Answer:
0.000230144 N
Explanation:
n = Number of electrons =
q = Charge of electron =
k = Coulomb constant =
r = Distance between obects = 1 m
The force would be
The force would be 0.000230144 N
The gravitational force on two objects can be determined by the following equation:
Where G is the gravitational constant m1 is mass 1, m2 is the second mass nad r^2 is distance between these objects. Therefore, let m1 = mass of Sun 1.99x10^30 kg, m2= mass of Jupiter 1.90x10^27 kg, r is the average distance between the Sun and Jupiter 7.78x10^11 m. By plugging these values in we have:
F=4.17x10^23 N
Answer:
Orbital motion
1.is a gravitational motion.
2.they move in the same direction.
3.move are the same time.
Axial motion
1.is a rotary motion
2.move around it own axis
3. revolution takes one year
Answer:
A. The ball has a negative acceleration on the way up and a positive acceleration on the way down.
Explanation:
- When a ball is thrown up vertically then the acceleration due to gravity always acts in a direction towards the center of the earth. So here when an object is thrown vertically upwards then the acceleration due to gravity acting in a downward direction which is opposite to the direction of motion of the object hence taken as negative with respect to the displacement.
- When the ball reaches at the top height its speed becomes zero and then it returns back towards the earth. While coming down the direction of the object's displacement is same as the direction of acceleration due to gravity.
