A 4.00 µf capacitor is connected to a 12.0 v battery.
atroni [7]
(a) The capacitance of the capacitor is:
C=4 \mu F=4 \cdot 10^{-6}F
and the voltage applied across its plates is
V=12.0 V

The relationship between the charge Q on each plate of the capacitor, the capacitance and the voltage is:
C= \frac{Q}{V}
and re-arranging it we find the charge stored in the capacitor:
Q=CV=(4 \cdot 10^{-6} F)(12.0 V)=4.8 \cdot 10^{-5} C

(b) The electrical potential energy stored in a capacitor is given by
U= \frac{1}{2}CV^2
where C is the capacitance and V is the voltage. The new voltage is 
V=1.50 V
so the energy stored in the capacitor is
U= \frac{1}{2}(4 \cdot 10^{-6} F)(1.50 V)^2=4.5 \cdot 10^{-6} J

Use the concepts of kinetic energy and potential energy to describe the motion of a child on a swing. Why does the child need a
andrew-mc [135]
When the child is moving, he/she has kinetic energy. For just a brief second before they move the other way, the child is not moving, but they have gravitational potential energy.

The child may need a push from time to time because friction with the air causes loss of energy.

Jasper made a list of the properties of electromagnetic waves. Identify the mistake in the list. Electromagnetic Wave Properties
Nata [24]

Answer:

Statement 2 is wrong

Explanation:

To check the statements in this exercise, let's describe the main properties of electromagnetic waves. Let's describe the characteristics

* they are transverse waves

* formed by the oscillations of the electric and magnetic fields

* the speed of the wave is the speed of light

with these concepts let's review the final statements

1) True. Formed by the oscillation of the two fields

2) False. They are transverse waves

3) True. Can travel by vacuum as they are supported by oscillations of the electric and magnetic fields

4) True. They all have the same speed of light

Statement 2 is wrong

Which statement describes the possible interaction(s) between two objects
Inessa [10]

Answer:

C. Gravitational forces only cause objects to be attracted to each

other, and magnetic and electric forces can cause objects to

attract or repel each other.
