The resistance of 100 W bulb is less than resistance of 40 W bulb. Explain the reason.

Physics
1 answer:
vazorg [7]4 years ago

Ok so we know that electric power is:

P=UI=I^2R

If we express resistance.

R=\dfrac{P}{I^2}

Now if you have 100W of power you will probably get a bigger resistance than with 40W of power.

However here it says that the resistance of 40W bulb is bigger than 100W bulb. Which means the statement is incorrect.

Hope this helps.

Passengers on an airplane move from rest to 86 meters per second before the airplane takes off. If the airplane takes 100 second
VikaD [51]

Utilize the formula:  V _{f} = V _{i} + a\Delta t

V _{f} = Final Velocity (86 m/s)

V _{f} = Initial Velocity (0 m/s)

a = acceleration (m/s²)

\Deltat = Time (100 seconds)

As a result,

86 m/s = 0 + (a)(100 seconds)

Using algebra, divide 86 m/s by 100 seconds:

86 m/s = 100a

a = 0.86 m/s²

Rounded to one decimal place: 0.9 m/s²

Let me know if you have any questions!
