SCIENTIFIC DISCOVERIES
A satellite is best understood as a projectile, or an object that has only one force acting on gravity. Technically speaking, anything that crosses the Karman Line at an altitude of kilometers (62 miles) is considered in space. However, a satellite needs to be going fast — at least 8 km (5 miles) a second - to stop from falling back down to Earth immediately.
If a satellite is traveling fast enough, it willperpetually"fall" toward Earth, but the Earth's curvature means that the satellite will fall around our planet instead of crashing back on the surface. Satellites that travel closer to Earth are at risk of falling because the drag of atmospheric molecules will slow the satellites down.Thosethat orbit farther away from Earth have fewer molecules to contend with.
There are several accepted "zones" of orbits around the Earth. One is called low-Earth-orbit, which extends from about 160 to 2,000 km (about 100 to 1,250 miles). This is the zone where the ISS orbits and where the space shuttle used to do its work. In fact, all human missions except for the Apollo flights to the moon took place in this zone. Most satellites also work in this zone.
Geostationary or geosynchronous orbit is the best spot for communications satellites to use, however. This is a zone above Earth's equator at an altitude of 35,786 km (22,236 mi). At this altitude, the rate of "fall" around the Earth is about the same as Earth's rotation, which allows the satellite to stay above the same spot on Earth almost constantly. The satellite thus keeps a perpetual connection with a fixed antenna on the ground, allowing for reliable communications. When geostationary satellites reach the end of their life, protocol dictates they're moved out of the way for a new satellite to take their place. That's because there is only so much room, or so many "slots" in that orbit, to allow the satellites to operate without interference.
While some satellites are best used around the equator, others are better suited to more polar orbits - those that circle the Earth from pole to pole so that their coverage zones include the north and south poles. Examples of polar-orbiting satellites include weather satellites and reconnaissance satellites.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
The British are particular about timings and being late is frowned upon, but being on time is a complicated matter because in some situations, being a few minutes early on others means being exactly on time and in some instances, it is completely acceptable to arrive 10 minutes to a few hours later than the stated time. This can be a minefield for someone who is new to the UK, so here are some basic rules that will help you get your timing right whatever the situation.
In formal meetings, such as job interviews, you should arrive at least five minutes before your meeting. This will give you time tocomposeyourself before your big meeting. In the UK, arriving late for a formal meeting is seen as unprofessional and will reflect badly on you. If you are running late, ring your host to let them know you will be late. On arrival, apologize sincerely and offer a reason for your lateness, such as you got lost or the train was delayed. It will help you redeem yourself. However, if you are late because you set off later than you should have, it's wise to keep that to yourself!
If you have been invited to a dinner party, you should arrive exactly on time as the host will have planned when they will serve the food. You will find that your host will serve their guests a pre-dinner drink, so that gives you a bit of wiggle room, but if you are running later than 10 minutes, you should ring your host and let them know how late you might be.That waythey can decide whether to go ahead and serve the other guests. When you arrive you should offer the host and the other guests your apology for being late.
