You are doing an experiment outside on a sunny day you find the temperature of some sand is 28 degress celsius you also find the temperature of some water is 25 degrees celsius explain the difference in temperatures

What is the kinetic energy of a 10-kg bicycle moving at 10 m/s

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
