Start with the Half-Life tab. Press the pause button. Then, press Add 10 one time to add 10 atoms of carbon-14. Next. press the play button and watch the timeline at the top of the screen.

Press Reset All Nuclei, and watch the timeline again. Repeat this process several times.

When do the C-14 atoms decay on each repetition?

O always after the half-life mark

O always before the half-life mark

O at random times

O at the same time

O in 1,000-year intervals

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.

Which scenario is most similar to the type of collision that gas particles have according to kinetic molecular theory

The famous scientist galileo galilei did several experiments with sloping planes, which he rolled metal balls down so that he could study motion. by changing the slope, he could study how the speed at which the ball rolled was affected. what was the independent variable in galileo's experiment? a. the speed of the ball b. the slope of the plane c. whether the ball moved d. what the ball was made of
