Answer:
Explanation:
When the central shaft rotates , the seat along with passenger also rotates . Their rotation requires a centripetal force of mw²R where m is mass of the passenger and w is the angular velocity and R is radius of the circle in which the passenger rotates.
This force is provided by a component of T , the tension in the rope from which the passenger hangs . If θ be the angle the rope makes with horizontal ,
T cos θ will provide the centripetal force . So
Tcosθ = mw²R
Tsinθ component will balance the weight .
Tsinθ = mg
Dividing the two equation
Tanθ = 
Hence for a given w , θ depends upon g or weight .
The answer is false because there are single celled organisms.
Answer:
The equation of current is 
Explanation:
Resistance, R = 12 ohm
Inductance, L = 0.06 H
E (t) = 12 cos (120 t)
Compare with the standard equation,


So, the inductive reactance is
XL = w L = 120 x 0.06 = 7.2 ohm
The impedance of the circuit is

The current leads by 90degree so the equation of current is

The answer to your question is Protons!
