A merry-go-round of radius 2 m is rotating at one revolution every 5 s. A
child is located at 1 m from the axis. A teenager is located at 2 m from the
axis.
What is the angular speed of the child?
What is the angular speed of the teenager?
What is tangential speed of the child?
What is the tangential speed of the teenager?

Answers

Answer:

a) The angular speed of the child is approximately 1.257 rad/s

b) The angular speed of the teenager is approximately 1.257 rad/s

c) The tangential speed of the child is approximately 1.257 m/s

d) For the child, r = 2 m

The tangential speed of the teenager is approximately 2.513 m/s

Explanation:

The revolutions per minute, r.p.m. of the merry-go-round = 1 revolution/(5 s)

The radius of the merry-go-round = 2 m

The location of the child = 1 m from the axis

The location of the teenager = 2 m from the axis

1 revolution = 2·π radians

Therefore, we have;

The angular speed, ω = (Angle turned)/(Time elapsed) = (2·π radians)/(5 s)

∴ The angular speed of the merry-go-round, ω = 2·π/5 radians/second

a) The angular speed of the child = The angular speed of the merry-go-round = 2·π/5 radians/second ≈ 1.257 rad/s

b) The angular speed of the teenager = The angular speed of the merry-go-round = 2·π/5 radians/second ≈ 1.257 rad/s

c) The tangential speed, v = r × The angular speed, ω

Where;

r = The radius of rotation of the object

For the child, r = 1 m

The tangential speed of the child = 1 m × 2·π/5 radians/second = 2·π/5 m/s ≈ 1.257 m/s

d) For the child, r = 2 m

The tangential speed of the teenager = 2 m × 2·π/5 radians/second = 4·π/5 m/s ≈ 2.513 m/s

The blades of a metal cutter are shorter than the blades of paper cutter scissor. Give reason

Answers

Answer:

Metal is a tougher material to cut though, so the blades must be shorter to create more pressure to break through the metal. Paper on the other hand is easier to cut through so the blades can be longer in order to cut more in each snip.

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.Select the reason the author included the point that the remains found in the cave had been protected from the elements. aIt explains why people lived in the caves throughout history. bIt explains why researchers are trained to not disturb artifacts. cIt explains why the system is now a protected national park. dIt explains why they are great specimens for studying.
