In quantum mechanics,

the basic wave function has no physical meaning or significance. However,

represents the probability distribution of particle in a given space.
Probability

So when you will put a position and a time in

function, it will give you the probability of finding the particle at that particular position and at the given time.
Answer:
B. 2 Hours
Explanation:
If you are going 45 miles per hour, you will travel 45 miles in 1 hour. It will take you 2 hours to travel 90 miles at a speed of 45 miles per hour.
Answer:
It states a fact about how nature works.
It often changes over time with new experiments and technology.
Answer:
you just have to draw a line from the eye reflecting from the mirror to the object shown.
Explanation:
Dont come at me if its wrong. I think thats what their asking of you.
ThIs is the same type of problem
find out the time value
3 = 1/2*a*T^2
6/10 = t^2
t = 0.77 seconds
and the distance is given 5 m
thus speed ,= distance/time
speed = 5/0.77
= 6.45 m/s
