The battery of a flashlight develops 3 V, and the current through the bulb is 200 mA.What power is absorbed by the bulb?
Verizon [17]

Answer : The power absorbed by the bulb is, 0.600 W

Explanation :

As we know that,

Power = Voltage × Current

Given:

Voltage = 3 V

Current = 200 mA = 0.200 A

Conversion used : (1 mA = 0.001 A)

Now put all the given values in the above formula, we get:

Power = Voltage × Current

Power = 3V × 0.200 A

Power = 0.600 W

Thus, the power absorbed by the bulb is, 0.600 W

A large ant is standing on the middle of a circus tightrope that is stretched with tension T_s. The rope has mass per unit lengt
k0ka [10]

Answer:

A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}

Explanation:

As we know that the speed of the wave in string is given as

v = \sqrt{\frac{T_s}{\mu}}

now we will have

frequency of the wave is given as

f = \frac{v}{\lambda}

f = \frac{1}{\lambda}\sqrt{\frac{T_s}{\mu}}

now if the ant will feel weightlessness then we will have

mg = m\omega^2 A

so we will have

A = \frac{g}{\omega^2}

A = \frac{g}{4\pi^2 f^2}

A = \frac{g \lambda^2 \mu}{4\pi^2 T_s}

Please help meeeeeeeeeeeeeeeee
Julli [10]

I can't see the answers clearly, but I can see the question. So, I'll just give you a clue/hint.

A stars brightness actually depends on how far it is from your location. If it's far away, it will be dimmer than its counterpart that is closer. To summarize it, if two stars have the same brightness level and one is farther away than the other, the one farther away will appear dimmer than its closer counterpart.
