What would be the density of a twenty gram object that displaces four millimeters of water?
To calculate the density of the object, you need to divide the mass of the object by the volume of water it displaces. Since water has a density of 1 g/mL, 4 millimeters of water is equal to 4 grams per square centimeter. Therefore, the density of the object would be 20 g / 4 cm^3 = 5 g/cm^3.

What is the density of a block of aluminum that has a mass of twenty seven grams and a volume of ten centimeters to the third power?
Density = (mass) / (volume) = 27/10 = 2.7 gm/cm3 .

If the radius of the Earth is made 5 times bigger will an object on its surface weight one twenty fifth times as much?
The law of universal gravitation states that F = G(M1M2)/(r squared). Assuming that the mass of the Earth did not also increase proportionally, then the force of gravity would be 1/25th as much.
How would you make something that stays under water for at least twenty seconds then floats back up?
Maybe use the same principal as a submarine. Two water tanks begin to fill themselves with water, and therefore the craft sinks. Then, after your twenty seconds, a pump should begin to remove the water from the water tanks, causing the craft to float back to the surface. If the army have faith in this simple physics then I'm sure we can...
A cart pushing ten bricks or a cart pushing twenty bricks using the same force and going the same distance which has greater kinetic energy?
The same force could not be applied to travel the same distance if there is a larger mass in one instance. Applied force will accelerate a given mass twice as much as a mass half as large. If both are moving the same distance, the 20-brick cart had more kinetic energy when in motion.
Which object has the greatest density twenty kilograms of cement twenty kilgrams of feathers twenty kilograms of paperclips twenty kilograms of plastic bottels?
The object with the greatest density is the 20 kilograms of cement, as cement is a dense material compared to feathers, paper clips, and plastic bottles. Density is a measure of how much mass is in a given volume, so the denser the material, the greater the density.
