An Olympic-size pool is 50.0 m long and 25.0 m wide.
Lostsunrise [7]
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

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

52. Which is true about all the different types of matter?
Svetllana [295]
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.
