What would happen to the brightness of the bulb in the following circuit as I increase the resistance of the variable resistor?

Explain your answer

As you crank the variable resistor to higher resistance, the total current in the loop decreases.  The power dissipated by the light bulb ... the heat and brightness it produces ... depend directly on the current through it, so they decrease too.  Your circuit is a perfect incandescent light dimmer circuit.

VLD [36.1K]

Answer:

0.22 m

Explanation:

m = 0.43 kg, K = 561 N/m

Vmax = 8 m/s

Let the amplitude of the oscillations be A.

The formula for the angular frequency of oscillation sis given by

\omega  = \sqrt{\frac{K}{m}}

\omega  = \sqrt{\frac{561}{0.43}}

ω = 36.1 rad/s

The formula for the maximum velocity is given by

Vmax = ω x A

A = Vmax / ω

A = 8 / 36.1 = 0.22 m

__________ curves help lessen the effect of the force of the forward motion on your vehicle as it enters the curve.
Rainbow [258]

Answer:

Banked

Explanation:

Banked curves are formed when the inner edge is below the outer edge.

It is done in order to ensure the reliability of the frictional force as it varies when the road is wet wet or oily. Thus in order to avoid these problems the curved roads are banked.

Banking of the curve provides the necessary centripetal force, i.e., the horizontal component of the normal reaction force to keep the vehicle i motion and thus helps in reducing the effect of the forward motion force on the vehicle.
