Answer:
The average death rate for this type of event is closest to 350 people per event.
Explanation:
Between the years 2048 and 2057
Is 10 years. Since there is only one chance of event between these years, there is no point to consider it.
The total number of events = 2940 chances.
average death rate per event = total number of dead people divided by total number of events of occurrence.
1000000/2940 = 340.134
The average death rate for this type of event is therefore closest to 350 people per event
The process in which water vapour and carbon dioxide
traps heat is called the “greenhouse effect”.
The greenhouse effect is a natural phenomenon which
occurs every day. To illustrate an example of this natural phenomenon, d<span>uring the day the Sun shines through the atmosphere.
Earth's surface warms up because of the sunlight. Meanwhile at night in the
absence of the sunlight, Earth's surface cools back and releasing the heat back
into the air. However some of the heat is retained by the greenhouse gases
(such as carbon dioxide and water vapour) in the atmosphere. This process what
keeps our planet Earth warm and cozy at an average temperature of 16°C.</span>

Answer:
a) 
& 
b) 
c) 
Explanation:
Given:
mass of the book, 
combined mass of the student and the skateboard, 
initial velocity of the book, 
angle of projection of the book from the horizontal, 
a)
velocity of the student before throwing the book:
Since the student is initially at rest and no net force acts on the student so it remains in rest according to the Newton's first law of motion.
where:
initial velocity of the student
velocity of the student after throwing the book:
Since the student applies a force on the book while throwing it and the student standing on the skate will an elastic collision like situation on throwing the book.
where:
final velcotiy of the student after throwing the book
b)
c)
Since there is no movement of the student in the vertical direction, so the total momentum transfer to the earth will be equal to the momentum of the book in vertical direction.
