Answer:
The charged particle follows a spiral path in a magnetic field.
Explanation:
A charge immersed in a region with an electric field experiences a force that acts along the same direction of the electric field. In particular:
- The force has the same direction as the electric field if the charge is positive
- The force has the opposite direction as the electric field if the charge is negative
Therefore, a charge moving in an electric field is accelerated along the direction of the electric field.
On the other hand, a charge in motion in a region with a magnetic field experiences a force that acts perpendicular to the direction of the field. This means that a charge in motion in a magnetic field will acquire a circular motion in the plane perpendicular to the direction of the magnetic field.
As a result, if the particle has also a original motion outside this plane, its final motion will consist of:
- A uniform motion along that direction, +
- A circular motion along the plane perpendicular to the field
So, the resultant motion of the particle will be a spiral path. So the correct answer is
The charged particle follows a spiral path in a magnetic field.
1) Because you have a lower chance of getting electrocuted, 2) 1.DON'T plug a bunch of stuff into one outlet or extension cord, 2.Make sure all electric cords are tucked away neatly, 3.DON'T ever climb the fence around an electrical substation, 4.DON'T yank an electrical cord from the wall, 5.Keep electrical stuff far away from water, 6.Ask a grown-up for help. 3) <span>Always determine if there is power to a circuit or wire using a voltmeter. Never touch any part of a circuit if you did not verify yourself that the the power is off(disconnected). { Trust but verify :President R. Reagan} Having turned off or disconnected the power assure that it cannot be accidentally turned on again by another person. Your Welcome.</span>
Answer:
The angular velocity of the wheel in terms of d, F, and I is, ω = d/t (F/I α) s⁻¹
Explanation:
Given,
The angular velocity ω
The displacement d
The magnitude of the applied force, F
The moment of inertia of the wheel I = mr²
The angular velocity can be written as
ω = v /r
where,
v - linear velocity
r - radius of the wheel
ω = d/t (1/r) (∵ v = d /t)
The force can be written as,
F = m a
= m α r (∵ a = α r)
Multiplying both sides by r
F r = m r² α
F r = I α (∵ I = mr²)
r = I α / F
Substituting in the above equation for ω
ω = d/t (F/I α) s⁻¹
Hence, the angular velocity of the wheel in terms of d, F, and I is, ω = d/t (F/I α) s⁻¹
Answer:350.92 KJ/kg
Explanation:
Given the process is reversible adiabatic i.e it is isentropic
From steam table
For isentropic process 
at
Therefore Work output of the turbine per unit mass of steam is =
=3317.03-2966.11
=350.92 KJ/kg
Speed = distance / time
speed = 100 / 11
speed = 9.09m/s
to get rid of meters and get miles you want to multiply by 1 mile then divide by 1609 meters. to get hours, you times the amount of seconds in an hour (3600) and divide by 1 hour
9.09m/s × 1mile / 1609m × 3600s / 1 hour = 20.3 miles / hour
