Answer: 20 newtons
Explanation:
Given that:
Force applied by Samantha = 10 newtons
Force applied by Emily = 10 newtons
Direction of both forces = same
Net force of their efforts = ?
Since net force of forces applied in the same direction is obtained by adding up the seperate forces applied, then
Net force = (10 newtons + 10 newtons)
Net force = 20 newtons
Thus, the net force of their efforts is 20 newtons.
If the refractive index of some substance is 1.33, then
the speed of light in that substance is
(speed of light in vacuum) / (1.33) =
(299,792,458 m/s) / (1.33) = <em>225,407,863 m/s</em>
Answer:
Acceleration=
Speed=0.67 m/s
Explanation:
We are given that
Horizontal force=F=20 N
Mass of box=m=40 kg
We know that
Acceleration=
Using the formula
Acceleration of box=
The acceleration of the box=
Initial velocity=u=0
Force=F=30 N
Distance=s=0.3 m


Substitute the values



Hence, the speed of the box after it has been pulled a distance of 0.3 m=0.67 m/s
It would need to be over 20 because if the load of the Pulley E is 20 and the effort is 20, then they will be equal and the Pulley would not move, so your answer is at least 20
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.
