Answer:
F= 10.4 x10^6 N
Explanation:
A/C to Coulomb's law
F = k q1 q2 / r^ 2
F = 9x 10^9 x 2 x 3 / 72^2
F= 10.4 x 10 ^6 N
Answer:
15 V
Explanation:
Electric potential is given as the product of Electric field and distance. Mathematically:
V = E * r
Where E = Electric field
r = distance = 6m
Electric field, E, is:
E = F / q
Where F = Electric force = 5N
q = Electric charge = 2C
Therefore, electric potential will be:
V = (F * r) / q
V = (5 * 6) / 2
V = 15V
Answer:
B. 0.98 m/s
Explanation:
This is because we use the simple formula of dividing the distance by the time. In which case would be 13.69m (distance) divided by 13.92s (time) and we will get 0.983477011 or 0.98m/s (your answer)
I hope this made sense and hoped it helped. Good luck with your test luv :)
Half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.
<h3>
Conservation of energy</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
M.A = K.E + P.E
At the maximum height, the kinetic energy of the ball while potential energy is maximum.
At the half-way down, the ball kinetic energy of the ball is equal to the potential energy.
Thus, half maximum velocity occurs at the point of half maximum kinetic energy which is exactly halfway down.
