Leon Bishop 2023-03-21 A science student is riding on a flat car roof train that is traveling at a constant speed of 10 mph on a straight horizontal track. The student throws a ball into the air along a path that he just made to make an initial angle of 60 degrees with the horizontal and to be in line with the track that the student's professor, who is standing nearby, observes the ball rising. How high does the ball rise vertically?

LoomiTymnk63x 2023-03-18 A heat pump is used to maintain a house at a constant temperature of 22degrees C. The house is losing heat to the outside air through the walls and windows at a rate of 40 MJ/J, while energy generated within the house from the people, lights and appliances amount to 6000kJ/h. For a COP of 2.4, find the power input to the heat pump

Finding good answers to the questions that are related to the physics of light and optics is not easy because these are mostly related to graphic experiments or multimedia experiments. Still, there are also verbal explanations that must be provided. When you need light and optics physics help, start with the verbal aspect of light and optics because if you cannot provide a solution in your own words, the graphs and lab experiments will not help you much. Once you get the text part, continue with the equations and the outcome of your research to get your paper structure accurate.
