g A circular loop of wire with radius 3 m is flat on the xy plane in a magnetic field which is pointed in the z-direction and ha
Phantasy [73]

Answer:

emf=-0.035V

Explanation:

this problem can be solved with the Lenz's law:

emf=-\frac{\Delta \Phi_{B}}{\Delta t}

where PhiB is the magnetic flux. In this case we have

\Delta \Phi_{B}=B(A_1-A_2)

due to the magnetic field is constant. A is the area of the circular loop. Hence

\Delta \Phi_{B}=(5*10^{-3}T)(\pi(3m)^2-\pi(1.5m)^2)=0.106Tm^2

Finally

emf=-\frac{0.106Tm^2}{3s}=-0.035V

HOPE THIS HELPS!!

A short ramp and a long ramp each reach a height of 1 m. Which
Pavel [41]

Answer:

he longer ramp has more mechanical advantage for it requires less force to push up a mass while being over a longer period of time. Its called Mechanical Advantage because say you had to lift a car up 1-meter. you cannot simply pick it up, but over a long enough slope you would be able to because you can apply a small force over a longer distance

A combined circuit has two resistors in series (27.5 ohms and 33.0 ohms) and another in parallel (22.0 ohms). If the power sourc
Dafna1 [17]
R 1,2 = 27.5 + 33.0 = 60.5 Ohms
1/ R 1,2,3 = 1/ 60.5 + 1 / 22 = 82.5 / 1331
R 1, 2, 3 = 1331 / 82.5 = 16.13 Ohms
I = U / R
I = 9 V / 16.13 Ohms = 0.557 A ≈ 0.56 A

Would you hear an echo if you shouted in your bedroom? Explain your answer.
Sindrei [870]

Answer:

if your bedroom is empty yes but if not most likely no

Explanation:

Why Cannot we hear an echo in a small room?

They can't hear an echo in small room because in it the sound can't be reflected back. For an echo of a sound to be heard,the minimum distance between the source of sound and the walls of the room should be 17.2 m.Obviously,in a small room echoes cannot be heard.
