Answer:
32km per hour
Explanation:
Explanation:
In first case v = a t
==> a t = 40 km p h
Now distance covered S1 + S2 + S3
S1 = 1/2 a t^2 and S3 = 1/2 a t^2
But S2 = 3t * 40 = 120 t km
Hence total distance = at^2 + 120 t
Time taken (total) = t + 3t + t = 5 t
Hence average speed = at^2 + 120 t / 5 t
Cancelling t we have at + 120 / 5 = 40 + 120 / 5 = 160/5 = 32 km per hour
The overall electrical resistance that a circuit experiences as a result of all of its resistors acting in concert against its voltage source are known as the equivalent resistance of the circuit.
<h3>What is equivalent resistance?</h3>
The total resistance, or equivalent resistance, is equal to the mathematical sum of the two resistances if there are two unequal resistors or impedances in a series.
Where the whole resistance is connected in parallel or series is known as the equivalent resistance. Electrical resistance indicates the amount of energy needed to transfer the charges, or current, across the circuit.
The total or equivalent resistance, RT, is equal to half the value of one resistor if the two parallel resistances or impedances are equal and of the same value.

Answer:
7.2375m/s^2
Explanation:
initial velocity=-25 km/h=-6.94m/s
final velocity=35 km/h=9.72m.s
distance=3.2m
v^2=u^2+2as
9.72^2=-6.94^2+2a*3.2
94.48=48.16+6.4a
(94.48-48.16)/6.4=a
7.2375m/s^2
Answer:
Explanation:
V = I R
V = 0.0418 * 30
V = 1.254
