PLEASE HELP AND I WILL GIVE BRAINLIESTA science textbook with the mass of 5 kg is dropped from the shelf 2.5 m high what is the velocity of the book right before it hits the ground?

Aforce of 240.0 n causes an object to accelerate at 3.2 m/s2. what is the mass of the object?

Rohit is trying to tune an instrument

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)
