Answer-A
The water cycle shows how water moves around earth.
Ex: Runoffs,precipitation, condensation, evaporation.
-Steel jelly
Let <em>b</em> be the height of the building, and <em>y</em> the height of the ball at time <em>t</em>, given by
<em>y</em> = <em>b</em> - 1/2 <em>gt</em>²
where <em>g</em> = 9.8 m/s² is the magnitude of the acceleration due to gravity.
It takes the ball 8 s to reach the ground, at which point <em>y</em> = 0, so that
0 = <em>b</em> - 1/2 (9.8 m/s²) (8 s)²
<em>b</em> = 1/2 (9.8 m/s²) (8 s)²
<em>b</em> = 313.6 m
Answer:
The magnetic force on the moving negative charge is towards the ceiling.
Explanation:
The magnetic force acting on a wire is given by the relation as follows :

q is charged particle
v is velocity of charged particle
B is magnetic field
In this case, a negative charge is moving across a rook from south to north. A magnetic field runs from East to west.
q = -q
v =+j
B = -i
So,

Since, 
So,

So, the magnetic force on the moving negative charge is towards the ceiling.
