A capacitor is connected to an ac generator. As the generator’s frequency is increased, what happens to the capacitor connected
Bad White [126]

Answer:

Current in the capacitor increases as the frequency of the generator increases

Explanation:

Xc = 1/2πfC = 1/ wC

Since frequency is inversely proportional to reactance of a capacitor,

as the frequency increases, the capacitance decreases and tend towards behaving like a wire with zero resistance as such the generator send high current to the capacitor, the current in the capacitor increases.

A car is travelling at 36 km per hour if its velocity increases to 72 km per hour in 5 seconds then find the acceleration of car
velikii [3]

Answer:

36 km /h means 10 m/s. Increase in speed is 10m/s in 5 s . Acceleration is ( 10/5 ) = 2 m/s^ 2.

A large ant is standing on the middle of acircus tightrope that is stretched with tension Ts. The rope has mass per unit length
77julia77 [94]

Answer:

Explanation:

The ant , at some point of time will be standing on the crest of moving wave passing under its feet . At that position the downward acceleration of the ant will be equal to its weight . Hence it will feel weightlessness . So at that time

Acceleration = g

Acceleration at the top position = ω²A where ω is angular velocity and A is amplitude of vibration ( transverse ) of crest .

ω =2 π n where n is frequency of transverse vibration of particles. This angular frequency will be equal to angular  frequency of wave travelling on the rope .

frequency  of travelling  wave

n.= \frac{1}{\gamma}\sqrt{\frac{T}{\mu} }

ω =2 π  x \frac{1}{\gamma}\sqrt{\frac{T}{\mu}

ω² = 4π² x T/γ²μ}

For weightlessness

ω² A = g

A= g x γ²μ / 4π² T
