Answer:
1.20372
Explanation: start with 39 times 2 for how much grams each day and then multiply that by 7 then the convert grams into pounds
Answer:
1.15*10^-7 N/m²
Explanation:
Radiation pressure is the pressure exerted on any surface, as a result of the exchange of momentum between the object and its electromagnetic field.
The formula to calculate radiation pressure on a perfect absorber is
P = s/c, where
P = radiation pressure
s = intensity of light
c = speed of light
Now, on substituting the values and plugging it into the equation, we have
P = 34.5 / 3*10^8
P = 1.15*10^-7 N/m²
therefore, radiation pressure is found to be 1.15*10^-7 N/m²
Answer:
option D
Explanation:
The correct answer is option D
When verifying Kirchhoff's law we measure current.
Kirchhoff's law deal with current and potential difference.
This law was first described by the German Scientist Gustav Kirchhoff.
Kirchhoff's law stated the current arriving at the node is equal to the current moving out of the node.
Answer:
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged
One divides the volume by the density. You get

(or one liter, if you want)
