Answer:
42 kg.m/s if the two are moving in the same direction
Explanation:
momentum formula: p=mv
22kg.m/s+20kg.m/s= p
42kg.m/s=p
the momentum of both objects=42 kg.m/s

Answer:
A. Trapping energy from the sun in the earth's atmosphere
Explanation:
The gases in the atmosphere have detrimental role in the global climate. The greenhouse gases, such as the carbon dioxide and methane have the ability to trap heat into the atmosphere. the heat that is trapped is the one that is bounced back from the earth's surface and back into the space, but these gases manage to retain big portion of it. As more and more heat is trapped, the atmosphere gradually becomes warmer, resulting in global climate changes, and overall a warmer earth, thus having the effect of the greenhouse on the planet.
Answer:
The correct answer is - C. protein - Millons' test - red precipitate is formed.
Explanation:
The iodine test is the test that is used for the identification or presence of the starch in a food sample, in this test if starch present in the food then the solution of iodine and KI will turn to deep blue color. Therefore the given result is incorrect
The benedict test for confirming if glucose present in the sample, it is a mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate which starts as aqua blue in color but after adding sample and gradually heating it turns from yellow to orange as per the concentration of the glucose. Thus, it is incorrect.
The emulsion test also produces the milky precipitate or emulsion in presence of fat or lipid in the sample. so, it is incorrect.
Millon's test for protein is the test that results in the red solution or red precipitate in the presence of the protein in the sample.
ATP stands for andensoine triphosphate
It is the energy currency of the cell because it is used to store energy in the body
