IF the hot air in aballon
have a density equal to 3/4
minimum ballon volume is required to lift a total load of 500kg the density of air at 0°c at the atmospheric pressure is 1.29kg/m^3

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
