A 6 kg red ball is moving at 4 m/s along the positive x-axis. The red ball elastically collides with a stationary 3 kg blue ball. After the collision, the red ball is traveling 2 m/s at 300° from the x-
axis. What is the magnitude of the blue ball's total final velocity?

the answer is the last option

explanation:

because in order to know what the molecule is you need to know how many atoms of each element are in the molecule.

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
