Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.
Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.
Ek = 1/2 · m(bowling ball) · v²(bowling ball).
m is mass; v is speed of bowling ball.
The standard unit of kinetic energy is the joule.
Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .
<h3>What do you mean by the nuclear fusion ?</h3>
Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy.
The main advantage of nuclear fusion is it is safe source for the generation of electricity.
Characteristics of nuclear fusion -:
- The main characteristic of nuclear fusion is that it involves formation of a singular particle from two or more atoms.
- Unlike nuclear fission, nuclear fusion is common in nature- just hard to recreate.
- Nuclear fusion typically produces few radioactive particles .
- Fusion works by applying a great deal of pressure to overcome .
Hence ,Iron is the heaviest element produced in large stars by nuclear fusion near the end of their life cycle .

Answer:
At end point there will a transition from pink to colorless.
Explanation:
As the student put the vinegar in the titrator and NaOH in the beaker, it means that he has poured phenolphthalein in the NaOH solution.
The pH range of phenolphthalein is 8.3-10 (approx), it means it will show pink color in basic medium.
So on addition of phenolphthalein in NaOH the solution will become pink in color.
When we start pouring vinegar from titrator neutralization of NaOH will begin.
On complete neutralization , on addition of single drop of vinegar the solution will become acidic and there will be complete disappearance of pink color solution in the beaker.
Answer:
Explanation:
a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional ammonia will be produced .
b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.
c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³
d ) Substituting the given values in the equation ,
Keq = [ 6M ] ² / [ 3M] [ 4M]³
= 36 / 3 x 64 M⁻²
= 18.75 x 10⁻² M⁻² .
Answer:
A. 0.15 M NaOH, and
E. 0.15 M HNO3
Explanation:
A buffer solution contains a conjugate acid-base pair with both the acid and the base in reasonable concentrations.
NaOH and HNO3 is an acid base pair with relatively equal concentrations. So, they would most likely make a buffer solution.
