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.

A hygrometer is an instrument used to measure relative humidity. ... To determine the relative humidity, the temperatures are taken from the dry-bulb thermometer and the temperature difference between the wet and dry bulb thermometers.

hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. There are two main types of hygrometers -- a dry and wet bulb psychrometer and a mechanical hygrometer.

Answer:

1.97*10⁴N .He cannot survive.

Explanation:

The Tidal force can be defined as the difference in force between center of two bodies like center of earth and other bodies.This force stretches the body too and fro from the center of mass of another body due to the difference in the gravitational force.

The tidal force is responsible for various phenomena like ocean tides,celestial body tearing up.

The tidal force is the effect of massive body gravitationally affecting another body.

The tidal force is the difference between the gravitational force of two bodies and directly proportional to the mass of body affecting another body and inversely proportional to the square of radius of the distance between center and the object.

Here let us consider height of person as 2m and d=1m

ΔF= $\frac{GMm}{(R-d)^{2} }$ - $\frac{GMm}{(R+d)^{2} }$

=GMm[ $\frac{1}{(R-d)^{2} }$ - $\frac{1}{(R+d)^{2} }$ ]

=(6.67*10⁻¹¹)(1.99*10³⁰)(1.0)[ $\frac{1}{(300*10^3-1)^{2} }$ - $\frac{1}{(300*10^3+1)^{2} }$ }

ΔF=1.97*10⁴N.

Thus he cannot survive
