In motion on an inclined experiment, a student measures the angle of inclined plane with a protractor whose uncertainty is Δθ=1 The acceleration of the motion due to gravity g along the inclined plane, which is has uncertainty due to the uncertainty of measuring the angle. Which one of the following is true about the uncertainty of acceleration Δa? a. Δa= gSinθ x Δθ
b. Δa= gCosθ x Δθ
c. Δa= gTanθ x Δθ
d. Δa= gSinθ

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
