The Sun keeps the planets in orbit, using it's own gravitational pull. IT also powers every planet, allowing plants to thrive and people to live.
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.

To change from mass to weight is Fw = 30 kg * 9.8 m/s^2 = 294 N. To change from weight to mass divide by gravity (9.8 m/s^2).
Newton's First Law of Motion:
I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
Newton's Second Law of Motion:
II. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.
Newton's Third Law of Motion:
III. For every action there is an equal and opposite reaction.
Answer:
Explanation:
From this exercise, our knowable variables are <u>hight and initial velocity </u>
To find how much time does the <u>ball strike the ground</u>, we need to know that the final position of the ball is y=0ft
Solving for t using quadratic formula
or
<u><em>Since time can't be negative the answer is t=6.96s</em></u>
