F = ma (force = mass x acceleration)
So the car’s mass affects the amount of force, changing how it would roll down a ramp, I think.
Answer:
A cell is the basic block of life and is always changing to fit its environment.
Explanation:
A cell is the basic founding block of a living organisms. In other words, a cell is the basic membrane unit which contains fundamental molecules of life. It is the cell that all living things are composed of.
The cell always changes with the surroundings and environment and it adapts to it. The cells requires a constant adjustments as the conditions inside and the outside the cells changes to keep a stable internal environment. Because the environment internally and externally is always changing, the cell continuously make adjustments to stay at or the near the set point.
mass x velocity which equals to ML/T
Answer:
50 degrees
Explanation:
Usually in physics in solving such questions refractive index of air is taken as 1.00 (n=1.00) by assuming that air is a vacuum. Hence, the light ray passes from water to air at an angle of incident of 40 degrees, it means that it has angle of 50 degrees to the normal line.
Answer:
K = 109.1 N/m
Explanation:
From the question, the following parameters are given.
Extension e = 55 m
Force F = 6000N
According to Hooke's law,
F = Ke
Where K = spring constant.
Substitute F and e into the formula and make K the subject of formula.
6000 = K × 55
K = 6000/55
K = 109.1 N/m
Therefore, the spring constant of a bungee cord that stretches is 109.1 N/m
