An unstable particle with a mass equal to 3.34 x10-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.983c and -0.863c, respectively. Discover the masses of the fragments. (Hint: Conserve both momentum and mass-energy.)
A. The rate of hydrogen fusion (proton-proton chain) near 10^7 K increases with temperature as T^5. If you raise the temperature of the hydrogen-burning core by 10 percent, how much does the hydrogen fusion energy increase?
Old naval ships fired 13 kg cannon balls from a 210 kg cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship.
An electron is accelerated from rest by a potential difference of350V. It then enters a uniform magnetic field of magnitude 200mTwith its velocity perpendicular to the field.
A transformer consisting of two coils wrapped around an iron core is connected to a generator and a resistor, What is the peak emf of the generator?
A constant force of 46.3 N, directed at 28.7o from horizontal, pulls a mass of 14.7 kg horizontally a distance of 3.09 m
Consider a series LRC circuit with R=201 ?, L=0.34 H and C=1 µF. The current is 10 mA amplitude at 2 kHz. Remember ? = 2pf, where f is the frequency in cycles per second or Hz. Find the voltage amplitude VL on the coil. Express the answer with two..
