Answer:
A
Explanation:
It is formed after the star has ended its star cycle into a supernova. The star collapsed into a neutron star that is smaller than the progenitor star but has inherited angular momentum. IT, therefore, spins faster emitting electromagnetic radiation that seems to pulsate.
The average speed :
1. 10.44 m/s
2. 10.42 m/s
3. 9.26 m/s
The distance 100 m have the greatest average speed

Given
Distance and time of runner
Required
Average speed
Solution
<em>
Average speed : total distance : total time
</em>
1. d = 100 m, t = 9.58 s
Average speed : 100 : 9.58 = 10.44 m/s
2. d=200 m, t=19.19 s
Average speed : 200 : 19.19 = 10.42 m/s
3. d=400 m, t = 43.18 s
Average speed : 400 : 43.18 = 9.26 m/s
The distance 100 m have the greatest average speed
Answer:
D.Lowering the temperature is the best option.
Explanation:
The value of equilibrium constants aren't changed with change in the pressure or concentrations of reactants and products in equilibrium. The only thing that changes the value of equilibrium constant is a change of temperature.
In the reaction below for example;
A + B <==>C+D
If you have moved the position of the equilibrium to the right (and so increased the amount of C and D), why hasn't the equilibrium constant increased?
Let's assume that the equilibrium constant mustn't change if you decrease the concentration of C - because equilibrium constants are constant at constant temperature. Why does the position of equilibrium move as it does?
If you decrease the concentration or pressure of C, the top of the Kc expression gets smaller. That would change the value of Kc. In order for that not to happen, the concentrations of C and D will have to increase again, and those of A and B must decrease. That happens until a new balance is reached when the value of the equilibrium constant expression reverts to what it was before.
Answer:
<h2>A star's life cycle is determined by its mass. The larger its mass, the shorter its life cycle. A star's mass is determined by the amount of matter that is available in its nebula, the giant cloud of gas and dust from which it was born. ... As the gas spins faster, it heats up and becomes as a protostar.</h2>
