Question

If the entire population of China jumped at the same time would this cause a tidal wave or similar?

Answer 1

No

Answer 2

Let's figure it out.

An average Chinese weighs 70kg.

There are 1.4 billion Chinese.

China's area is 10 million sq.kms. (10 trillion sq.m.)

'g' = 9.8 mtr/sec/sec = rounded to 10m/s^2.

Total 'mass' of the nation=1.4 X 70= 100 bil. kg

Force generated by a synchronous jump= 1 trillion N

Pressure= force/area

=1 tril N/10 tril m^2

=(1/10) pascals.

This is nothing; 1Atm=10kP in comparison.

I think that settles it!

Answer 3

No.  The weight of the entire human race is only a trillionth of the weight of the earth.  If all humanity jumped at the same time, it would have a negligible effect.  There are some very sensitive seismographs however, that would be able to record it.

Answer 4

Yeah we would all be wiped out of course. The effect would very similair to a meteor crashing into the earth.

Answer 5

A tidal wave isn't just a big wave, it is actually caused by tides, hence the name. What you are thinking of is a tsunami. Anyway to answer the question I would have to say no.

Answer 6

lol funny question.

Answer 7

Imagine if they all farted at the same time

Answer 8

No, But it would probably create a huge 'c***k' in the earth's crust!
