Calcium and vitamin D are essential to building strong, dense bones when you’re young and to keeping them strong and healthy as you age. The information included here will help you learn all about calcium and vitamin D – the two most important nutrients for bone health.
What is Calcium and What Does it Do?
Cheese, milk, fish, almonds, and other bone-healthy foods
A calcium-rich diet (including dairy, nuts, leafy greens and fish) helps to build and protect your bones.
Calcium is a mineral that is necessary for life. In addition to building bones and keeping them healthy, calcium enables our blood to clot, our muscles to contract, and our heart to beat. About 99% of the calcium in our bodies is in our bones and teeth.
Every day, we lose calcium through our skin, nails, hair, sweat, urine and feces. Our bodies cannot produce its own calcium. That’s why it’s important to get enough calcium from the food we eat. When we don’t get the calcium our body needs, it is taken from our bones. This is fine once in a while, but if it happens too often, bones get weak and easier to break.
Too many Americans fall short of getting the amount of calcium they need every day and that can lead to bone loss, low bone density and even broken bones.
How Much Calcium Do You Need?
Answer:
The value of the equilibrium constant at this temperature is 3.42.
Explanation:
Partial pressure of the sulfur dioxide =
Partial pressure of the oxygen gas =
Partial pressure of the sulfur trioxide =
The expression of an equilibrium constant is given by :
The value of the equilibrium constant at this temperature is 3.42.
Sea breeze, land breeze, mountain breeze, and valley breeze.

Explanation:
It is known that relation between heat energy and temperature change is as follows.
Q =
where, q = heat energy
m = mass of the solution or solvent
= change in temperature
Hence, putting the given values into the above formula as follows.
Q =
=
= 34650 J
Now, calculate the energy of photons at wavelength 3.02 mm as follows.
E =
where, h = planks constant =
c = velocity of light = m/s
= wavelength = 3.02 mm = m (as 1 m = 1000 mm)
Therefore, putting the given values into the above formula as follows.
E =
=
= J
Now, the number of photons required of energy J/photon for the total energy of 34650 J as follows.
n =
=
= photons
or, = photons
Thus, we can conclude that the minimum number of photons present are .
