All satellite eventually lose their orbital energy and plummet to earth because of______.

Physics
1 answer:
Softa [21]3 years ago

Answer:

gravity

Explanation:

Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity—combined with the satellite's momentum from its launch into space—cause the satellite to go into orbit above Earth, instead of falling back down to the ground.

The planet Mars has much less gravitational force that Earth. What would happen if you went to Mars?
vovangra [49]

gravitational force of planet exerted on its object near the surface is known as weight

so here we know that gravitational force of mars is much less than the gravitational force of Earth

So on the surface of mars the Weight of objects must be much less than the weight of object on surface of Earth

so here correct answer must be

<em>D. Your weight would decrease.</em>

In order to solve this problem, it is necessary to apply the concepts related to the Pressure according to the Force and the Area as well as to the pressure depending on the density, gravity and height.

In the first instance we know that the pressure can be defined as

P = \frac{F}{A}

Where

F= Force

A =  Mass

In the second instance the pressure can also be defined as

P = \rho gh

Where,

\rho=Density of Fluid at this case Water

g = Gravitational Acceleration

h = Height

If we develop the problem to find the pressure then,

P = \frac{F}{A}

P = \frac{F}{\pi r^2}

P = \frac{2*10^6}{\pi (0.1)^2}

P = 6.37*10^{7} Pa

Through the second equation we can find the depth to which it can be submerged,

P = \rho gh

Re-arrange to find h

h = \frac{P}{\rho g}

h = \frac{6.37*10^{7}}{1000*9.8}

h = 6499.4m
