Sarah starts at x1 = 6 miles from the origin, walks along the x-axis to x2 = 10 mile, takes a rest, and finally walks to x3 = 2 miles.
1. What is her displacement?
2. What is her distance?(how long did she walk).
Electrons in an x-ray machine are accelerated from restthrough a potential difference of 50 000V. what is the kinetic energy of each of these electrons in eV
The velocity selector in the figure is designed to allow charged particles with a speed of 4700 m/s to pass through undeflected. Find the magnitude of the required electric field
Suppose you decide to take a trip in your car today. You start out and drive 32 miles in 20 minutes, What is your average speed for the entire trip including when you were parked
The electric field of a capacitor remains unchanged, if the plates change their separation, but the charges remain the same. Show with equations the new energy of the capacitor relative to the initial energy, if the separation is doubled.
A 0.150-kg frame, when suspended from a coil spring, stretches the spring 0.070m . A 0.200-kg lump of putty is dropped from rest onto the frame from a height of 30.0cm.Find the maximum distance the frame moves downward from its initial position.
Four identical metallic objects carry the following charges: +5.8 µC, +8.2 µC, -6.2 µC, and -2.8 µC. What is the final charge on each object
