Well, an electromagnetic wave can pass through a vacuum of space and examples of that is lasers. so the correct answer is A.Lasers.
The answer is D
This is an example of Newton's third law of motion.
The active force is the fish against the water, so the reactive force would be the reverse, the equal force of the water on the fish.
Answer:
Explanation:
F = ma
mgsinθ - μmgcosθ = ma
gsinθ - μgcosθ = a
μgcosθ = gsinθ - a
μ = (gsinθ - a) / gcosθ
μ = (9.81sin24 - 0.245) / 9.81cos24
μ = 0.4178906...
μ = 0.418
V = 0, a increasing
a = 0
v increasing, a increasing
v decreasing, a decreasing
