Two equal forces F have resultant of 1.5F .Find the angle between the forces​
Grace [21]

Answer:

Angle between the forces​ = 82.82 degrees

Explanation:

The resultant force value = 1.5  times of Force F

|R| = |F1| = |F2| =|F|

Where R is the resultant force

R^2 = A^2 + B^2 + 2AB cos X\\(1.5F)^2 = F^2 + F^2 + 2F^2 cos X\\2.25F^2 = 2F^2 + 2F^2 cos X\\

Cos X is the angle between the two forces.

On further simplifying the equation we get

2.25F^2 = 2F^2(1 + cos X)

(1 + cos X) = \frac{2.25F^2}{2F^2} \\(1 + cos X) = \frac{2.25}{2} \\(1 + cos X) = 1.125\\cos X = 1.125 - 1\\Cos X = 0.125\\X  = Cos^{-1}0.125\\

X = 82.82 degrees

Angle between the forces​ = 82.82 degrees

Catalase is an enzyme that is found in all living tissues. Cells need catalase in order to function properly. Which of the follo
ryzh [129]

Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.

Explanation:

Studies in biology have demonstrated that:

- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)

- All living tissues has a stable physiological temperature of 37°c

- All living tissues contain enzymes such as Catalase

Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.

Which of the following is nicknamed the “powerhouse “ of the cell ?
lakkis [162]

Mitocondria is nicknamed the powerhouse of the cell,  These structures are nicknamed the powerhouse of the cell because they work to convert energy into forms that the cell is able to use. Mitochondria are semi-autonomous cells, which means that they only rely partly on the cell for division and growth.
