Answer:
The magnetic field at the center of the solenoid is 2.1 × 10⁻³ T
Explanation:
The magnetic field B at the center of the solenoid is given by
B = μ₀ni where μ₀ = permeability of free space = 4π × 10⁻⁷H/m, n = number of turns per unit length of the solenoid = 1100 turns per meter and i = current in the solenoid = 1.5 A.
So B = μ₀ni
= 4π × 10⁻⁷H/m × 1100 × 1.5 A
= 4π × 10⁻⁷H/m × 1650 A-turns/m
= 20734.5 × 10⁻⁷T
= 2.07345 × 10⁻³ T
≅ 2.1 × 10⁻³ T
So the magnetic field at the center of the solenoid is 2.1 × 10⁻³ T
Answer:
No
Explanation:
I don't think the universe has a starting and ending point because the universe is vast and has not been fully discovered. I think that the universe is endless because all of the stars, planets, and galaxy's have yet to be found and the end or start of the universe is also yet to be discovered so I think that the universe could go on forever.
Answer:
<h2>760 m/s</h2>
Explanation:
The jet's speed or final velocity can be found by using the formula
<h3>v = u + at</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
v = 600 + 20(8)
= 600 + 160
We have the final answer as
<h3>760 m/s</h3>
Hope this helps you
If the earth did not rotate, one half of the earth would be dark and the other side of the Earth would be light. The bright side would be too hot and the other side would be too cold. Also if the Earth did not rotate, then the two poles and the equator would be easily effected.
