Answer: Either electromagnetic radiation or energy is the answer to your question.
Isaac Newton was experimenting with prisms and discovered that all light is made up of the colors of the rainbow.
The correct answer is A.
Answer: C. Africa
Explanation:
The data given on the graph shows that:
Asia will grow from around 1,300 million to 5,000 million in 2050 which is an increase of:
= 5,000 /1,300 = 3.84 times
Europe will decrease over that period.
Africa will go from around 300 million to 2,000 million which is an increase of:
= 2,000 / 300
= 6.67 times
Mexico
, Central America, Caribbean Islands:
= 900 / 120
= 7.5 times
United States, Canada, and Greenland:
= 400/120
= 3.33
Oceania:
= 50 / 13
= 3.85
From the options give, Africa will see the greatest increase at 6.67 times its population in 1950.
Iron is the solvent and carbon is the solute.
Answer:

Explanation:
The time the stone takes to fall can be calculated considering only the vertical component with the formula:

Taking the inital height as 0m and downward direction positive, since it departs from (vertical) rest we have:

Which gives us a time:

Horizontally, on that time the stone travelled a distance x=10m, which means its horizontal speed was:

Since <u>this speed is the tangential velocity</u> while whirling, the centripetal acceleration of the stone was:
