A large magnetic flux change through a coil must induce a greater emf in the coil than a small flux change.

Kazeer [188]

Answer:

flux change is more the induced emf is more.

Explanation:

According to the Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is directly proportional to the induced emf in the coil.

e = - d∅ / dt

So, if the flux change is more the induced emf is more.

A force Fx=cx-3.00x2 acts on a virus as the virus moves along an x axis, with F measured in Newtons, x in meters, and c a consta

andrey2020 [161]

Answer:

Explanation:

We are given that

$F_x=cx-3x^2$

K.E at x=0 m=20 J

K.E at x=3 m=11 J

We have to find the value of c.

By work energy theorem

Work done=Change in kinetic energy

W= $\int_{0}^{3} Fdx=\int_{0}^{3}(cx-3x^2)dx$

$W=[\frac{cx^2}{2}-x^3]^{3}_{0}$

$W=\frac{9c}{2}-27$

$\Delta K=11-20=-9 J$

$-9=\frac{9c}{2}-27$

$-9+27=\frac{9c}{2}$

$18=\frac{9c}{2}$

$c=\frac{2}{9}\times 18=4$

Select the correct answer.

swat32

Answer:

Work and time

Explanation:

(1) Power of a machine is given by :

$P=\dfrac{work\ done}{time\ taken}$

The work done of a machine is directly proportional to the work done and inversely proportional to the time taken by it.

So, the power of a machine depend on the work done and time taken. The correct option is (c) "work and time".

(2) This part is same as part 1.

i.e. power = work done/ time

or P = W / t

Hence, the correct option is (c) " work and time ".
