Following are the correct options for this question:
- Build more windmills
- Develop cost-efficient solar energy
- Improve gas mileage in cars
- Reduce the use of nonrenewable energy sources
Any undesirable change occurs in the air due to addition of pollutants is called air pollution. The major air pollutants are sulfur dioxide which is released from the combustion of fossil fuels like coal, petroleum and from factories. Bedsides, sulfur dioxide dust and smokes are other pollutants. Building of more wind mills and developing low cost solar energy will reduce air pollution as they will provide clean energy and will reduce dependency on coal burning in thermal power plant. Improving as mileage in cars will also reduce emission of sulfur dioxide, hence reduce air pollution. Building of more wind mills and developing low cost solar energy are renewable source of energy, will reduce use of nonrenewable energy sources such as fossil fuels.
Answer: We study other star systems in spaceships and big, professional telescopes

Scientists want to place a telescope on the moon to improve their view of distant planets. The telescope weighs 200 pounds on earth. The weight of the telescope when it reaches the moon as the weight of the telescope will be equal to its mass.
If you're trying to view faint deep-sky items like nebulas and galaxies then you'll need a reflector telescope while a refractor telescope is higher suited for perspectives inside our very own galaxy consisting of the moon and other planets.
A telescope is an optical tool using lenses, curved mirrors, or a mixture of each to look at remote objects, or diverse gadgets used to observe distant gadgets by means of their emission, absorption, or mirrored image of electromagnetic radiation.
The Celestron encourage 100AZ is a top, top choice of telescope for beginners. It gives remarkable ease of setup and use, and it comes with a much greater choice of add-ons than most other starter telescope bundles - it's the entire package for the ones trying their hand at astronomy.
