answer is
Explanation:
average power each panel produces = 21700/ 5×10^6
4340 ×10^-6
that's mean 4340 micro Watt
Answer:
Explanation:
Radius of circular path of coin R = 12.5 x 10⁻²,
coefficient of static friction μs = .33
In order that the coin rotates in circular path , it requires centripetal force which is provided by friction. As speed of rotation increases , force of friction also increases to provide it required centripetal force. When the speed of rotation becomes too high so that frictional force can not compensate the increase in centripetal force then coin will start slipping or it starts moving with respect to turntable.
b ) At this point of time
centripetal force = limiting force of friction
mω² R = μs mg , m is mass of the coin , ω is angular velocity ,
ω² R = μs g
ω² x 12.5 x 10⁻², = .33 x 9.8
ω² = .33 x 9.8 / 12.5 x 10⁻²,
= 25.87
ω = 5.08 rad / s
2π / T = 5.08
T = 2π / 5.08
= 1.23 s .
Answer:
m = 47.5 Kg
Explanation:
given,
speed of skater toward north, v = 0.8 m/s
momentum of the skater in north, P = 38 Kg.m/s
mass of the skater = ?
we now,
Momentum is equal to the product of mass and velocity
P = m x v
38 = m x 0.8
m = 47.5 Kg
hence, mass of the skater is equal to 47.5 Kg.
Answer:
Explanation:
we know angular velocity in terms of moment of inertia and angular speed
ω .... (1)
moment of inertia of rod rotating about its center of length b
........ .(2)
using v = ωr
where w is angular velocity
and r is radius of rod which is equal to b
so we get 2v = ωb
ω = 2v/b ................. (3)
here velocity is two time because two opposite ends are moving opposite with a velocity v so net velocity will be 2v
put second and third equation in ist equation
×
so final answer will be
The answer is Open Circuit. Open Circuit is a circuit that has a break that prevents the flow of current; a circuit with a gap that stops the current. An "open<span>" (off) switch leave gaps in a </span>circuit<span> preventing electrons from traveling from one side of the power source to the other. Thus, electrons will not flow. This situation is called an </span>open circuit<span>.</span>
