Answer:

pollution causes smog

Smoke fog, or smog for short, is a type of intense air pollution.

it makes GHG wich is greenhouse gas and it makes the smog to stay inside the earth wich heats the Earth and it causes flood, storm, tornadoes, ect.

Which of the following can be represented by a single chemical symbol?

alisha [4.7K]

Answer:

Sodium

Explanation:

Sodium is a pure chemical, hence it can be represented by the single chemical symbol Na.

Water has a chemical symbol of H2O, consisting of two, and not one, symbols, H and O.

Sulfate ion consists of a sulfide ion and four oxygen ions (SO4)2-. Hence, it does not fit.

Finally, potassium chloride has a chemical symbol of KCl. Consisting of two different chemical symbols, (K and Cl), it does not fit either.

Hope this helped!

A sled is at rest at the top of a slope 2 m high. The sled has a mass of 45 kg. What is the sleds potential energy

wel

Answer:

$\boxed {\boxed {\sf882 \ Joules}}$

Explanation:

Potential energy can be found by multiplying the mass by the height by the gravitational acceleration.

$PE=mgh$

The mass is 45 kilograms. The height is 2 meters. The gravitational acceleration on Earth is 9.8 meters per seconds squared.

$m=45 \ kg \\h= 2 \ m \\g=9.8 \ m/s^2$

Substitute the values into the formula.

$PE=45 \ kg * 2 \ m * 9.8 m/s^2$

Multiply.

$PE=441 kg*m/s^2*2 \ m$

$PE= 882 \ kg *m/s^2 *m$

1 kg*m/s^² is equal to 1 Newton (N). Substitute N in for kg*m/s²

$PE=882 \ N*m$

1 Newton meter (N*m) is equal to 1 Joule (J). Our current answer is equivalent to 882 Joules.

$PE= 882 \ J$

The sled's potential energy is 882 Joules.
