Answer:
C. Just measure the volume of the container it is in
Explanation:
Another why of measuring the volume of gas is by filling a contractor with water then in invert a glass jar air will miss place the space taken by water then measure the volume of water misplaced to get the volume to air
Answer:
Part a)
Work done is given as
W = -121.5 J
Part b)
Potential energy of the system is given as
Explanation:
As we know that work done by variable force is given as
here we know that
so we have
so we have
here we displace it from x = 2 to x = 5
so we will have
Part b)
As we know that change in Potential energy = work done
Hello!
Recall the equation for gravitational force:
Fg = Force of gravity (N)
G = Gravitational constant
m1, m2 = masses of objects (kg)
r = distance between the objects' center of masses (m)
There is a DIRECT relationship between mass and gravitational force.
We are given:
If we were to double one mass and triple another, according to the equation:
Thus:
