Answer:
k = 22.05 N/m
Explanation:
The potential energy of the mass is converted into potential energy of the spring.
Given:
mass m = 0.27 kg
gravitational constant g = 9.8 m/s²
distance falling/ stretching of spring h = 0.24 m
Solving for k:
Answer:
A. 10 N
B. 20 N
C. 1,000 N
Explanation:
D. According to Newton's Third Law, in the simplest terms, each and every action (force) has an equal but opposite reaction. So when the air pushes out to the left, the pressure of the air being released propels the balloon to the right. Therefore, Newton's Third Law is followed in this scenario. That is the same case for the above three questions as well.
When all the lights are in series, and any one of them burns out
or is pulled out, or the wire between the lights is cut anywhere,
ALL the lights go out.
If all the lights were in parallel, then they're totally unaware of each
other, and the loss of any single light has no effect on the others.
