The acceleration that the net force will cause is 7.5 m/s²
To solve this problem, first, we need to find the net force.
⇒ Equation:
F = ma................ Equation 1
⇒ Where:
- m = mass of the box
- a = acceleration of the box
From the question,
⇒ Given;
⇒ Substitute these values into equation 1
We also use the same equation 1 to find the acceleration that the net force will cause to a box of mass 2.8 kg.
⇒ make a the subject in equation 1
- a = F/m................. Equation 2
⇒ Substitute the appropriate values into equation 2
Hence, The acceleration that the net force will cause is 7.5 m/s²

1. Is A. at the poles because thats where the magnetic field is going out then coming back into the earth to produce the magnetic field.
2. Again its A. because the compass needle is attracted to " north " which is magnetic south. It does this because opposites attract.
3. This one would be B. Because if the magnets were being repelled the magnetic field lines would look like there was a line that the field hit and bounced off of it.
4. This answer is A. the magnetite helps them migrate so they know which way is north and which way is south.
5. This answer is A. Because without the domains there wouldn't be poles on the magnetic object. <span />
Answer:
D. Output force
Explanation:
The input force is the effort used to run the machine and this results in an output force.
It affects basketball in a way called traction.
The friction between the players' basketball shoes and the hard wooden floor is traction, or friction. Without it, players would slide everywhere and wouldn't be able to play the game.
Answer:
.
Explanation:
If the mass of an object is 
and the velocity of that object is 
, the linear momentum of that object would be 
.
Assume that the initial velocity of the mass is positive (
.) However, the direction of the velocity is reversed after the impact. Thus, the sign of the new velocity of the object would be negative- the opposite of that of the initial velocity. The new velocity would be 
.
Thus, the change in the velocity of the mass would be:
.
The change in the linear momentum of the mass would be:
.
Thus, the magnitude of the change of the linear momentum would be 
.
