Why a bulb contains coiled wire?​

Physics
1 answer:
LiRa [457]2 years ago
4 0

Answer:

The filament is coiled to give it greater length. If the filament was just a piece of straight wire it would only give out a small amount of light. By curling the wire into a coil, a very long length of wire can be stored in a small space. When electricity flows through the coil it can give out much more light.

An object is moving with a constant velocity of 278 m/s. How long will it take it to travel 7500 m, using the formula Delta X=Vt
rusak2 [61]
If the velocity is constant then the acceleration of the object is zero.
a=0 (m/s^2)
Thus when we apply the equation
\Delta X=vt+(at^2/2)
It remains
\Delta X =vt
or equivalent
t=(\Delta X/v) =7500/278 =26.98 (seconds)

tatyana61 [14]

Hello!

\large\boxed{KE = 50J}

Use the formula for kinetic energy:

KE = \frac{1}{2}mv^{2}

Plug in the given mass and velocity:

KE = \frac{1}{2} (4)5^{2}

Simplify:

KE = \frac{1}{2} (100)\\\\KE = 50 J
