Marysya12 [62]

Answer:

1.97*10⁴N .He cannot survive.

Explanation:

The<em> </em><em>Tidal force</em> 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

Give two examples of how magnetic domains and electric charges are similar
zhannawk [14.2K]
The fundamental closeness is they have a similar like charges repulse each other, distinctive charges pull in each other. While their distinction is that attractive "charges" can't be isolated. At any rate, so far it has not been accomplished. I trust this makes a difference.

A transverse wave is set up in a very long string. The oscillator is set at 20.0 Hz, and the wave speed is 78 m/s. The amplitude
Sedbober [7]

To solve this problem we must apply the concepts related to Tangential Acceleration based on angular velocity and acceleration, and therefore, we must also calculate angular velocity based on the given frequency. For all these problems we will take the Units to the International System. The maximum acceleration would then be defined as,

a_{max} = \omega^2 A

Here,

\omega= Angular velocity

A = Amplitude

At the same time the angular velocity is described as,

\omega = 2\pi f

Here f means the frequency of the wave. Substituting,

\omega = 2 \pi (20)

\omega = 40\pi

A = 5.2cm

A = 0.052m

Replacing at the first equation,

a_{max} = (40\pi )^2 (0.052)

a_{max} = 821.15m/s^2

Therefore the maximum particle acceleration for a point on the string is 821.15m/s^2
