Complete the statements about the law of conservation of momentum.

Biology
1 answer:
vitfil [10]3 years ago
8 0

Answer:

The law of conservation of momentum states that the total momentum of interacting objects does not change.

This means the total momentum before a collision or explosion is equal to the total momentum after a collision or explosion.

Explanation:

The law of conservation of momentum is derived from Newton's third law of motion which states that action and reaction are equal and opposite.

The law of conservation of momentum can be stated as follows.

For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

g Indium has two naturally occurring isotopes: 113In with an atomic weight of 112.904 amu, and 115In with an atomic weight of 11
aleksandrvk [35]

Answer:

Fraction-of-occurrences of 115In isotope = 0.957

Explanation:

As we know  weight of 113 In  isotope is equal to the sum of product of fraction-of-occurrences of two constituents isotopes and their atomic weight

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115} ------(1)

As we know sum of fraction-of-occurrences of two constituents isotopes is equal to one.

f_{113} + f_{115} = 1\\f_{113} = 1- f_{115}---------(2)

Substituting the given values in equation 1, we get

^{115}In_w = f_{113}*A_{113} + f_{115}*A_{115}\\114.818 = (1 - f_{115}) * 112.904 + f_{115} * 114.904\\f_{115} = 0.957

Substituting this value in equation 2 we get -

f_{113} = 1- f_{115}\\f_{113} =  1- 0.957 \\f_{113} = 0.043

Cells import useful solids and fluids by ________________.
MAVERICK [17]

Answer:

The correct answer is option d, that is, endocytosis.

Explanation:

A procedure in which a component gains entry within the cell without getting passed through the cell membrane is termed as endocytosis. In this process, the cell captivates the substances from the external of the cell by engulfing and combining them with its plasma membrane.  

The process is further differentiated into three distinct kinds. These are phagocytosis, pinocytosis, and receptor-mediated endocytosis.

According to the results for Patient 1 shown above, which antigens were present in Patient 1’s blood? Check all (if any) that ap
soldier1979 [14.2K]

Answer:

A.

Explanation:

Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.
