According to the information given, the Heisenberg uncertainty principle would be given by the relationship
Here,
h = Planck's constant
= Uncertainty in velocity of object
= Uncertainty in position of object
m = Mass of object
Rearranging to find the position
Replacing with our values we have,
Therefore the uncertainty in position of electron is 
Answer:
Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.
The formulas that relate to this are given below:
P1 = P2 (since the pressures are equal throughout).
P2 is the pressure transmitted in the hydraulic system
N.B : P= Force/ Area
Therefore we have
F1/A1 = P2
F1= the force exerted by the driver = 100N
P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm
Answer:
147.15 Joules.
Explanation:
A 3 kilogram mass at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s2 * 5m = 147.15 J.
V^2 = 2a S
V = square root ( 2 x 0.5 . 4)
V = 2 m/s
Answer is B
Answer:
minimum horizontal force required to start the block motion is F = 0.41 mg
Explanation:
As we know that box is placed on the horizontal floor
so here the normal force on the box is counter balanced by the weight of the box
so we will have
now in order to displace the box from its position we need to apply the external force which will just exceed the limiting static friction force
So here we will have
here we know that
so minimum horizontal force required to start the block motion is F = 0.41 mg
