Achunk of iron weighing a few kilograms flies into the inner solar system, is captured by earth's gravity, enters the atmosphere burning brightly, and lands on solid ground. three different names apply to the different stages of its journey. place them in order from first to last.

Explanation:

Meteoroid: A small part of a comet or asteroid that orbits the Sun.

Meteor: the light occurrences resulting from a meteoroid entering and vaporizing the Earth's atmosphere;  for example a shooting star.

Meteorite: A meteoroid that completes its journey through the atmosphere of the Earth and lands on the surface of the Earth.

So, When the chunk of iron was flying in spaces and attracted by the Earth's gravity is called Meteoroid.

When it entered the atmosphere burning brightly it is called Meteor.

The solid part that lands on the ground is called Meteorite.

a) 4500 cycles.

b) (1/15) s = 0.0667 s

c) (20/3) s = 6.667 s

Explanation:

The blades on a fan have a frequency of 15 Hz

This means the number of cycles completed per second = 15

a) How many cycles do the blades complete in five minutes?

5 mins contains 5 × 60 seconds, that is, 300 seconds.

The fan completes 15 cycles in 1 second

In 300 seconds, it will complete

15 × 300 cycles = 4500 cycles.

b) What is the period for the fan blades?

Period = (1/frequency)

= (1/15) = 0.0667 second per cycle.

c) How long would it take for the fan blades to complete 100 revolutions?

This means how long would the fan complete 1 cycle as 1 rev = 1 complete cycle.

The fan complete 1 cycle in (1/15) second

The fan will complete 100 cycles in (100×1/15) =

(20/3) s = 6.667 s

Hope this Helps!!!
