Answer:
The speed of the cyclist is 2.75 km/min.
Explanation:
Given
To determine
We need to find the speed of a cyclist.
In order to determine the speed of a cyclist, all we need to do is to divide the distance covered by a cyclist by the time taken to cover the distance.
Using the formula involving speed, time, and distance

where
substitute d = 88, and t = 32 in the formula


Cancel the common factor 8

km/min
Therefore, the speed of the cyclist is 2.75 km/min.
FORMULA:
- V = IR, where V = P.D; I = Current; R = Resistance.
ANSWER:
Total equivalent resistance for circuit:
R(eq) = R1 + R2 [It is in series]
Now, Current passing through whole circuit:
I = V/R
We know that, In series combination current passing through whole circuit is same.
So, V¹ = IR¹
V¹ = 1/50 × 330
And V² = IR²
V² = 1/50 × 470
When two vectors are in same direction then we add up to get their resultant and in this case resultant would be maximum
R = A + B
R = 4 + 2
R = 6
If vectors are in opposite direction then they provide minimum resultant and in this case we subtract them
R = A - B
R = 4 - 2
R = 2
