Question: In a supermarket, you place a 22.3 N (around 5 lb) bag of oranges on a scale, and the scale starts to oscillate at 2.7 Hz.
A- What is the force constant (spring constant) of the spring of the scale?
Please clarify the equations and steps are used to get the answer, also where the numbers are coming from. Thanks!
Estimate how many molecules of air are in each 1.8 L breath you take that were also in the last breath Einstein took (assumed to be the same volume). (Hint: Assume the atmosphere is about 12 km high and of constant density. Take the temperature of th..
After being accelerated to a speed of 1.26×105 m/s, the particle enters a uniform magnetic field of strength 2.00 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen). The results of this experiment allow one..
