Why do cats have tails?
tester [92]
Cats have tails to help their balance. Similar to the stick a trapeze/high wire walker uses.

The tail helps to serve as a counterbalance when cats walk on narrow spaces such as fences or shelves. The tail also aids in balance when a cat is running after or jumping on prey.

Just so you know....Cats can live without tails.

Which of the following is NOT an illuminated object?
Korolek [52]

Answer:

The answer here would be light bulb.

Explanation:

An Illuminated object is simply something that reflects light. And everything in the list is illuminated except the light bulb. Humans reflect light in the same way as desks and sidewalks. If we didn't we wouldn't technically be able to see other humans unless they were luminous. This brings me to the nest point. A light bulb is a luminous object because <em>it creates light on its own. </em>

A good example would be this:

The Sun is a luminous object

The Moon is a illuminated object

I hope this helped and didn't confuse you more, I kind of went all over the place with the explanation. Either way, if you need more help feel free to let me know! :)

Famed stunt pilot, Cleonvia Thread, pulls out rapidly from a dive. He is traveling at 222 mi/h at the bottom of his trajectory,
Simora [160]

Answer:

0.39 m/s²

Explanation:

From the question,

a = v²/r.................... Equation 1

Where v = velocity, r = radius.

Given: v = 222 mi/h = (222×0.44704) m/s = 9.83 m/s, r = 820 ft = (820×0.3048) m = 249.94 m.

Substitute thses values into equation 1

a = 9.83²/249.94

a = 96.63/249.94

a = 0.39 m/s²

Hence the  acceleration is 0.39 m/s²
