Answer:
a = 0.098 m/s²
Explanation:
The satellite, at any distance from the center of the Earth, is subject to the attractive force due to the Earth, according to the Newton´s Universal Law of gravitation, as follows:
Fg = G*ms*mE / (rse)²
According to Newton´s 2nd Law, neglecting any other force acted upon the satellite, we can write the following equation:
Fg = ms*a = G*ms*mE / (rse)²
⇒ a = G*mE / (rse)² (1)
As the distance between the satellite and the center of the Earth is 10 times the radius of the Earth, replacing this value in (1), we have:
a = G*mE / (10*RE)² = G*mE/(RE)² * (1/100)
but G*mE/(RE)², is just g, the acceleration due to gravity on the surface of the earth, so the gravitational acceleration due to Earth at satellite A, is as follows:
a = g*(1/100) = 0.01*g = 0.098 m/s²
Firstly, when we say precision, this means the level of detail of a number. On the other hand, significance means that how precise a number is written and accuracy is defined as how close the number is to an actual value. Significant figures represent the precision of a measurement and not its accuracy because when a measurement has a larger number of significant figures, it has a greater reproducibility <span>or precision because it has a smaller source of error in the estimated digit. Hope this answer helps.</span>
2,200 Newtons.
F = ma
v f = v i + at
0mls = 20mls + a(.5s)
-20mls/.5s = -40mls squared
-40mls squared (55kg) = 2,200 Newtons.
Hope this helps!
Answer:
Force, 
Explanation:
Distance between proton is 0.005 m
It is required to find the force between two protons. Protons have of positive charge of 
. Two protons will have a force of repulsion between them. The force is given by :
So, the force between two protons is 
.
