Afterdrop is the phenomenon of your body temperature continue to drop even after you get out of cold water and into a warmer environment – so that you feel colder 10 or 40 minutes after you exit than you did in the water. When you swim, your body shuts down circulation to your skin, pooling warm blood in your core.
Answer:
Both Vitamin D and folate level are affected by UV radiation from sunlight.
Explanation:
Given,
Mass of the ball (m) = 1.50 x 10³ kg = 1500 kg
Height raised = Displacement of the ball (D) = 40.0 m
Time taken (t) = 20 seconds
Power = Work done(W) ÷ time taken (t)
Work done (W) = Force (F) x Displacement (D)
Force (F) = Mass (m) x Acceleration due to gravity (g)
Acceleration due to gravity for earth (g) = 9.81 m/s²
Therefore,
Force (F) = 1500 x 9.8 = 14715 N
Work done = Force x Displacement = 14715 x 40 = 588600 Joules
Now,
Power = Work done ÷ time taken = 588600 ÷ 20 = 29430 Watts
