Answers

Answer: the rider’s pedal force must be greater than friction and the force of gravity

Explanation:

This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.

During the second week of the lunar cycle, the moon is seen as a waxing gibbous, which appears as a mostly illuminated disc with a small portion of darkness on one side.

What is lunar cycle?

The lunar cycle, also known as the lunar phase or the phases of the moon, refers to the regular and predictable changes in the appearance of the moon as seen from Earth.

The lunar cycle is driven by the changing relative positions of the Earth, moon, and sun, and it typically lasts approximately 29.5 days. During this time, the moon goes through a sequence of eight different phases, including new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, and waning crescent, before returning to the new moon phase.
