Frequency = (speed) / (wavelength) = 20 / 0.5 = 40 per second = 40 Hz.
Since this situation can be thought of as a direct variation. multiply 20000 with 100 and divide the product with 1500.
Answer:
Major, weight-bearing structures are the bones of the body that are strong and dense to be able to bear the weight of the body. The major, weight-bearing structures of cat and human skeletons are :
Human skeleton: The body weight of an individual is on his pelvic girdles that are attached to the bones of lower limbs. Thigh bones, leg bones, and bones of feet comprise lower limbs The lower limbs consist of the thigh, the leg, and the foot.
Cat skeleton: cats are quadrupedal so it bears all the body weight on shoulders and legs that includes the Scapula and pelvis.
Answer:
The feeling of weight is one of compression.
Explanation:
All your body is being pulled down by gravity yet your feet ( if standing) or your back or something is holding you up.
Your body is compressed by the PAIR of forces and it is that compression that you feel.
So when you remove the supporting force then all the body is free to move together and there is no compression within you.
Hence you perceive no weight.
