From the definition of average velocity,
,
and the fact that constant acceleration means
we can solve for the time :
Answer:
The ratio is 0.667.
Explanation:
We are given two incandescent lights which have ratings of 75 W and 50 W .
Both bulbs operate at the same voltage.
The equation of power consumed is given by P =
Therefore the resistance for the 75 W bulb =
Therefore the resistance for the 50 W bulb =
Therefore the ratio of the resistance for the 75 W bulb to the resistance of the 50 W bulb is equal to
= = = 0.667.
The ratio is 0.667.
Answer:
a vacuum formed above the column of mercury in a mercury barometer.
No.
In the northern hemisphere, summer is consider to be around June/July/August.
In the Southern Hemisphere, it is the opposite: summer is in the months of December/January/February.
In some areas such as near the equator, the seasons themselves differ. For example, where I live, we have three seasons: wet season, dry season, and build up.
Hope this helps.
Answer:
Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.
