The uncertainty on the momentum is
Explanation:
We can solve the problem by using the uncertainty principle, which states that:
where
is the uncertainty on the position
is the uncertainty on the momentum
is the Planck constant
For the nucleus in this problem, the uncertainty on the position is equal to the size of the nucleus, therefore
Therefore we can substitute into the equation and solve for to find the uncertainty on the momentum:

Answer:
first you have to organize the data. a=acceleration t=time v0=inicial velocity vf=final velocity
a=2.92m/s2
t=5.1s
vf=?
v0=0
now the formula you have to use is: vf=vi+a*t (final velocity equals to inicial velocity plus acceleration times time)

46.58m/s²
26.43kg
Explanation:
Given parameters:
Force = 67N force = 185N
Mass = 1.43kg acceleration = 7m/s²
Unknown:
Acceleration = ?
mass of the object = ?
Solution:
According to newton's second law of motion "the net force on a body is a product of its mass and acceleration".
Force = mass x acceleration;
For the first problem;
the unknown is the acceleration;
Acceleration = = = 46.58m/s²
Using the same law, to find the mass of the second object, we make it the subject of the formula;
mass =
mass = = 26.43kg

I don't know what " hm/h " means as a unit of speed. But if the bright red object is traveling in a straight line at a constant speed, then its acceleration is zero, and that means that the net force acting on it is zero. The same would be true of a car of any other color traveling with the same velocity.
That's true.
I have a hunch that there definitely IS a change of phase at every reflection.
