A mixture is made of (elements).
The answer would be erin out of all of them thank me later :)
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.
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.
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.= 
ω =2 π x 
ω² = 4π² x T/γ²μ}
For weightlessness
ω² A = g
A= g x γ²μ / 4π² T
