A garden hose attached with a nozzle is used to fill a 20-gal bucket. The inner diameter of the hose is 1 in, and it reduces to 0.5 in at the nozzle exit. The average velocity in the hose is 8 ft/s. The volume flow rate of water through the hose

What object a collides with object b and bounces back its final momentum is?

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
