<span>Just add the two kinetic energies;
E = (1/2)mv^2 + (1/2)mv^2</span>
True. The mass of an electron is about 1/2000 amu whereas the mass of a proton is 1 amu.
Electric blankets have insulated wiring woven into them. When plugged in and turned on, the <em>electric energy</em> recieved from the electrical outlet is <u>transferred to </u><u>heat</u><u>.</u>
Electricity naturally produces heat when conducting, and by using insulation on the wires, this temperature can be controlled and gently warm the person whom the blanket is covering.
To solve this problem we will apply the concepts related to energy conservation. For this purpose we will have that all the changes occurred in the energy change will be equivalent to the change in the potential and kinematic energies of the body. At the same time we will consider that the change in the final energy of the system will be reflected in the work of the system, therefore,
Here,
F = Force
m = mass
v = Velocity
h = Height
d = Distance
Replacing we have,
Therefore the launch energy is 365061ft-lb
Answer:
The capacitance of a parallel plate capacitor is the quantity of charge the capacitor can hold.
This capacitance is proportional to the area of the any of the two plates (if the area of the plates are the same), or the smaller of the two plates (if the plates have different areas) and inversely proportional to the square of the distance of separation (or thickness of the dielectric material) between the plates. It is mathematically expressed as;
C = Aε₀ / d
Where;
C = capacitance
A = Area of one of the plates.
d = distance between the plates
Some of the applications of capacitance (or simply a capacitor) in an electric circuit are;
i. For storage of electrostatic energy.
ii. For filtering and tuning of circuits.
