To solve this problem we will apply the concepts related to Orbital Speed as a function of the universal gravitational constant, the mass of the planet and the orbital distance of the satellite. From finding the velocity it will be possible to calculate the period of the body and finally the gravitational force acting on the satellite.
PART A)
![V_{orbital} = \sqrt{\frac{GM_E}{R}}](https://tex.z-dn.net/?f=V_%7Borbital%7D%20%3D%20%5Csqrt%7B%5Cfrac%7BGM_E%7D%7BR%7D%7D)
Here,
M = Mass of Earth
R = Distance from center to the satellite
Replacing with our values we have,
![V_{orbital} = \sqrt{\frac{(6.67*10^{-11})(5.972*10^{24})}{(6370*10^3)+(6370*10^3)}}](https://tex.z-dn.net/?f=V_%7Borbital%7D%20%3D%20%5Csqrt%7B%5Cfrac%7B%286.67%2A10%5E%7B-11%7D%29%285.972%2A10%5E%7B24%7D%29%7D%7B%286370%2A10%5E3%29%2B%286370%2A10%5E3%29%7D%7D)
![V_{orbital} = 5591.62m/s](https://tex.z-dn.net/?f=V_%7Borbital%7D%20%3D%205591.62m%2Fs)
![V_{orbital} = 5.591*10^3m/s](https://tex.z-dn.net/?f=V_%7Borbital%7D%20%3D%205.591%2A10%5E3m%2Fs)
PART B) The period of satellite is given as,
![T = 2\pi \sqrt{\frac{r^3}{Gm_E}}](https://tex.z-dn.net/?f=T%20%3D%202%5Cpi%20%5Csqrt%7B%5Cfrac%7Br%5E3%7D%7BGm_E%7D%7D)
![T = \frac{2\pi r}{V_{orbital}}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2%5Cpi%20r%7D%7BV_%7Borbital%7D%7D)
![T = \frac{2\pi (2*6370*10^3)}{5.591*10^3}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B2%5Cpi%20%282%2A6370%2A10%5E3%29%7D%7B5.591%2A10%5E3%7D)
![T = 238.61min](https://tex.z-dn.net/?f=T%20%3D%20238.61min)
PART C) The gravitational force on the satellite is given by,
![F = ma](https://tex.z-dn.net/?f=F%20%3D%20ma)
![F = \frac{1}{4} mg](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B1%7D%7B4%7D%20mg)
![F = \frac{270*9.8}{4}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B270%2A9.8%7D%7B4%7D)
![F = 661.5N](https://tex.z-dn.net/?f=F%20%3D%20661.5N)
Answer:
speed and time are Vf = 4.43 m/s and t = 0.45 s
Explanation:
This is a problem of free fall, we have the equations of kinematics
Vf² = Vo² + 2g x
As the object is released the initial velocity is zero, let's look at the final velocity with the equation
Vf = √( 2 g X)
Vf = √(2 9.8 1)
Vf = 4.43 m/s
This is the speed with which it reaches the ground
Having the final speed we can find the time
Vf = Vo + g t
t = Vf / g
t = 4.43 / 9.8
t = 0.45 s
This is the time of fall of the body to touch the ground
According to Newton's second law
E.e = a * mp ..... (1)
where
E is the magnitude of the electric field; e = 1.6 * 10^-19 is the elementary charge; mp = 1.67*10^-27 kg is the proton mass; a is the acceleration.
So, the distance
l = at^2/2 .......(2)
The proton accelerated
a = 2l / t^2 ...........(3)
From equations (1) and (3)
E= 32.51 V/m
Electric field
The physical field that surrounds electrically charged particles and exerts a force on all other charged particles in the field, either attracting or repelling them, is known as an electric field (also known as an E-field). It can also refer to a system of charged particles' physical field. Electric charges and time-varying electric currents are the building blocks of electric fields. The electromagnetic field, one of the four fundamental interactions (also known as forces) of nature, manifests itself in both electric and magnetic fields.

Answer:
Answer:
D) by using military force.
Explanation:
Typically, people like Mussolini and Stalin gain popularity in trying times by promising a type of well-being to a group or nation of stricken people, in which they gain huge amounts of popularity at once. Typically they are then elected to some seat of power, in which, with popularity and most likely the military on their side, they would overthrow the current government. The next step taken is to suppress any opposition or even those who don't fully support the party. This can be given out in two ways, which is through force (especially opposition), or providing benefits to those who are in the party (to draw those who are not exactly supporting to support for the benefits).
With "popular" support, as well as military control, the overthrow is complete, and the group is established in power.
