The uncertainty in an electron's position is 0.005 nm. What is the minimum uncertainty delta p in its momentum? Express your answer using two significant figures. delta p_min kg middot m/s What is the kinetic energy of an electron whose momentum is equal to this uncertainty (delta p = p)? Express your answer using two significant figures. K = 381.6 eV
The uncertainty in a proton's position is 0.010 nm. What is the minimum uncertainty Δp in its momentum?Express your answer using two significant figures. Δpmin =_______kg⋅m/s Part B What is the kinetic energy of a proton whose momentum is equal to this uncertainty (Δp=p)? Express your answer using two significant figures. K=________ meV please!!
What is the minimum uncertainty in position, in nm, of an electron whose velocity is known to be between 2.94×105 m/s and 3.88×105 m/s ?
What is the minimum uncertainty in position, in nm, of an electron whose velocity is known to be between 3.34×105 m/s and 3.66×105 m/s ?
What is the minimum uncertainty in position, in nm, of an electron whose velocity is known to be between 2.94×105 m/s and 3.88×105 m/s ? You may have used the reduced Planck constant in the uncertainty principle. Note that in statements of the uncertainty principle the right side could have different meanings (just h or it could contain various factors of PI), but we have h/2 *******THE ANSWER IS NOT .615, .616, .617******** Please Help
Part A Part complete The x coordinate of an electron is measured with an uncertainty of 0.200 mm . What is vx, the x component of the electron's velocity, if the minimum percentage uncertainty in a simultaneous measurement of vx is 1.00 % ? Use the following expression for the uncertainty principle: ΔxΔpx≥h2, where Δx is the uncertainty in the x coordinate of a particle, Δpx is the particle's uncertainty in the x component of momentum, and h is Planck's...

Part A With what minimum speed must you toss a 200 g ball straight up to hit the 15-m-high roof of the gymnasium if you release the ball 1.5 m above the ground? Solve this problem using energy. Express your answer using two significant figures. (answer v_min = m/s) Part B With what speed does the ball hit the ground? Express your answer using two significant figures. (answer v = m/s)
l Review Part A In the Bohr model, as it is known today, the electron is imagined to move in a circular orbit about a stationary proton. The force responsible for the electron's circular motion is the electric force of attraction between the electron and the proton. If the speed of the electron were 4.4x105 m/s, what would be the corresponding orbital radius? Express your answer using two significant figures.
