Answer:
Electric field will remain same.
Explanation:
Given that
At initial condition ,charge q = +3μ C
Electric field E = 4106 N/c
As we know that
Electric field due to charge q
Now when charge is replaced by new charge q'= -3μ C
From the expression of electric field we can say that electric field will remain same from same quantity of electric charge.
So we can say that electric field will remain same.
Answer:
a. Glass is denser than wood.
Explanation:
Density=Mass/volume
In this case we know that mass of glass is greater than wood. And the volume of both glass and wood are the same, so we will ignore that factor. Since mass is directly proportional to density, if your mass increase, your density increases as well, in this case.
C. Surface.

Answer:
Explanation:
Given
First bicycle travels 6.10 km due to east in 0.21 h
Suppose its position vector is 
After that it travels 11.30 km at 
east of north in 0.560 h
suppose its position vector is 
after that he finally travel 6.10 km due to east in 0.21 h
suppose its position vector is 
so position of final position is given by
t=0.21+0.56+0.21=0.98 h
For direction
w.r.t to x axis
Answer: C
Explanation:
Energy stays the same, but there’s more kinetic energy the less it moves and mor kinetic energy the more it moves
