Answer:
B = 1.67 μ T
Explanation:
given,
current, I = 1 x 10⁴ A
r = 120 m
treating lightning bolt as long straight conductor


resulting magnitude would be equal to
B = 16.67 x 10⁻⁶ T
B = 1.67 μ T
The resulting magnetic field is equal to B = 1.67 μ T
Mass is a property of the object. It doesn't depend on anything else,
and it doesn't change when the object goes to different places.
Its mass is always the same.
If it's 20,000 kilograms on Earth, then it's 20,000 kilograms on the
Moon, on Mars, in school, in bed, in love, in trouble, in water,
on Pluto, on Halley's comet, or in free fall in outer space.
That's why choice-B is the correct choice.
Now, if the question was talking about WEIGHT, then we would have
a lot to talk about, because WEIGHT depends on where you are, and
what else is around you. But mass doesn't.
Answer: A
Hope this help you!!
The correct answer for this question is this one: "Potential Energy."
Potential energy is the energy that is transferred by the movement of electrons through a conductor the electrons create circuit. It is energy at moving. Hope this helps answer your question and have a nice day ahead.
The period of a simple pendulum is given by

where
L is the pendulum length
g is the acceleration of gravity
If we move the same pendulum from Earth to the Moon, its length L remains the same, while the acceleration of gravity g changes. So we can write the period of the pendulum on Earth as:

where

is the acceleration of gravity on Earth, while the period of the pendulum on the Moon is

where

is the acceleration of gravity on the Moon.
If we do the ratio of the two periods, we get

but the gravity acceleration on the Moon is 1/6 of the gravity acceleration on Earth, so we can write

and we can rewrite the previous ratio as

so the period of the pendulum on the Moon is
