The hottest day on Mars is 20 degrees Celsius at the equator. The night can go up to minus 153. The latter is characterized by strong dust storms. The surface appears to be dry but water is expected to flow to the bottom. Take a look at the day given by the vehicles that landed…
Infrared radiation from a black body is analyzed and used to determine its temperature. The object is seen in the color of brass. Activity. First, the pressure is reduced by means of a vacuum pump. The temperature is then reduced with liquid nitrogen. The black body is then placed in front of the source. The…
Look at the two pictures given to make this clear. The first is when someone throws a stone. The velocity of the stone is shown as two elements, vertical and horizontal. Since there is no force in the opposite direction to the coastal component, the stone travels away until it falls to the ground. As…
