Answer:
C. A spring is stretched.
Explanation:
Kinetic energy is the energy of motion, potential energy is stored energy. The motion of stretching the spring is kinetic, the energy it has before it's released is potential.
Answer:
Explanation:
F = G*m1 * m2 / r^2
G = 6.67408 × 10-11 m3 kg-1 s-2
r = 15 m
F = 4.60 * 10^-6 N
m1 = m2 = m
F = 6.67 * 10^-11 * m^2 / 15^2
4.60 * 10^-6 = 6.67 * 10^-11 * m^2 / 225 Multiply both sides by 225
4.60*10^-6 * 225 = 6.67*10^-11 * m^2
.001035 = 6.67408 × 10-11 * m^2 Divide by 6.67408 × 10-11
0.001035/ 6.67408 × 10-11 = m^2
m^2 = 15507755 Take the square root of both sides
m = sqrt(15507755 )
m = 3938 kg
Answer: Rock candy is candy made of large sugar crystals. To make rock candy, a supersaturated solution of sugar in water is created and left undisturbed for a few days. The driving force behind crystallization is supersaturation.
