacitor is given by
where
C is the capacitance
Q is the charge
V is the voltage
In this problem, we have
C = 34 mF is the capacitance
V = 9.6 V is the voltage
Re-arranging the equation and substituting the numbers, we find the charge stored in the capacitor:
