Which of the following is true about the astronaut in the picture? Weight on Earth:
100 kg
Weight on Moon:
16,6 kg
A The astronaut's weight changes depending on magnetic fields.
B) The astronaut has the same mass on the Earth and on the moon.
The astronaut weighs less on the moon because there is no oxygen
D The astronaut's mass changes depending on how much the moon weighs.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
