Solids have a defined shape and liquids don't.
Answer:
a) 4.6*10^{-5} J
b) 6133.33 J/C
c) 94358.9 C
Explanation:
(a) We have that the change in the kinetic energy equals the net work over the charge. Hence we have
where Ek is the kinetic energy, W is the work of the external force and WE is the work done by the electric field. By replacing we obtain:
(b) The potential difference is computed by using:
(c) With the work done by the electric force we can calculate the Electric field. By using the following formula we obtain:
where we have used d=6.5cm=6.5*10^-9m and q=7.5nC=7.5*10^-9C
hope this helps!!
Answer:
Triton orbits Neptune in what is known as a retrograde orbit. This means that it orbits Neptune a direction opposite the planet's rotation. ... Others think that Triton may have been formed elsewhere and then captured by Neptune's gravity.

Answer:
v_f = 1.14 m / s
Explanation:
This is an exercise of conservation of momentum, let's define a system formed by the skater and the snowball, therefore the forces during the launch are internal and the moment is conserved.
Initial instant. Before throwing the ball
p₀ = M v₀
Final moment. After throwing the snowball
p_f = (M-m) v_f + m v
the moment is preserved
p₀ = p_f
M v₀ = (M-m) v_f + m v
v_f =
let's calculate
v_f =
v_f = 64.936 / 56.89
v_f = 1.14 m / s
