Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B =
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
Answer:
The free fall acceleration on the surface of this planet is 4.35 m/s²
Explanation:
Given that,
Mass of planet
Radius of planet
We need to calculate the free fall acceleration on the surface of this planet
Using formula of gravity
Where, = mass of planet
= radius of plane
Put the value into the formula
Hence, The free fall acceleration on the surface of this planet is 4.35 m/s²
4. Dark Energy.
This is the mysterious force causing the expansion of space. No one has ever seen this force.
I would have to say B failed because I think I read something about it being only 2law not 3
