Answer:
a 25 m
b 25 m
c 35 m
Explanation:
(a)
Resultant displacdment is equivalent to the hypotenuse which is given by
Where x is displacement in East direction while y is displacement in North direction. Substituting 15 m for x and 20 m for y
H=25 m
(b)
The distance away from starting point is 15+20=35 m away following the path or 25 m as in a following the shortest route possible. It is clear that the hypotenuse is the shortest distance.
(c)
Distance travelled is 15+20=35 m
Answer:
property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
Answer:
Answer:
71.6°
Explanation:
According to the diagram
ED = 6 feet
DA = EB = 3 feet
AC = 15 feet
AB = ED = 6 feet
BC = AC - AB = 15 - 6 = 9 feet
Let the angle is θ from the horizontal
By the triangle EBC
tanθ = BC / EB = 9 / 3
tanθ = 3
θ = 71.6°
Thus, the angle from the horizontal is 71.6°.

Answer AND Explanation:
Fossil fuels are a type of naturally non-renewable energy sources that are formed from the remains of living organisms. The non-renewable resources are those that are not regenerated in nature at rates equivalent to their use. Fossil fuels have been used by man on a small scale for a long time. The main forms of fossil fuels are petroleum oil, natural gas and coal. Coal forms the major bulk of the fossil fuel deposits.
