A object of mass 33 is dropped from a height of 85 meters. Calculate the average power developed by the object in falling throug
DochEvi [55]
Power  =  Work done  /  Time taken.

Work done =  mgh
Mass, m = 33kg    ( Am presuming it is 33 kg).
h =  85 m.
Work done =  33 * 9.81* 85 =  27517.05  J.

Time taken.
Since object was dropped from height, it fell under gravity.
Using    H =  ut  +  (1/2) * gt^2.              u = 0.
               H =  1/2 gt^2.
               t  =   (2H/g) ^ (1/2)
               t  =  (2*85/9.81) ^ 0.5 =  4.1628 s.

Power  =    27517.05 / 4.1628 = 6610.23 Watts.
             =  6610 W  to  3 S. f.

The density of gold is 19.3 g/cm^3. what is the mass of 24 cm^3 of gold?
maw [93]

Mass = Density * Volume

Density = 19.3 g/cm³

Volume = 24 cm³

Mass = Density * Volume = 19.3 g/cm³ * 24 cm³ = 463.2 g

Mass = 463.2 g

The radiations detected by Arno Penzias and Robert Wilson
were the original heat from the Big Bang.

Today, we call those waves the "Cosmic Microwave Background".

I'm not sure, but I think those guys were awarded a Nobel Prize in Physics
for that discovery.
