Aboy drops his toy off the bunk bed. the distance to the floor is 2.5m. it takes one second to reach the floor. gravity accelerates objects on earth at 9.8m/s square. the earth's gravity applies 50 newton of force to the toy? what is the toy's mass?

Hey student studies gravity using objects that have the same mass which two objects have the greatest gravitational force acting between them a. 100kg 1.0m 100kg b. 100kg 2.0m 100kg c. 100kg 2.0m 100kg big d. 100kg big 3.0m 100kg big

What is the temperature in degrees celsius of a substance with a tempature of 49k

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
