.An 850 turn solenoid with a diameter of 7.0cm is 21 cm long with 42A of current.A long straight wire cuts through the center of

the solenoid, along a diameter.This wire carries a 22A current upward.What is the force on this wire assuming the solenoid's field points due east

Answer:

The answer is that there is no magnetic force on the wire. The force on a wire is the cross product of the current thru it and the magnetic field it is in. In your case, both are parallel and the cross product is therefore zero.

Explanation:

F = (n x i)2 x magnetic constant x a / (2 x g2)

Where,

F = Force, i = Current, g = Length of the gap between the solenoid and a piece of metal, a = Area n = Number of turns, Magnetic constant = 4 x PI x 10-7.

erik [133]

Answer:

Initial pressure = 6 atm. Work = 0.144 J

Explanation:

You need to know the equation P1*V1=P2*V2, where P1 is the initial pressure, V1 is the initial volume, and P2 and V2 are the final pressure and volume respectively. So you can rearrange the terms and find that (1.2*0.05)/(0.01) = initial pressure = 6 atm. The work done by the system can be obtained calculating the are under the curve, so it is 0.144J

How much force (in Newtons) acts on a 1700 kg car going around a
Daniel [21]

Answer:

b) 4781 N

Explanation:

Because there is a redius do this question is talking about the acceleration force which= mv^2/r

so a=15^2/80=2.8125 m^2/s

so the force will be = m.a

F =1700×2.8125=4781.25 N

How can you decrease the momentum of an object?
mamaluj [8]
You will have to "put force against the object to slow it down." Momentum is the force that is keeping a object moving in a certain direction so if you would want to slow down the object you will have to put another force against the object to slow it down or stop it. For example: a person kicks a ball, the ball moving is the momentum. So, if you would want to stop the ball you would have t put something in its path to slow it down which is the decreasing of it's momentum. Therefore you would put a bump in the wall and when the ball hits the bump it slows down.

Hope this helps!

An object rotates about a fixed axis, and the angular position of a reference line on the object is given by θ = 0.220e3t, where
OLga [1]

Answer:a_{t}=3.96

a_{c}=0.8712

Explanation:

Given

\theta =0.220e^{3t}

r=2cm

Now angular velocity is given by \omega =\frac{\mathrm{d}\theta}{\mathrm{d}t}

\omega =0.66e^{3t}

Now linear velocity(v) is given =\omega r

v=1.32e^{3t}

Now tangential component of acceleration is given by

a_{t}=\frac{\mathrm{d}\vec{v}}{\mathrm{d}t}=3.96e^{3t}

at t=0

a_{t}=3.96cm/s^2

radial component of acceleration is given by

a_{c}=\omega ^{2}r

a_{c}=0.4356e^{6t}\times 2

a_{c}=0.8712e^{6t} cm/s^{2}

at t=0

a_c=0.8712 cm/s^{2}
