Answer:

<h3>1.8 seconds</h3>

Explanation:

  • Initial velocity (u) = 0 m/s

[Since, it is at rest. ]

  • Acceleration (a) = 0.0075 m/s²
  • Final velocity (v) = 0.0135 m/s²

We are asked to calculate time taken to reach a speed of 0.0135m/s.

By using the first equation of motion,

<h3>→ v = u + at</h3>

  • v denotes final velocity
  • u denotes initial velocity
  • a denotes acceleration
  • t denotes time taken

Substituting values,

→ 0.0135 = 0 + 0.0075t

→ 0.0135 = 0.0075t

→ 0.0135 ÷ 0.0075 = t

→ 1350000 ÷ 750000 = t

→ 135 ÷ 75 = t

→ 1.8 = t

<h3>→ Time taken = 1.8 seconds</h3>

<u>Therefore</u><u>,</u><u> </u><u>it</u><u> </u><u>takes</u><u> </u><u>1</u><u>.</u><u>8</u><u> </u><u>seconds</u><u> </u><u>to reach a speed of 0.0135m/s</u><u>.</u>

When comparing two circuits, you note that circuit one has twice the resistance and double the voltage of circuit two. This mean
pochemuha

This means that there is same current flow in both the circuit, or the circuit one has twice the power of circuit two.

According to ohm's law, the resistance is given as

I=V/R

Since the circuit one has twice the voltage, and resistance
