Answer:
v = 16.98 km/s
Explanation:
Given that,
Distance, d = 4500 km
Time, t = 265 s
We need to find its average speed. The total distance covered divided by total time taken is called average speed of an object. So,
So, the average speed is 16.98 km/s.
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]
