Abicycle takes 8.0 seconds to accelerate at a constant rate from rest to a speed of 4.0 m/s. if the mass of the bicycle and rider together is 85 kg, what is the net force acting on the bicycle

When a neutral charge, comes into contact with a positive charge they repel each other nothing happens the neutral charge becomes negative they attract each other

In physics the desire of an object to keep doing what it is doing is termed?

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)
