Read the paragraph below and answer the question that follows:
for most of their lives, stars fuse elemental hydrogen into helium in their cores. two atoms of hydrogen are combined in a series of steps to create helium-4. these reactions account for 85% of the sun’s energy. the remaining 15% comes from reactions that produce the elements beryllium and lithium. infer which element is the most common in a star such as our sun.
question 6 options:
a. hydrogen because it takes 2 hydrogen atoms to make helium
b. helium because it is constantly being made in the sun
c. beryllium because it accounts for 15% of the energy
d. lithium because it's smaller than beryllium

What makes thermal imaging cameras useful? they can detect differences in color. they can detect differences in wave speeds. they can detect differences in temperature. they can detect mechanical waves.

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
