Answer:
They are orbiting earth.So they stay in orbit.
We know that gravity increases with height.
Explanation:
1st Question Explanation:
- Earth's gravity still pull on them.
- Gravity combines with the satellite's momentum from its launch into space.This Combination cause the satellite go into the orbit.
2nd Question Explanation:
- Gravity is caused by the Earth's spinning
- Gravity is notable bless on high mountains or tall buildings.
Can be absorbed and transformed into heat. i know this because i used to work as a constructor for lights and i had to go over a training on this subject.
The correct option is (b) 5n
As a result, there is a net downward force of 5N operating on the object.
The resultant force is the force that results from adding the vector sums of all the forces operating on an item. The combined action of all the acting forces on the object produces the same effect as the resulting force. When determining the resulting force, the direction of the forces must be taken into account.
Given;
The northward force is Fn = 10N
The southward force is Fs = 15N
Required;
The net force on the mobile phone is Fnet = ?N
The object's weight exerts downward pressure, and upward resistance exerts upward pressure. The vector sum of these two forces will be the net force.
Fnet = Fs - Fn (Considering the direction downward as positive)
Fnet= 15N - 10N
Fnet = 5N
As a result, there is a net downward force of 5 N operating on the object.

Answer:
50 Ohms
Explanation:
Given that
the original resistance of the wire is 2 ohms, then
it is known that the equivalent resistance in a parallel circuit is
1/R(eq) = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5.......+ 1/Rn
Giving that there are 5 pieces, then we stop at number 5.
Since R(eq) is 2, we substitute for that, and then we have
1/2 = 1/R + 1/R + 1/R + 1/R + 1/R
1/2 = 5/R
R = 5 * 2
R = 10 ohms
Since each R is 10 ohms, and the wire was cut into 5 pieces, we can then say that the original resistance of the wire is
R + R + R + R + R
10 + 10 + 10 + 10 + 10
total original resistance is 50 Ohms
