Answers

To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.

Adam applies an input force to the pulley as he pulls down to lift the object. As he does this, Adam wonders about how the pulley is helping him. How is the pulley helping Adam lift the object?a. All of these answers are correct.
b. A fixed pulley lowers the amount of force needed to do the same amount of work.
c. A fixed pulley increases the distance over which the force is applied.
d. A fixed pulley helps Adam change the direction of the effort force.

Answers

Explanation :

Adam applies an input force to the pulley as he pulls down to lift the object. As he does this, Adam wonders about how the pulley is helping him.

A pulley is a simple machine which always changes the direction of effort forces. It consists of a rope and a wheel.

The pulley can be of three types i.e. a fixed pulley, movable pulleys and combined-pulley systems.

Hence, the correct option is (d) " A fixed pulley helps Adam change the direction of the effort force ".
A fixed pulley changes the direction of the effort force, but not its magnitude.

Final answer:

The federal UST regulations typically do not cover tanks that store heating oil used on site, tanks that hold less than 200 gallons, and farm and residential tanks that hold 2,000 gallons or less of motor fuel for noncommercial uses.

Explanation:

The question pertains to certain types of storage tanks that are exempt from federal regulations called USTs (Underground Storage Tanks). These tanks are used to store regulated substances, typically petroleum and hazardous substance. However, not all tanks fall under these regulations. For instance, tanks that store heating oil used on the premises where it is stored, tanks that hold less than 200 gallons, and farm and residential tanks that hold 2,000 gallons or less of motor fuel for noncommercial uses, are not governed by these federal UST regulations. Hence, the correct answer is D) all of these.

Which is the correct order of events in the water cycle?

Answers

Answer:

1. Evaporation: The water evaporates from the water  bodies like seas and oceans.

Transpiration: The water evaporates from the plant's leaves.

2. Condensation: The evaporated water condenses to liquid droplets which to form clouds.

3. precipitation: When the cloud becomes heavy, water rains down. This is known as precipitation.

The water rains down in rivers and seas and oceans. From rivers, it runs off back into the seas.
