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:
14.56 N
Explanation:
According to Newton's second law of motion,
The force acting on a body is equal to the product of its mass and acceleration acting on it.
Weight of a body on a planet is equal to the force due to gravity of the planet. So, weight is the product of mass of body and acceleration due to gravity of the planet.
Here, acceleration due to gravity on planet A is m/s² and mass of an object on it is kg.
So, weight of an object, , on planet A is given as,

Answer:
centripetal acceleration of the ball is 6.9 m/s/s
tangential speed of the ball is 2.2 m/s
Explanation:
As we know that ball complete 5 rotations in 10 seconds
so frequency of rotation of ball is given as
now we know that angular frequency is given as
Now centripetal acceleration is given as
now the velocity of the ball at this angular frequency is given as
