The Kyoto Protocol, which limits emissions of greenhouse gases for developed nations, is an example of international Law
Explanation:
The Kyoto Protocol is named after a Japanese city in which it was executed in the year 1997 on 1st December.
The basic aim of the Kyoto Protocol is to reduce/Limit the emission of greenhouse gases which contributed to global warming
The Protocol was linked to the United Nations Framework Convention on Climate Change (UNFCCC)
The important factor that led to the failure of Kyoto's Protocol are deficiencies in the structure of the agreement, such as the exemption of developing countries from reductions requirements, or the lack of an effective emissions trading scheme
Answer:
Vf = 21.5 [m/s]
Explanation:
To solve this problem we must use the following kinematics equation:
where:
Vf = final velocity [m/s]
Vi = initial velocity = 0
a = aceleration = 4.3 [m/s^2]
t = time = 5 [s]
Now replacing:
Vf = 0 + (4.3*5)
Vf = 21.5 [m/s]
Answer:
123.48J
Explanation:
Given parameters:
Mass of the ball = 2.8kg
Height = 4.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy due to the position of a body. It is mathematically given as;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now insert the parameters and solve;
P.E = 2.8 x 4.5 x 9.8 = 123.48J
