A car speedometer has a 4% uncertainty. What is the range of possible speeds (in km/h) when it reads 60 km/h?
(a) A car speedometer has a 6% uncertainty. What is the range of possible speeds when it reads 80 km/h? km/h (lowest) km/h (highest) (b) Convert this to miles per hour. mi/h (lowest) mi/h (highest)
5. What is the minimum uncertainty in the position of an electron traveling at 8.4 x 104 + 0.6 x 104 km/s ? Notes: 1 Joule (J) = 1 kg•m²/s2 melectron = 9.11 ~ 10 kg
Understand the Heisenberg Uncertainty Principle Question If the uncertainty associated with the position of an electron is 3.3 x 10-5 m, what is the uncertainty associated with its momentum? Use h = 1.055 x 10-34 kg m- Select the correct answer below: O 1.6 x 10-24 km O 5.2 x 10-24 km O 3.9 x 10-25 kg O 6.1 x 10-25 kg

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...
QUESTION 4 Two planes A and Bare flying at the same altitude. If their velocities are = 500 km/h and 1700 km/h such that the angle between their straight-line courses is 8 = 60°, determine the velocity of plane B with respect to plane A. - 500 km/h - 700 km/h B The magnitude of the velocity of B with respect to A in km/h is QUESTION 5 The conveyor belt is moving downward at 4 m/s. If the ms...
A. What is the percent uncertainty in the measurement 100.8 +- 0.50 cm B. What are the estimated and percent uncertainties in the measurement 5.28 C. estimate how long it would take one person to mow a lawn (20m long and 10m wide) using an ordinary mower. Assume that the mower moves with a 1 km/h speed, and has a 0.5m width D. A cart starts from rest and accelerates at 5.0 m/s^2 for 5.0s, then maintain that velocity for...
