The Doppler effect determined and supported that the universe was expanding by measuring the Doppler effect in the light emitted from galaxies.
Hope this helps!
Answer:
Yes, there is such a way.
Explanation:
If currents flow in the same direction in two or more long parallel wires, there will be an attractive force between the wires. If the current flows in different directions, there will be a repulsive force between the wires. In this case, these three parallel wires, can be be made to carry current in the same direction, creating an attractive force between all three wires.
Note that it is not possible to have at the least one of them carry current in the opposite direction and still have an attractive current between them.
Answer:
F = k q1 q2 / r^2
r^2 = k q1 q2 / F = 9E9 * 4E-5 * 10.8E-5 / 4
r^2 = 9 * 4 * 10.8 / 4 * E-1 = 9.72 m^2
r = 3.12 m
Answer:
52.5m/s
Explanation:
u=45km/hr=45×1000/60×60=12.5
t= 5 sec
a=8m/s^2
v=?
Now,
v=u+at
v=12.5+8×5
v=52.5
