In a region of space, a magnetic field points in the +x-direction (toward the right). Its magnitude varies with position accordi

ng to the formula Bx=B0+bx, where B0 and b are positive constants, for x≥0. A flat coil of area A moves with uniform speed v from right to left with the plane of its area always perpendicular to this field. Part A What is the emf induced in this coil while it is to the right of the origin?

Answer:

E=Abv

Explanation:

We are given that

B_x=B_0+bx

For x\geq 0

Area of coil=A

Speed=v

We have to find the emf induced in the coil while it is to the right of the origin.

We know that induced emf

E=-\frac{d\phi}{dt}

\phi=BA

E=-\frac{d(A(B_0+bx)}{dt}

E=-A(b)\frac{dx}{dt}

We know that

v=-\frac{dx}{dt}

Substitute the value

E=Abv

Which of the following quantities is inversely proportional to the gravitational pull between two objects?
Contact [7]

Answer:

C

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces

I hope this helps a little bit

A power station with an efficiency e generates W watts of electric power and dissipates D J of heat energy each second to the co
Andrews [41]

Answer: 13.94 tons/s

Explanation:

On adding heat energy to a substance, the temperature would be changed by a particular amount. This relationship between heat energy and temperature is often different for each material. The specific heat, is a value that describes how they relate.

Heat energy = mass flow rate * specific heat * Δ T

Q = MC (ΔΦ)

Heat energy, Q= 3.5*10^8J

Mass flow rate, M= ?

Specific heat, C= 4184j/KgC

Change in temperature, ΔΦ= 6°C

M = Q/CΔΦ

M = (3.5*10^8)/4184*6

M = 13942kg/s

M = 13.94 tons/s
