Answer: Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.
Explanation:
This question is asking the force on the rope. We can find this by using centripetal acceleration, then multiply by the ice skater's mass.
First we need to find the centripetal acceleration, which is a = v^2/r
We are given v and r, so we solve for a.
a = [(5.14m/s)^2]/(0.525m) = 50.323 m/s^2
Next multiply by the ice skater's mass (because F=ma) which is 44.6 kg
We then get F = (50.323m/s^2)(44.6kg) = 2244.407924N
Divide by 10^3 to get kN, we get:
2.244kN
Hope this helps!
Since the equation for frequency is:
frequency = velocity/wavelength, then the correct answer is B. velocity.
In order to calculate the velocity, we just need to multiply frequency and wavelength.
