We measure distances in astronomy in terms of AU which is the distance between the earth and sun. If the distance is 2AU, it is twice that distance.
What happens to the time period (1 year) for planets when you double the
distance from the sun? (approximately)

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
