A loaf of bread weighs 2.3 N on Earth. What should it weigh, in newton's, on the moon, where the acceleration due to gravity is one-sixth that on Earth? What should it weigh on Jupiter, where g is 2.64 times Earth’s gravity?

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles. (1 mi = 5280 ft) g
