Explanation

Never connect ohm meter on live circuits to avoid electric shock or damage.

Explanation

The correct option will be 2 milliamperes ( according to the NTS answer key).

*****

In reality, 2 mA typically causes a mild tingling sensation or a slight shock, but it is not enough to cause severe injury or put someone into a coma.

For a current to potentially cause a coma, it usually needs to be in the range of 50 to 100 mA.

Explanation

Typically, metals, metal alloys, electrolytes and even some nonmetals, like graphite and liquids, including water, are good electrical conductors.

Pure elemental silver is one of the best electrical conductors.

Explanation

In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.

For example, 3x² − 2xy + c is an algebraic expression.

Explanation

The acceleration of body due to the constant velocity is zero

Explanation

 5-2r > 1

 -2r > 1 - 5

-2r > -4

r=-4/-2

r=2

Explanation

If a set contains n elements, then the number of subsets of this set is equal to 2ⁿ − 1.

The only subset which is not proper is the set itself.

So, to get the number of proper subsets, you just need to subtract one from the total number of subsets.

Explanation

The coefficient of -2x is -2

Explanation

The value of g at a particular point outside the earth is 10 m/s2.

Explanation

Volt is the unit of measurement for the potential difference that cause a current to flow through a conductor.
