Answer:
142.296 Nm.
Explanation:
Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Nm.
From the question,
T = F×r.................... Equation 1
Where T = Torque, F = Force, r = radius of the circle.
Note: F is the weight of the bicyclist.
Then,
F = W = mg............... Equation 2
Substitute equation 2 into equation 1
T = mgr................... Equation 3
Given: m = 88 kg, g = 9.8 m/s², r = 0.33/2 m
T = 88(9.8)(0.33)/2
T = 142.296 Nm.
A sprain is a stretch and/or tear of a ligament. It would cause pain but wouldn't actually dislocate anything. It's not the most painful injury, it can be healed, and stretching would help but not completely avoid a sprain. So that's why D is the answer.
Refraction. refraction is always accompanied by a wavelength and speed change
4.8m/s2 according to the formula F=MA
