Question # 3

Physics
1 answer:
Rzqust [24]3 years ago
7 0

Explanation:

The moment of A about B is given by the formula

M=Fd

where M is the moment, F is the force acting perpandicular to the axis of rotation about B by A, and d is the horizontal distance of A from B along the axis of rotation.

Now

F=230 (N)

(a) At X,

M=(230)(4/2)=460 (Nm)

(b) At 0.5m from X,

M=(230)(2-0.5)=345 (Nm)

(c) At Y,

M=-(230)(2)=-460 (Nm)

where negative sign indicates clockwise rotation of the child about Z.

(d) At Z,

M=(230)(0)=0 (Nm)

If the incoming photon had a frequency of 8.0 E14 Hz, would you have a photo-electron ejected?
cupoosta [38]

Yes.


In fact, from the graph we see that the threshold frequency (the minimum energy of the incoming energy needed to extract a photoelectron from the material) is 5.0 \cdot 10^{14} Hz (we see it because this is the frequency at which the maximum kinetic energy of the emitted electron is zero).


The incoming photon in this problem has a frequency of 8.0 E14 Hz, so above the threshold frequency, therefore it is enough to extract photoelectrons from the material.

A square, single-turn coil 0.132 m on a side is placed with its plane perpendicular to a constant magnetic field. An emf of 27.1
marta [7]

Answer:

0.35 T

Explanation:

Side, a = 0.132 m, e = 27.1 mV = 0.0271 V, dA / dt = 0.0785 m^2 / s

Use the Faraday's law of electromagnetic induction

e = rate of change of magnetic flux

Let b be the strength of magnetic field.

e = dФ / dt

e = d ( B A) / dt

e = B x dA / dt

0.0271 = B x 0.0785

B = 0.35 T
