Answer: The reason weight for average adult is 530N
Explanation: The clearly see this answer, let's convert this weight to kg using F=mg
530=m×9.8
g is a constant of 9.8m/s2
We divide both sides by 9.8 to get
54kg then this weight is reasonable for an average adult.
The term used for the total radiation that is reflected by a surface is albedo. It is the percent of solar energy that is being reflected from our Earth back into the space. It is a dimensionless value since it is a percentage and ranges from a value of zero (corresponds to a perfect black body where it absorbs all of the radiation) to one (corresponds to a white body where all radiation is being reflected). This term is very useful in astronomy, climatology and environmental management. The average albedo of Earth is found to range from 30 percent to 35 percent due to the clouds present in the atmosphere.
Answer:
a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously
D,
lmk if this is right :)
The hypotenuse is measured at 120 meters of string, and you need to solve for the leg of the triangle that is horizontal. The degree is 40, so use trigonometry to figure it out.
Cosin (40) is equal to around .766
Adjacent/Hypotenuse
x/120 = cos40
Answer: 91.92533.
If you use 3 significant figures it should be 91.9 meters.
