Answer:
Part a)
Part b)
U = 111 J
Explanation:
As we know that the capacitor is of capacitance
now the maximum charge on it
Part a)
Oscillation frequency of the charge is given as
Part b)
Now the equation of charge oscillation is given as
now current in the circuit is given as
now at t = 1.35 ms we have
So the energy stored in inductor is given as
Answer:
346.01 × 10² Lux
Explanation:
Given:
luminance of the sun at zenith at sea level, Ls = 1600 × 10 cd/m²
The diameter of the sun's photosphere = 8.64 × 10 miles = 45.62 × 10⁸ ft
or
Radius, r =
or
r = 22.81 × 10⁸ ft
The distance from the sun to the earth = 92.9 × 10 miles = 49.05 x 10¹⁰ ft
Now,
Lumen = Luminance × 4πr²
or
Lumen = 1600 × 10 cd/m² × 4πr² .....................(1)
also,
Illumination =
on substituting lumen from 1
Illumination =
or
Illumination =
or
Illumination = 346.01 × 10² Lux
A :-) F = mv^2 by t
Given - m = 10 kg
r = 10 m
v = 10 m/s
Solution -
F = mv^2 by t
F = 10 x 10^2 by 10
F = 10 x 100 by 10
( cut 10 and 10 because 10 x 1 = 10 )
F = 100 N
.:. The centripetal force is 100 N
Stay away from water. Try not to wash, shower, wash dishes, or have some other contact with water during a thunderstorm because lightning can travel through a building's plumbing.
Further Explanation:
Be aware
Check the climate conjecture before taking an interest in outside exercises. In the event that the estimate calls for tempests, defer your excursion or movement, or ensure sufficient safe house is promptly accessible.
Go inside
Keep in mind the expression, "When thunder thunders, go inside." Find a protected, encased asylum when you hear thunder. Safe havens incorporate homes, workplaces, strip malls, and hard-top vehicles with the windows moved up.
Hunch near the ground and isolated
On the off chance that you are gotten in an open zone, hunker down in a ball-like position (feet and knees together) with your head tucked and hands over your ears so you are down low with insignificant contact with the ground. Try not to rests. Lightning causes electric flows along the highest point of the ground that can be fatal more than 100 feet away. Hunching down is the best mix of being low and contacting the ground as meager as could be expected under the circumstances.
Discrete
On the off chance that you are in a gathering during a rainstorm, separate from one another. This will decrease the quantity of wounds if lightning strikes the
