Answer: Volume
Explanation: Volume is the amount of space matter takes up. All matter takes up a certain amount of space. Volume is used in mathematics and science all the time to describe the size of a particular object.
An example of volume would be finding the volume of a cube with a length of 30 feet.
Since the length, width, and height of a cube are all equal, we can find the volume of a cube by multiplying the side × side × side or S³.
(30 ft)³
Volume = 27,000 ft³.
Answer:
the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.
Explanation:
According to Newton's second law, when the same force is applied to two objects of different masses, the two objects will change mass.
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.
