Which of the following experiments can be performed in an orbiting space station A. measure the density of the meteorite with a balance; B. observe the onion slices with a microscope; C. measure the temperature inside the chamber with a thermometer D the gravity of the object on the side of the spring dynamometer e the grip strength of the astronaut with the spring dynamometer

BCE, there is no gravity in space, so no matter which side of a weighs, it does not affect the state of the balance, and D cannot measure gravity



Find the attention and difficult problems about gravity in physics of grade two


(1) how long does it take to reach the ground?
(2) what is the displacement of the object within 1 s before landing? (g = 10)



What is the letter for volume?
