Incomplete question as we have not told which quantity to find.So the complete question is here
A solenoid used to produce magnetic fields for research purposes is 2.2 mm long, with an inner radius of 25 cmcm and 1300 turns of wire. When running, the solenoid produced a field of 1.5 TT in the center.Given this, how large a current does it carry?
Answer:
Explanation:
Magnetic field B=1.5 T
Length L=2.2mm =0.0022m
Number of turns N=1300 turns
To find
Current I
Solution
From the magnetic at the center of loop we know that:
Substitute the given values
The answer is statement 4. This is the most unique property of water since most materials becomes more dense when it undergoes transition from liquid to solid. However, this is not the case of water. When water freezes it becomes less dense because the hydrogen bonds causes the molecule to push each other farther apart.
Answer:
d) 0.011%
Explanation:
The probability for tunneling the barrier is given by the following formula:
( 1 )
me: mass of the electron
Uo: energy of the barrier
E: energy of the electron
d: thickness of the barrier
By replacing the values of the parameters in (1), you obtain:
hence, the probability is 0.011% (answer d)
Answer: 1. A Unbalanced force and net force
Explanation:
The combination of all forces acting on a object is called a Net Force, and a Unbalanced force can cause an object to stop, start moving or change direction.
