1)
the sun, on average,is 93 million miles from earth. how many meters is this? Express (a) using powers of 10, and (b) using a meteric prefix(km)

2)
A light-year is the distance light travels on one year (at speed=2.998x10^8m/s). a) how many meters are there in 1.00 light year? b) an astronomical units (AU)is The average distance from the sun to earth 1.50x10^8km. how many AU are there in 1.00 light -year ?




Solutions

Expert Solution

1. In1 miles there is 1609.34 m,

Then in 93×10^6 miles there is 1609.34×93×10^6 m =149668.62×10^6 m.

Therefore distance between sun and earth is 1.49×10^11 m.

2. Light year is the distance travelled by the light with the speed v=2.998×10^8m/s for time of one year.

A block of mass 4kg is dropped from a height of 2 meters on Earth. If that block is taken to a different planet, where the acceleration due to gravity is 1/4 as strong as it is on Earth, how high should the block be dropped so that it hits the ground with the same final velocity as on Earth? (Hint: you do not need to use gravitational force for this) Express your answer to a maximum of 2 significant...
