Weegy: If a suitcase has a mass of 20 kg, The force of gravity acting on earth is 196N. Solution: force =mass *acc , force = 20 *9.8 = 196N. User: On the moon, what would be the force of gravity acting on an object that has a mass of 7 kg? Weegy: On the moon, the force of gravity acting on an object that has a mass of 7 kg is 11.2N. Solution: 7 kg * (1/6*9.8); 7 * 1.6 = 11.2 N User: On earth, what is a child’s mass if the force of gravity on the child’s body is 100 N? (More)

Weegy: The momentum of a 1,500 kg car traveling at 6 m/s is 9,000 kg m/s. = 1,500* 6 =9,000 User: A military airplane sometimes needs to refuel in mid-air, and another plane flies above it to add the fuel. If a plane with a mass of 7,800 kg is traveling with a velocity of 30 m/s and refuels by adding an additional 800 kg of jet fuel, what will its new velocity be? (Hint: This is a multi-step problem).

Weegy: The kinetic energy of an object that has a mass of 12 kilograms and moves with a velocity of 10 m/s is 600J ; kinetic energy = 1/2 mv^2 = 1/2 * 12 *10^2 = 1/2 * 12 *100 = 12 * 50 =600J. (More)

Weegy: Suppose a tank filled with water has a liquid column with a height of 10 meters. If the area is 2 square meters (m ), the force of gravity acting on the column of water is: F = Ahdg; F = 2 m2 ? 10 m ? 1,000 kg/m3 ? 9.8 m/s2; F = 20 ? 1,000 ? 9.8; F = 20,000 ? 9.8; F = 196,000 N. User: If a total force exerted by water in a container with a bottom area of 3 square meters is 900 newtons, what's the water pressure at the bottom of the container? Weegy: If a total force exerted by water in a container with a bottom area of 3 square meters is 900 newtons, 0.225k Pa is the water pressure at the bottom of the container. Solution: Force=450 N; A=2m^2; Pressure=Force/Area = 450/2 = 225N/m^2 = 225 pascal = 225/1000 kPa = 0.225k Pa (More)
