Answer:
The correct answer would be B) Scalar
It has a diameter of about 78 billion miles. For perspective, that's about 40% the size of our solar system, according to some estimates. And it's estimated to be about 21 billion times the mass of our sun. So there you have it, black holes can be millions of times larger than suns and planets or as small as a city.
It would take the bicyclist 9 seconds to move 36m.
The electric potential at point b experienced by the charge cab be determined using the formulas given.
<h3>Electric potential</h3>
The electric potential of a point charge is the work done in moving the charge from infinity to certain point against the electric field.
V = Ed
V = (F/q)d
V = (Fd)/q
where;
- V is the electric potential
- F is electric force
- E is the electric field
- q is the charge
Thus, the electric potential at point b experienced by the charge cab be determined using the formulas given.

Tension in the rope due to applied force will be given as
angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done
now we can plug in all values above
So here work done to pull is given by 691.8 J
