Use the heisenberg uncertainty principle to calculate the uncertainity in meters in the position of 0.68g and traveling at a velocity of 0.85 m/s. assume the uncertainity in meters in the position of a helium atom if the uncertaunty in the velocity is 0.1 m/s

7.7439×10⁻³¹ m

Explanation:

The expression for Heisenberg uncertainty principle is:

Where m is the mass of the microscopic particle

h is the Planks constant

Δx is the uncertainty in the position

Δv is the uncertainty in the velocity

Given:

mass = 0.68 g = 0.68×10⁻³ kg

Δv = 0.1 m/s

Δx= ?

Applying the above formula as:

Δx = 7.7439×10⁻³¹ m

the answer is true. hope it .

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
