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.
It is a state with very little population and/or small land area
The answer is true (a) because if the life cycle suddenly doesn't work, this will have an impact on all other organsims
In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
Pressure = Force / Area
It is also to be noted that force is the product of mass and acceleration due to gravity.
Force = mass x acceleration due to gravity
Substituting,
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, substitute this to the first equation,
Pressure = 3430 N / 1m²
<em>ANSWER: Pressure = 3430 N/m² = 3430 Pa</em>
Yes they do occurs in certain features
