Answer:


Inclined Plane


Explanation:


An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines.


The basic principle of Inclined pane is as follows


W = F x D ( Force times Distance)


where W shows the word done.

How are force and mass related​
11Alexandr11 [23.1K]

<em>Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.</em>

A geosynchronous satellite orbits Earth at a distance of 42,250 km from the center of Earth and has a period of 1 day. What is t
yan [13]

Answer:

The centripetal acceleration of the satellite is a=0.22\ m/s^2.

Explanation:

Given that,

The distance covered by a geosynchronous satellite, d = 42250 km

The time taken by the satellite to covered distance, t = 1 day = 24 hours

Since, 24 hours = 86400 seconds

Let v is the speed of the satellite. It is given by the total distance divided by total time taken such that :

v=\dfrac{d}{t}

v=\dfrac{2\pi d}{t}

v=\dfrac{2\pi\times 42250 \times 10^3}{86400 }

v = 3072.5 m/s

The centripetal acceleration of the satellite is given by :

a=\dfrac{v^2}{d}

a=\dfrac{(3072.5)^2}{42250 \times 10^3}

a=0.22\ m/s^2

So, the centripetal acceleration of the satellite is a=0.22\ m/s^2. Hence, this is the required solution.
