Answer;
- This statement about matter and its behavior is best classified as a Law.
-It is the Law of Universal Gravitation.
Explanation;
-The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation.This attractive force always points inward, from one point to the other.
-The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric.
vacuum walls: prevents heat loss by comduction and radiation
silvered walls prevent loss by radiation
ceramic base prevents loss by conduction
cap prevents by radiation and convection and reduces by comduction
You have:
A1= 0.15 m²
A2=6.0 m²
F1=130.0 N
To solve this problem you must use the pressure formula, as below:
P1=P2
F1/A1=F2/A2
Then, you have:
m2=A2xF1/A1xg
g=9.81 m/s² (This is the acceleration of gravity)
When you substitute the values in m2=A2xF1/A1xg, you obtain:
m2=(0.60 m² x 130.0 N)/(0.15 m² x 9.81 m/s²)
The answer is:
m2=530 Kg
In order to compare the two temperatures, we need to convert 20°F into Celsius. The formula we need to use is:
Substituting 20°F, we find
And this is less than 0°C, so the answer is
20°F is colder than 0°C.
