Answer:
Please refer to the explanation below.
Explanation:
Let
Radius of parallel plate capacitor = r
Distance between parallel plates of the capacitor = R
Area of parallel plate capacitor = Ar
Area of Distance between parallel plates of the capacitor = AR
Constant Current = I₀
Permeability of free space = μ₀
Induced magnetic field = B
From the Ampere's Maxwell law the magnetic field is given by
∫B.ds = μ₀I₀
∫B.ds = μ₀I₀Ar/AR
When the radius of the plates is much less than the distance between the parallel plates (r < R)
∫B.ds = μ₀I₀πr²/πR²
∫B.ds = μ₀I₀r²/R²
s = 2πr
B.2πr = μ₀I₀r²/R²
B = μ₀I₀r²/2πrR²
B = μ₀I₀r/2πR²
When the radius of the plates is much larger than the distance between the parallel plates (r > R)
∫B.ds = μ₀I₀
B.2πr = μ₀I₀
B = μ₀I₀/2πr
Bonus:
The magnetic field will be maximum when the radius of the parallel plate capacitor is equal to he distance between the parallel plate capacitor that is r = R
B = μ₀I₀/2πR

Answer:
Explanation:
Displacement is the change in the position of an object.
Abigail runs a complete lap around the track, which is 400 meters. Even though she ran 400 meters, she has <u>no displacement.</u> If she starts and ends at the same spot, there is no change in position.
Gabi runs a 50 meter dash in a straight line. Gabi has <u>50 meters of displacement</u>. She runs in a straight line and is 50 meters away from where she began.
While Abigail ran the farther distance, <u>Gabi had the greater displacement.</u>
Answer:
The correct option is D
Explanation:
When an object at rest is acted upon by an external force, the motion gained (of the body) will proceed in the direction of the force. <u>This is caused by the workdone by the bat on the ball</u>. The motion gained mentioned earlier is the kinetic energy.
Kinetic energy can be described as the energy in a moving object.
Answer:
the angular momentum of the paticle is 8.4i - 10.2j.
Explanation:
the angular momentum is given by:
L = m×v×r
= (1.40)×(4.00i - 3.30j)×(1.50i + 2.20j)
= (1.40)×[(4.00×1.50)i - (3.30×2.20)j]
= (1.40)×(6i - 7.26j)
= 8.4i - 10.2j
Therefore, the angular momentum of the paticle is 8.4i - 10.2j.
