Explanation:
a chemical change is the only change that can change a substance since it changes the chemical properties of the substance, hence making a new substance

Because they want attention
Answer:4.39 s
Explanation:
Given
initial velocity
acceleration
velocity acquired by sled in time
distance traveled by sled in
distance traveled in time with velocity
----1
substitute the value of in 1
we get
thus
If total charge Q is enclosed in the surface of cube
then we will have say that total flux linked with all surfaces of the cube will be given by
since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube
So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces
so flux linked with each face is given by formula
so each face will have above flux due to central position of charge Q
