What else can I help you with?
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...
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.
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.
