As we know that power is defined as rate of work done

so we will have

$P = \frac{Work}{time}$

so in order to increase the power as per above formula we know that either we need to increase the work or we need to decrease the time to complete that work

So here the correct answer will be

increase the work being done or decrease the time in which the work is completed.

Explain why Earth is not spherical in shape, but bulges at<br> theEquator?

Strike441 [17]

Explanation:

Every rotating body experiences centrifugal force. Due to this force the body tends to bulge out around it mid point and gets flattened at the poles. Same is applicable to Earth as well. Since the Earth is rotating at a very high speed, its equator gets bulged out due to centrifugal force. Because of this bulged equator, Earth's pole to pole diameter and equatorial diameter has difference of around 42.76 km. It is flatter on the poles. This also proves that Earth is not a perfect sphere.

A student is concerned about background radiation that she is exposed to. She claims that nuclear power plants have caused backg

denis-greek [22]

Based on the given statement or reasoning above made by a student, what makes her reasoning incorrect is the part where she mentioned that "if they had not been built, she would not be exposed to radioactivity." This is definitely false. What makes this incorrect is that background radiation is a kind of radiation that is emitted by the sun, stars, and other bodies outside the universe and therefore, no one can escape from this. Hope this helps.

If the electron has a speed equal to 9.10 x 10^6 m/s, what is its wavelength?

Fudgin [204]

Answer:

$\lambda=8.006\times 10^{-11}\ m$

Explanation:

Given that,

The speed of an electron, $v=9.1\times 10^6\ m/s$

We need to find the wavelength of this electron. It can be calculated using De -broglie wavelength concept as :

$\lambda=\dfrac{h}{mv}$

h is the Planck's constant

$\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-31}\times 9.1\times 10^6}$

$\lambda=8.006\times 10^{-11}\ m$

So, the wavelength of the electron is $8.006\times 10^{-11}\ m$ . Hence, this is the required solution.

Explain maximum and minimum thermometer working(answer only for points will be reported)

belka [17]

Explanation:

Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. One side registers the maximum temperature and the other side records the minimum temperature.
The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol.
When the temperature rises, the alcohol expands and pushes the mercury up the maximum column. This also pushes the mercury down in the minimum column.
Similarly, when the temperature falls, the alcohol contracts and pulls the mercury up in the minimum column resulting in a fall of mercury in the maximum column.
The steel indexes are located on the surface of mercury. They move along with the flow of mercury up and down.
When the temperature reaches its maximum and minimum limits, the metal indexes remain at that place. This helps in recording the maximum and minimum temperatures of the day.
