Design a thermal energy container that will keep 100 ml heat lamp for 0°C water as cold as possible under 50 minutes. The container will sit on a counter that will be approximately 130°C.

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 = 2.6 m below the tank bottom which is a = 6.7 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). report your answer in meters to two decimal places.

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (

Why do some scientists and archeologists think that volta was not the first person to build a battery
