Answer:
Explanation:
= Uncertainty in position = 1.9 m
= Uncertainty in momentum
h = Planck's constant = 
m = Mass of object
From Heisenberg's uncertainty principle we know
The minimum uncertainty in the momentum of the object is
Golf ball minimum uncertainty in the momentum of the object
Uncertainty in velocity is given by
The minimum uncertainty in the object's velocity is
Electron
The minimum uncertainty in the object's velocity is .
Answer:
Explanation:
Can you please place the square roots in a proper manner so I may assist you?
Average speed = (distance traveled) / (time to cover the distance)
= (35 yards) / (3.8 seconds)
= 9.21 yards per second
Not so fast.
I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.
If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.
If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.
