An electrically charged element is called an "ion". A neutral element is an atom.
Answer:
<h2>The current required winding is
</h2>
Explanation:
We can use the expression B=μ₀*n*I-------1 for the magnetic field that enters a coil and
n= N/L (number of turns per unit length)
Given data
The number of turns n= 1200 turns
length L= 0.42 m
magnetic field B= 1*10^-4 T
μ₀=
Applying the equation B=μ₀*n*I
I= B/μ₀*n
I= B*L/μ₀*n
To solve this problem we will apply the concepts related to power as a function of the change of energy with respect to time. But we will consider the energy in the body equivalent to kinetic energy. The change in said energy will be the difference between the two velocity data given by half of the mass. We will first convert the given units into an international system like this
Initial Velocity,
Final Velocity,
Now Power is defined as the change of Energy over the time,
But Energy is equal to Kinetic Energy,
Replacing,
Therefore the correct answer is A.
Answer:
4000 kg m/s
Explanation:
<u><em>p=mv</em></u>
- p = momentum in kg m/s
- m = mass in kg
- v = velocity in m/s
substitute values into the formula above to get:
p=1000x4
<u><em>p=4000 kg m/s</em></u>
