Answer:
9 meter per second square
Explanation:
acceleration equation is final minus initial velocity divided by time in seconds.
36-15/3=9 meter per second square.
Scientists have determined the temperature near the Earth's center to be 6000 degrees Celsius
Answer:
73 degree
Explanation:
Angle of incidence = 17 degree
According to the laws of reflection, the angle of incidence is equal to the angle of reflection.
So, angle of reflection = 17 degree
Angle from the surface = 90 - 17 = 73 degree
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.
