Answer:

The induced current in the resistor is I = BLv/R

Explanation:

The induced emf ε in the long bar of length, L in a magnetic field of strength, B moving with a velocity, v is given by

ε = BLv.

Now, the current I in the resistor is given by

I = ε/R where ε = induced emf in circuit and R = resistance of resistor.

So, the current I = ε/R.

substituting the value of ε the induced emf, we have

I = ε/R

I = BLv/R

So, the induced current through the resistor is given by I = BLv/R

Describe how air quality has changed since the Industrial Revolution.
Alisiya [41]

Answer:

MRCORRECT has answered the question

Explanation:

The Industrial Revolution impacted the environment. The world saw a major increase in population, which, along with an increase in living standards, led to the depletion of natural resources. The use of chemicals and fuel in factories resulted in increased air and waterpollution and an increased use of fossil fuels.

zloy xaker [14]

Answer:

* thermal energy

potential energy,

potential energy

Explanation:

The ship has various types of energy,

* thermal energy. This energy is associated with the temperature of the coal, the hotter the greater its internal energy,

* potential energy                                                                              this energy is stored in the constituent atoms within carbon

* potential energy. It is due to the configuration of the system, in this case the sun heats the coal

A current of 1.4 A flows in a conductor for 7.0 s. How much charge passes a given point in the conductor during this time?
bija089 [108]

Answer:

The charge passes a given point in the conductor during this time is 9.8 C.

Explanation:

Given that,

Current = 1.4 A

Time = 7.0 sec

We need to calculate the charge during this time

Charge :

Charge is the product of current and time.

In mathematically form,

Q = i\times t

Where, i = cirrent

t = time

Put the value into the formula

Q =1.4\times7.0

Q=9.8\ C

Hence, The charge passes a given point in the conductor during this time is 9.8 C.
