A circular loop of flexible iron wire has an initial circumference of 165.0cm, but its circumference is decreasing at a constant

djverab [1.8K]

Answer:

0.005 V

Explanation:

We are given that

Initial circumference of circular loop=C=165 cm

Rate of circumference, $\frac{dC}{dt}=12 cm/s$

Magnetic field,B=0.5 T

We have to find the induced emf at time t=9 s

We know that induced amf,E= $\frac{Bd(A)}{dt}$

Area of circular coil,A= $\pi r^2$

$E=B\frac{d(\pi r^2)}{dt}=B(2\pi r)\frac{dr}{dt}$

Circumference of circular coil,C= $2\pi r$

$165=2\pi r$

$r=\frac{165}{2\pi}$

$\frac{dr}{dt}=\frac{1}{2\pi}\frac{dC}{dt}=\frac{1}{2\pi}\times (12)=\frac{6}{\pi} cm/s=\frac{6\times 10^{-2}}{\pi} m/s$

Radius of coil at time t=9 s

$r=\frac{165}{2\pi}-(\frac{6}{\pi}\times 9)=9.08 cm=9.08\times 10^{-2} m$

$1 m=100 cm$

E= $-0.5(2\pi\times 9.08\times 10^{-2})\times \frac{6\times 10^{-2}}{\pi}=-0.005 V$

Magnitude of induced emf=0.005 V

You have decided to select a new car by using the scientific method. how would you proceed? Please answer!!!

hammer [34]

We look at the criteria to select a car.

If we are not too rich, we have to bother about fuel efficiency. The mileage in terms
   of km per liter or miles per gallon etc.

engine power - whether it is good enough over a slope (steep) that I may encounter
   frequently with my family members.

internal space / total external size : or internal space / total price:
   We find these numbers. after all , we make use of the internal space on seats.
   we have to know its proportion in the total volume of the car.

the axle turning capability, wheel turning ability :
   see the minimum radius and span required to turn a car in a U turn.

we have to bother about its pollution, emission level.

height / width ratio, which is important for the balance of the car.

==================================
If we are looking at the economic point of view
   monthly benefit/savings of using the car,converted into currency - Loan EMI

When you jump over something is it a balanced force?

Marta_Voda [28]

Answer:

no..

Explanation:

in balanced force it will or in this case u would stay still or u would move at the same speed.. but when u jumps the speed changes..so this is an unbalanced force

hope my ans helps
