We have,
- The mass of sally's mug is 1 kg
- The pressure appliedby the mug is 1100 pascal.
We know that,
As, we already have the value of pressure, let's calculate that of force now;
- F = ma
- F = 1 × 9.8 { Acceleration due to gravity, let's round off it to 10}
- F = 10 N
Just put all the values in the formula now;
- P = F/A
- 1100 = 10 / A
- 1100/10 = A
- 110 m² = A
As, it is already mention that we need to find the radius of the mug, it is obviously a circular base.
We know that,
- Surface area = Circumference
So, let's solve it;
- Circumference = 2πr
- 110 = 2 × 22/7 × r
- 110 × 7/2 × 22 = r
- 5 × 7 = r
- 35 cm = r

I would assume gamma rays because they have the fastest moving partials out of all of them
Answer:
A
Explanation:
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
Answer:
Herpetology is the branch of zoology concerned with reptiles and amphibians.
