Power is the ratio between energy and time:
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
Yes water is liquid.
Explanation: At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second.
When you sort the ranges of EM waves from lowest to highest frequency, the visible light range is just higher than infrared (think "below red") and just lower than ultraviolet (think "above violet").
Choice E.
Answer:
The water content of this borrow material is 0.194
Explanation:
Given that,
Weight of material = 123 pcf
Weight of dry sample = 103 pcf
We need to calculate the water content of this borrow material
Using formula of water content
Where, w = weight of water
= dry unit weight
= unit weight
Put the value into the formula
Hence, The water content of this borrow material is 0.194
