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.

5, sorry this is the answer but i need more words hah




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.

Read the passage:A cave system is actually not one single cave but a series of connected caves. The Mammoth Cave in Kentucky is the longest cave system in the world. The system is remarkably stable because it is made of limestone that is covered by a layer of sandstone. There are more than 405 miles of passageways that weave through the massive cave system. Every year, new caves and connections are discovered.Several North American tribes have been known to settle in the cave system throughout history. Scientists have been researching the people that had once called the cave system home. The remains found in the cave had been protected from the elements, which makes them great specimens for studying. They are so well preserved that scientists can easily study the people's dietary habits. This research has found that the people living in the cave were once hunter-gatherers, and then they transitioned to a community with domestic plants and agriculture. That means they learned how to grow their own food instead of having to hunt for it.Researching in this type of environment is tricky business. Moving an artifact even a little can diminish its research value. That is why explorers are trained to not disturb artifacts they find. They learn how to collect and study the items they find without spoiling them. It is because of this sensitivity that the cave system is protected and is now a national park.What evidence does the author use to support the idea that the cave system is stable?It is made of limestone that is covered by a layer of sandstone.A cave system is not one single cave but a series of connected caves.Every year, new caves and additional connections are discovered.There are more than 405 miles of passageways within the cave. 3.
