Answer:

Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

HELP ASAP: <br><br> how many trials did it take for half of the virtualium atoms to decay?
Len [333]

Answer:

<h3><u><em>Carbon-14 has a half-life of 5,730 years. Taking one atom of 14C, this will either have decayed after 5,730 years, or it will not. But if this experiment is repeated again and again, it will be seen that the atom decays within the half life 50% of the time.</em></u></h3>

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo
ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L

Why would a fish with faulty valves in its conus arteriosus probably suffer from a lack of energy?
d1i1m1o1n [39]

A faulty conus arteriosus  would compromise on an effective gaseous exchange that keeps the blood of the fish oxygenated for respiration of tissues. The conus arteriosus is one of two accessory chambers found in most fish with two-chambered hearts. The primary function of the conus arteriosus is to prevent the backflow of blood and keep a steady flow of blood into the ventral aorta and the gills.
