Kinetic energy is energy in motion and potential energy is stored energy
Answer:
24.24L
Explanation:
According to Boyle's law which states that "the volume of a given mass of gas at constant temperature is inversely proportional to its pressure". Mathematically, P = k/V where;
P is the pressure
V is the volume
k is the proportionality constant
PV = k
P1V1 = P2V2
P1 and P2 are initial and final pressure respectively
V1 and V2 are the initial and final volume respectively
Given P1 = 101kPa V1 = 6.0L, P2 = 25kPa V2 = ?
From the formula;
V2 = P1V1/P2
V2 = 101×6/25
V2 = 24.24L
The final volume for the gas is 24.24L
We will use the formula p = mgh
p is potential energy.
m is mass of object in kg
g is acceleration due to gravity (9.8m/s²)
h is height of the objects displacement in meters.
p = mgh → mgh = p → h = p / mg
p is 14000j, m is 40kg and g is 9.8 m/s²
h = 14000 / 40 × 9.8 → h = 1400 / 392 → h = 35.7
Therefore , the cannonball was 35.7 meters high .
Answer:
2400 cm
Explanation:
The milky way has diameter of 100000 light years.
The local group is the collection of galaxies which includes the milky way.
10 million light years is the diameter of the local group.
Hence, the diameter of the scale model of the local group would be 2400 cm
