EPE= 0.5 * spring constant * (extension)^2
Spring constant=EPE/0.5*extension^2
5J/0.5*0.5^2
=40N/m
The answer would be machines
Answer:
C. Ce2(so4)3
Explanation:
A gas will escape from water as the temperature increases. Solubility is the characteristic of staying dissolved in the water.
Answer:
56.25 watts
Explanation:
P = F * d / t
P = Power (it's an unknown at this point).
F = 450 N
d = 25 steps each 10 cm = 25 steps 0.1 m/step = 2.5 m
t = 20 s
Solution
P = 450 * 2.5 / 20
P = 1125/20
P = 56.25
