Answer:
θ = 51.21°
Explanation:
Vh= 193.6 km/h
Va= 141.7 km/hr
Relative velocity ,Vr= 193.6 - 141.7 = 51.9 km/hr
Time taken to cover 71.3 m
t= 3.81 s
t= 0.00105 hr
So the horizontal distance x
x= Vr .t
x= 51.9 x 0.00105 km
x=0.0549 m
x= 54.96 m
Lets take angle is θ
tan θ = h/x
tan θ = 71.3/54.96
θ = 51.21°
The size of the force exerted on the car is larger than the force the car exerts on Earth. Gravity is acting on the car but the car is moving perpendicular to the motion of gravity. So it is exerting almost no force on Earth.
Answer:
The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards. The displacement can also be negative. An area beneath the x-axis has a negative value.
The order of the location of each process in the carbon cycle are as follows;
- <u>Ingestion → Decomposition → Fossilization → Combustion </u>
Reasons:
Ingestion; During the ingestion process, the products of the direct Sunlight and photosynthesis, which
are energy rich chemical substances are ingested by herbivores.
Decomposition; The plants and animals die and undergo decomposition.
Fossilization; A long period the decomposed plants and animals manifest
into hard petrified materials, with their parts transformed to fossils.
Combustion; The remains of plants and animals, subjected to heat and
pressure due to compression, as when as bacteria decomposition that
removes several other elements, leaving a carbon and hydrogen rich
sludge that can be processed into fuel used for combustion. The
combustion process produces carbon dioxide which restarts the cycle.
