Answer:
10,200 Cal. per day
Explanation:
The mouse consumes 3.0 Cal each day, and has a mass of 20 grams. We can use this data to obtain a ratio of energy consumption per mass
.
For the human, we need to convert the 68 kilograms to grams. We can do this with a conversion factor. We know that:
,
Now, we can divide by 1 kg on each side
,
.
Using this conversion factor, we can obtain the mass of the human in grams, instead of kilograms. First, lets take:
We can multiply this mass for the conversion factor, we are allowed to do this, cause the conversion factor equals 1, and its adimensional
Now that we know the mass of the human on grams, we can multiply for our ratio of energy consumption
So, we would need 10,200 Cal per day.
Answer:
F=5.7×10⁻⁶
Explanation:
Not knowing a formula outright, I decided to follow the units of some relationships I did know. Radiation pressure is defined as force per area and also intensity divided by velocity (the speed of light here of course). Breaking intensity down into power per area and isolating force gave me the relationship F=(Power/Velocity),where power is given and the velocity is a constant.
My work is in the attachment, where I double checked the units too, comment with any questions.
