A spacecraft is on a mission to reach Mars, which is approximately million kilometers away from Earth. If the spacecraft travels at a constant speed of kmh how long will it take to reach Mars? Additionally, considering the gravitational influence of both Earth and Mars, determine the changes in velocity required to enter Mars' orbit from the spacecraft's trajectory.
Calculate the total energy required to melt kg of ice at C heat the water to C and then convert it to steam. Assume specific heat capacities of ice, water, and steam as kJkgC kJkgC and kJkgC respectively, and the latent heats of fusion and vaporization of water are kJkg and kJkg respectively.
A cylindrical tank with a height of meters and a diameter of meters is being filled with water at a rate of liters per second. Determine the time required to fill the tank. Also, calculate the pressure exerted at the bottom of the tank when it is full, considering the density of water as kgm and the acceleration due to gravity as ms
