Why are oxygen and hydrogen two of the most abundant elements in living things

Physics
1 answer:
katen-ka-za [31]3 years ago
6 0

Answer:

Oxygen and Hydrogen are the most abundant elements found in living beings because of their combination to form water together that builds the 70% of the living body, oxygen being used in respiration and Hydrogen being used to form other compounds as it has the simplest structure and least requirements to bond with other elements.

Explanation:

To build something, it's is important to start with the simplest formation and proceed to the complex ones. Same case applies on living beings. With the creation of all living bodies, two of the most abundant elements Hydrogen and Oxygen tends to volunteer in the formation of living bodies. Their simplest structure and least requirements to bond easily with other elements also make them suitable for the creation of living bodies.

Hydrogen consisting of only one proton and one neutron, easily collaborates with other elements and forms the complex compounds. Whereas, oxygen being processed under the respiration system, helps in developing important organs and compounds. And, most importantly not to forget point is that they both combine to make the significant compound of the living body i.e water. However, Carbon, Nitrogen and other traces are also present in the living beings but these two serve as the saviors of the war.

Recessed incandescent luminaires not marked type ic and those marked for installing directly in ___________ must not have insula
slavikrds [6]

Answer:

Recessed incandescent luminaires not marked type ic and those marked for installing directly in insulated ceilings must not have insulation over the top of the luminaire.

Explanation:

Depending on how they interact with insulation, lighting fixtures are rated at various levels. Non-IC rated lighting fixtures can accommodate higher wattage bulbs, but they also pose the greatest fire risk when used with the incorrect insulation.

In locations with insulation, light fixtures that are not IC rated may be installed. But there is a condition. The distance between the fixture and any insulation should be 3 inches. But the 3 inch gap in the insulation would negate the goal of insulation by producing a lot of uninsulated space, so this defies logic. Building a box-style cover to cover the fixture on the attic side is one option to fix this. Drywall or foil-faced foam insulation can be used to create this box. After the cover is put in place, insulation can be added for maximum effectiveness.

A truck covers 47.0 m in 8.60 s while smoothly slowing down to final speed of 2.30 m/s. (a) Find its original speed.
Kruka [31]

Explanation:

Given that,

Distance, s = 47 m

Time taken, t = 8.6 s

Final speed of the truck, v = 2.3 m/s

Let u is the initial speed of the truck and a is its acceleration such that :

a=\dfrac{v-u}{t}.............(1)

Now, the second equation of motion is :

s=ut+\dfrac{1}{2}at^2

Put the value of a in above equation as :

s=ut+\dfrac{1}{2}\times \dfrac{v-u}{t}\times t^2

s=\dfrac{t(u+v)}{2}

u=\dfrac{2s}{t}-v

u=\dfrac{2\times 47}{8.6}-2.3

u = 8.63 m/s

So, the original speed of the truck is 8.63 m/s. Hence, this is the required solution.

An electric generator converts kinetic energy into which kind of energy?
dem82 [27]

Answer:

Electrical Energy

Explanation:

An electric generator is a device that changes kinetic energy to electrical energy through electromagnetic induction. Electromagnetic induction is the process of generating electric current with a magnetic field. ... Because the coil is rotating in a magnetic field, electric current is generated in the wire.
