When the core temperature rises, stars start burning helium to carbon. Hydrogen and helium are fused in a shell surrounding the core, raising the temperature.
The most prevalent method of generating energy in the cosmos is hydrogen fusion. The gravitational force is utilised to fuse hydrogen at the centres of our Sun and other stars, where it has a density more than 70 times greater than that of steel. Thus, all of the heat and light on earth comes from fusion. Helium is a chemical element with the atomic number 2 and the symbol He. The first member of the noble gas group in the periodic table, it is a colourless, odourless, tasteless, inert, monatomic gas that is not harmful.

Force the glove exerts on the ball
Explanation:
The reaction to this force is the force the glove exerts on the ball.
According to Newton's third ;aw of motion "Action and reaction forces are equal and opposite in direction".
- The action force is the impact of the ball against the players glove.
- The reactive force is the force the glove exerts on the ball.
This reactive force is directed in the opposite direction and it is the reason why the motion of the incoming ball is halted.

Answer:
i think human is more complex.human is multicellular organisms as yeast is unicellular organisms. more cell and tissue is found in human but less in yeast.human have organs like heart,stomach, brain ,e.t.c. but yeast do not have.
Answer:
Explanation:
a ) The volume of blood flowing per second throughout the vessel is constant .
a₁ v₁ = a₂ v₂
a₁ and a₂ are cross sectional area at two places of vessel and v₁ and v₂ are velocity of blood at these places .
2A x v₁ = A x .40
v₁ = .20 m /s
b )
Let normal pressure be P₁ when cross sectional area is 2A and at cross sectional area A , pressure is P₂
Applying Bernoulli's theorem
P₁ + 1/2 ρv₁² = P₂ + 1/2 ρv₂²
P₁ - P₂ = 1/2 ρ(v₂² - v₁² )
= .5 x 1060 ( .4² - .2² )
= 63.6 Pa .
The number of electrons is 
Explanation:
The total net charge on a negatively-charged object is given by
where:
N is the number of excess electrons
is the charge of a single electron
In this problem, we have
is the overall charge of the object
is the charge of one electron
Solving the equation for N, we find:
