Which elements are found in all living things? 30 POINTS!!
carbon, oxygen, potassium, calcium, nitrogen, sulfur
hydrogen, phosphorus, oxygen, calcium, nitrogen, sulfur
carbon, hydrogen, phosphorus, oxygen, nitrogen, sulfur
hydrogen, oxygen, potassium, calcium, nitrogen, sodium

The correct option is C

Oxygen

Carbon

Hydrogen

Nitrogen  

Sulfur

Phosphorus

Explanation:

Oxygen is considered to be the most abundant element to be found in the living cells. Usually, a living cell is made up of 65% oxygen.

Carbon is the element which forms the basis for life for all organisms which can be seen on the planet Earth.

Hydrogen combines with oxygen to form water which makes up 65 percent of the human body.

Nitrogen is an active constituent of molecules such as proteins which are of utter importance to an organism.

Phosphorus is present in the form of phospholipid layer which is an active constituent of the cell membranes.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
