Explanation:
The density of an object can be calculated using the formula as follows :
Here,
m is mass of the object and V is its volume
The mass of an object can b measured in grams and its volume in cubic cm. So, the density of object is measured in g/cm³. Hence, out of given options the possible value of density of an object is 6 g/cm³.
As per the question, the resistor system contains two resistors.
The two resistors are denoted as
We are asked to calculate the effective resistance in terms of
The two resistors can be connected in two ways.
CASE-1: Let the resistors are connected in series.
When the resistors are connected in series, the effective resistance is the algebraic sum of the individual resistors.
Hence, the effective resistance [ans]
CASE-2: Let the resistors are connected in parallel.
The effective resistance is calculated as follows-
⇒ [ans]
