At the end of the previous experiment, aclumsy scientist drops the coil, while still in the magnetic field, and still oriented w

ith its plane perpendicular to the magnetic field, denting it and changing its shape to a semi-circle. The new shape has the same perimeter, but a different area, and it takes 0.036s to deform. What isthe average induced EMF during this mishap

Answer:

hello your question has some missing parts below are the missing parts

A Circular, 10-turn coil has a radius of 10.7 cm and is oriented with its plane perpendicular to a 0.2-T magnetic field.

answer : 1 volt

Explanation:

<u>Determine the Average induced EMF during this mishap</u>

A' = A/2  ( for a semi circle )

where A = \frac{\pi r^2}{2}

To determine the Average induced EMF apply the relation below

| E | =  η * \frac{\beta A}{T}   ----- ( 1 )

Replace A in equation 1 with  A = \frac{\pi r^2}{2}

hence equation becomes : | E | =  η * βπr^2 / 2T'

where : T' = 0.0365 ,  β = 0.2 , η = 10 , r = 0.107

∴| E |  = 0.999 ≈ 1volts

Anni [7]

Answer:

\frac{dQ}{dt} = 966 W

Explanation:

As we know that the rate of heat transfer due to temperature difference is given by the formula

\frac{dQ}{dt} = \frac{KA(\Delta T)}{L}

here we know that

K = 0.69 W/m-K

A = 4 m x 7 m

thickness = 30 cm

temperature difference is given as

\Delta T = 20 - 5 = 15 ^oC

now we have

\frac{dQ}{dt} = \frac{(0.69W/m-K)(28 m^2)(15)}{0.30}

\frac{dQ}{dt} = 966 W

For the meter stick shown in figure 10-4, the force F1 10.0 N acts at 10.0 cm. What is the magnitude of torque due to F1 about a
Phantasy [73]

Torque is equal position vector times (r) times force vector (F).  Since F= 10 N and r = 0.1 m, so the torque is equal to (10 N) x ( 0.1 m) = 1Nm. The direction of the torque would be into the screen, clockwise rotation.

a farmer lifts a bale of hay that is 12m off the ground . If he uses a force of 350 n, how much work does the farmer do?
hjlf

Answer:

4200 Joules

Explanation:

Work done =force x distance

From the question , we’re given f =350N ,

d = 12m

Using the above formula, we have

Workdone = 350 x 12

= 4200 Joules
