Answer:
(C) Average Velocity = 25 m/s due North
A. C = 75μF and B. V = 10V.
We have to use the equation k = C/C₀ and k = V₀/V which both are the dielectric constant.
A. The capacitance after the slab is inserted.
With C₀ = 15μF and k = 5.0. Clear k for the equation k = C/C₀:
C = k*C₀
C = (5.0)(15x10⁻⁶F) = 0.000075F
C = 75μF
B. The voltage across the capacitor's plates after the slab is inserted.
With V₀ = 50V and k = 5.0. Clear V from the equation k = V₀/V:
V = V₀/k
V = 50V/5.0
V = 10V
Answer:
2,5 km (2500 meters)
Explanation:
Half of an hour is 30 minutes, so you divide 5/2=2,5
Magnetic force:Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. ... Frictional force:Quite often uses of friction can be seen from how things would be without friction.
