Oil is a compound.

The species which contain more than one element is called compound. Oil is a mixture of many elements like liquid hydrocarbons, oxygen, nitrogen, sulphur, hydrogen gas etc. This elements form a large variety of structure.

In a Broadway performance, an 83.0-kg actor swings from a R = 3.90-m-long cable that is horizontal when he starts. At the bottom

Veseljchak [2.6K]

Answer:

$h = 2.821\,m$

Explanation:

The speed of the actor before the collision is found by means of the Principle of Energy Conservation:

$(83\,kg)\cdot(9.807\,\frac{m}{s})\cdot (3.90\,m) = \frac{1}{2}\cdot (83\,kg)\cdot v^{2}$

$v = \sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot (3.90\,m)}$

$v \approx 8.746\,\frac{m}{s}$

The speed after the inelastic collision is obtained by using the Principle of Momentum Conservation:

$(83\,kg)\cdot (8.746\,\frac{m}{s} )+(55\,kg)\cdot (0\,\frac{m}{s} ) = (83\,kg + 55\,kg)\cdot v$

$v = 5.260\,\frac{m}{s}$

Lastly, the maximum height is determined by using the Principle of Energy Conservation again:

$\frac{1}{2}\cdot (138\,kg)\cdot (5.260\,\frac{m}{s} )^{2} = (138\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot h$

$h = \frac{(5.260\,\frac{m}{s} )^{2}}{9.807\,\frac{m}{s^{2}} }$

$h = 2.821\,m$

Why is it warmer near the equator and cooler near the poles?

Phantasy [73]

It is because the equator is closer to the sun and because the sun's rays hit the surface of the Earth at a higher angle at the equator. The poles are colder because they don't get direct sunlight. The sun is always low on the horizon.
