1. To calculate the volume of the pool you need to convert the length, width and height into one same unit. The volume would be:
volume= length * width * height
volume= 50m *25m *(48ft *0.3048m)= 18288m^3
volume in gallons= 18288m^3 * (264.172 gallons/m^3)= 483.118 gallons
2. The mass would be found by multiplying density with volume. You will need to some unit conversion to get the mass in kilogram. Remember that 1g= 1000kg and 1m^3= 1,000,000ml
mass= volume * density
mass= 18288m^3 * (10^6 ml^3/m^3) * 1.0 g/mL / (1000g/kg)= 18,288,000 kg

The difference between speed and velocity is that speed is the time rate at which an object is moving along a path. While velocity is the rate and direction of the object’s movement.
if something is travelling at a constant velocity are the forces balanced or unbalanced?
Unbalanced
if something changes motion, are forces balanced or unbalanced?
Unbalanced. If the forces on the object is equal and in opposite directions, then the forces are balanced, then there would be no change in motion
what are the three ways to accelerate?
1. A change in velocity
2. A change in direction
3. A change in both velocity and direction
Respiratory system and circulatory system both are responsible to control the breathing in Human body.
Types of matter are just different ways molecules behave at certain temperatures. There's no specific atoms or molecules that make solids, liquids, or gases. Ice, water, and water vapor are all H2O, for instance. The only correct answer would be that it is made of the same basic particles, but then again, so is everything.
