Answer:
"The properties of magnets are used to make electricity. ... Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy."

Answer:
480 mL
Explanation:
Ideal gas law states:
PV = nRT
At constant pressure, nR/P is constant. Therefore:
V / T = V / T
420 mL / 220 K = V / 250 K
V ≈ 480 mL
Answer:
Explanation:
The force that one atom exerts on the other is the negative derivative of the potential energy = 
F(x) = - 
( -C₆ / x⁷) = - (- (-6) C₆ x⁻⁶ ⁻¹) = - 6C₆ /x⁷
when xis negative, F is positive and when x is positive, F is negative. It is therefore and attractive force and F is always directed to the center
Answer:
∆PE = 749.7 J
At 0.9 m high, PE = 793.8 J
At 1.75 m high, PE = 1543.5 J
