Answer:

Upward
Explanation:
We are given that
Mass of scarp paper,
1mg=
Distance,d =8 mm=
Magnitude of electric force =
Where 
Substitute the values


Gravitational force act in downward direction.
The electric force acts in opposite direction and magnitude of electric force is equal to gravitational force.
Hence, the direction of electric force is upward.
Sound spreads through some kind of medium. Most of the time the medium is usually air. Sound can go through walls, like when you are playing really loud music and the neighbors tell you its to loud, you can't block it because it can travel through objects. Light does not need a medium to travel with. if you put a light in a room with no windows and no cracks, and you seal off the door the light can't escape that room, but if you did the same thing with sound it would travel trough the walls.
We know, F = m.a
Here, m = 1.5 Kg
a = v/t = 2/0.3 = 6.67 m/s
Substitute their values,
F = 1.5 * 6.67
F = 10 N
In short, Your Answer would be 10 Newtons
Hope this helps!
Explanation:
According to newtons first law of motion " A body is at a state of rest or uniform motion unless acted upon by a force (external)" which will either
1. change the direction
2. change the acceleration
3. change the velocity(moves or stop the body from moving)
4. change the shape or size
Answer:
B
Explanation:
to see how fast she is going per second, you would have to divide the distance traveled by the seconds it took to travel the distance
