The Milky Way is a spiral and most smaller galaxies are large clouds. We also have a supermassive black hole in our core, most spiral galaxies have one.
Choice-D is the only velocity on the list.
(It has a speed and a direction.)
Given:
m = 5.00x10^-7 kg
q = 3.00<span>μC
To determine the velocity, use this formula
</span>
v = √(2qΔx/m)
Now, solve for the velocity, substitute the given values to the equation
v = √(2(3.00μC * 0.600m/5.00x10^-7 kg)
Solve for V and this is the velocity of your sphere in condition 1. <span />
<span>A jet of water issuing from a stationary nozzle at 15.3 m/sec (Aj = 0.03 m2) strikes a turning vane mounted on a cart as shown. The vane turns the jet through an angle = 60o. Determine the value of M (in kg) required to hold the cart stationary.</span>
