It runs slower <span>as gravity is lower so acceleration due to gravity is smaller</span>
Answer: The distance between the man and the plane increasing at a rate of 400ft/s
Explanation: Please see the attachments below
Answer:
27 cm
Explanation:
ASSUMING the elevator is in a constant velocity state (could be zero)
mg = kx
x = mg/k = 15(9.8)/550 = 0.267272... m ≈ 27 cm
Answer:
The 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
Explanation:
The standard temperature at sea level is 15 degrees Celsius. It decreases about 2 degrees C (or 3.5 degrees F) per 1,000 feet of altitude above sea level.
235 meters is equal to 771 feet.
Using the formula below, we can estimate temperature loss due to this change in altitude, that is 771 feet above sea level.
temperature loss = (3.5 x Change in altitude)/1000ft
temperature loss = (3.5 x 771ft)/1000ft = 2.7⁰F, (32 -2.7 = 29.3 ⁰F)
this is equivalent to 1.5⁰C temperature loss.
Thus, the standard temperature of the engineering quadrangle at 235 meters above sea level is 13.5 ⁰C.
Therefore, the 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
