How would you use the index of refraction of salt water to find the concentration of a salt solution?

As the salt solution increases its salinity, its refractive index also increases, with decreasing temperature. Through this relationship, the refractive index of salt solution at a constant temperature can be used to determine the concentration of the said solution.

Scurvy and rickets are micronutrient deficiency diseases due to a lack of certain vitamins or minerals in the diet. Scurvy is caused by vitamin C deficiency and rickets by vitamin D.

<h3>What are proteins and carbohydrates?</h3>

  • Proteins and carbohydrates are the macronutrient in the body and are sources of energy. Proteins are made of amino acids linked together by the peptide bond and carbohydrates are made of carbon, oxygen, and hydrogen.

  • Breathing is a biological process that involves exhalation and inhalation, while respiration is a chemical process that occurs in body cells and tissues.

  • The cerebrum and cerebellum are the parts of the brain involved with different functions. The cerebrum of the forebrain is involved with mental, motor, and sensory functions, while the cerebellum is involved with posture, balance, and coordination.

  • The infectious disease gets transmitted to another person by viruses, bacteria, fungi, etc., and non-infectious are non-communicable disease that includes age, deficiency, etc.

When Woods hits a 0.04593 kg golf ball, the golf ball is usually traveling around 281 kilometers per hour. What average force do
Semenov [28]

Answer:

128.9 N

Explanation:

The force exerted on the golf ball is equal to the rate of change of momentum of the ball, so we can write:

F=\frac{\Delta p}{\Delta t}

where

F is the force

\Delta p is the change in momentum

\Delta t=0.030 s is the time interval

The change in momentum can be written as

\Delta p = m(v-u)

where

m = 0.04593 kg is the mass of the ball

u = 0 is the initial velocity of the ball

v=281 km/h =78.1 m/s is the final velocity of the ball

Substituting into the original equation, we find the force exerted on the golf ball:

F=\frac{m(v-u)}{\Delta t}=\frac{(0.04593)(78.1-0)}{0.030}=128.9 N
