Which sentence explains why optical land telescopes are not able to take images as clear as those taken by the hubble space telescope?
hubble takes pictures of planets, stars, and galaxies. the mixture of gases that surround a planet is called its atmosphere. earth’s atmosphere changes and blocks some of the light that comes from space. hubble orbits high above earth and its atmosphere. so, hubble can see space more clearly than telescopes on earth can. hubble is not the kind of telescope that you look through with your eye. hubble uses a digital camera to take pictures. then, hubble uses radio waves to send the pictures through the air back to earth.

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
