Joshua was driving to a friend’s house to study. During his trip, he started on pavement. At one point, he hit an ice patch on the road, but then he returned to pavement. The road then turned into a gravel road.

Which best describes the frictional force of his trip?

Friction increased when he went from pavement to ice and then decreased two more times.
Friction decreased when he went from pavement to ice and then increased two more times.
Friction increased when he went from pavement to ice and then decreased one additional time.

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
