Answer:

False

Explanation:

Water hardness in most groundwater is due to a natural occurrence caused by the weathering of limestone, sedimentary rock and calcium bearing minerals. Hardness can also occur locally in groundwater from chemical and mining industry effluent or excessive application of lime to the soil in agricultural areas.

Limestone is not a metallic element or metallic alloy, although it does contain the metallic element calcium, it is not formed by the same processes as metals are.

A long bar slides on two contact points and is in motion with velocity ν. A steady, uniform, magnetic field B is present. The in

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
