2- Find the period of the subsequent simple harmonic motion.
A C1=25 uF capacitor is charged to 4.0kV and then removed from the battery and connected to uncharged C2=45uF capacitor. which capacitor stores more energy and why
During 9.93 seconds a motorcyclist changes his velocity from v1,x = -37.3 m/s and v1,y = 14.1 m/s to v2,x =-21.9 m/s and v2,y = 29.3 m/s. Find the components of the motorcycle's average acceleration during this process, aav,x and aav,y.
In an X-ray tube electrons strike a tungsten target (W or "wolfram") after being accelerated through a potential difference V0. Estimate the minimum value of V0 required to observe the Kalpha peak.
Two waves have the exact same frequency, wavelength, and amplitude. They are both travelling in the +x direction, What is the phase difference between the two waves.
