Optical telescopes and radio telescopes on Earth can be used for remote observing. However, satellites equipped with gamma-ray and infrared sensors must be launched into space to observe distant objects. Explain why some remote-observing devices can operate from Earth but others must be launched into space.

Answers

Answer 1

Answer:

some objects are too far  or big to be fully observed from earth so the devices have to be launched, some devices are made to collect samples or bring astronauts into space.

Explanation:

Active sensors, provide their own source of energy to illuminate the objects they observe like ones on earth , An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or backscattered from the target.

Passive sensors, on the other hand, detect natural energy (radiation) that is emitted or reflected by the object or scene being observed. Reflected sunlight is the most common source of radiation measured by passive sensors. therefore some

Explanation:

The tilt of the earth's axis.

If you put a couple of toothpicks in an orange or an apple and make them so they are at a 45 degree angle and tilt the orange so it rotates on an axis made by the toothpicks, you will see how this works.

Turn off the lights and shine the orange with a flashlight. Now rotate it using the toothpicks as an axis. Go slowly. Notice how if you tilt the top toothpick towards the flashlight, it looks different than if make the top toothpick further away from the flashlight.

What you've done is exactly what the earth would do when its axis is closer to the sun and further away from the sun.

I hope this is clear enough.

What is  weather?

Weather refers to the state of the atmosphere and includes terms like how hot or cold, wet or dry, quiet or stormy, clear or foggy, etc. The troposphere, which is the lowest part of Earth's atmosphere and lies just below the stratosphere, is where most meteorological events take place.

Climate is the phrase for the averaging of atmospheric conditions over longer periods of time, whereas weather is the term for day-to-day temperature, precipitation, and other atmospheric factors. Without more explanation, "weather" is typically taken to refer to the weather on Earth.

Differences in air pressure, temperature, and moisture from one location to another influence the weather. The Sun's angle at any given location, which changes with latitude, may be the cause of these variations.

List 10 ways you can prepare for an earthquake. What should you do during an
earthquake?

Answers

Answer:

   Have a plan. Create a communications plan with your family and establish a meeting place to ensure that family members are accounted for.

   Check for hazards in your home. Make sure to fasten shelves securely to walls, move heavy items such as pictures and mirrors away from beds and repair any structural defects.

   Purchase bottled water. It is important to have at least one gallon per person per day for three to 10 days to be used for drinking and cooking.

   Store foods that require little preparation. Canned foods, granola bars and vacuum sealed foods are good choices because they do not require refrigeration and have long shelf lives. Don’t forget to include food for your infants and pets.

   Be sure to include personal hygiene products, supplies and a first-aid kit. Items such as blankets, tarps, toilet paper, moist towelettes, scissors, lighters, a can opener, fire extinguisher, crank radio, flashlight, etc. should also be included.

   Don’t forget medication. If you or a family member is dependent on prescription medication, make sure to include a month’s supply in your emergency kit.

   Make copies of important documents and a set aside a small amount of cash. When large natural disasters strike, Internet access may not be possible and electronic bank cards may not work.

   Keep your gas tank full. In the event of an emergency, it may be difficult to fill up your tanks. Try not to let the gas tank in your car get below a half tank.

   Prepare a small emergency kit for your car. You could be on the road when a large earthquake hits. Use a backpack to store a supply of food, water, walking shoes and first aid items.

   If you experience an earthquake, conduct a home safety check. Immediately following an earthquake, it is important for you to check for downed power lines, water and gas leaks. Make sure that you have a wrench in your supply kit and know how to shut off your electricity, water and gas if necessary.
