High-Energy Cancer Treatment. Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1012 W) pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk in 3 mm diameter, with the pulse lasting for 7 ns with an average power of 7.4 x10¹2 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. How much energy is given to the cell during this pulse?

Orbital plane change: A satellite is launched due east from the Kennedy Space Center (latitude 28.6º). Following orbit insertion and a circularizing second burn with no plane change, the satellite is in a circular orbit at an altitude of 540 km. Its final destination is a circular orbit at 15,000 km with an inclination of 0 degrees. a. Using two Hohmann transfers, what total Δv is required to move the satellite from the initial orbit to the higher circular at the same inclination? Include a sketch showing the initial orbit, the transfer orbit and the final orbit. Include the location(s) of the burn(s). b. Calculate the Δv required to change the orbital inclination from its initial value to zero degrees in both the initial circular orbit and the higher circular orbit. Where would you want to make the change to the orbital inclination?

Consider an electron orbiting around a proton with an orbital radius of R=8.48⋅10−10R=8.48⋅10-10 m. What is the orbital frequency of the electron motion? Use me=9.11×10−31me=9.11×10-31 kg, e=1.6×10−19e=1.6×10-19 C, and k=9×109k=9×109 Nm2/C2. The frequency, f0 = Units . By how much would this frequency increase (assume the same orbital radius) if an external magnetic field of B = 0.5 T is applied to the system along the the electron axis of rotation?

Particle track detectors are used to measure the speed of particles if the lifetime of the particle is known. Particle X has a lifetime of 256.2 ps. These particles are created in an experiment inside the detector by a given reaction. The particles leave 21.6 cm long tracks on average before they decay into other particles not observable by the detector.What is the average speed of the particles in terms of the speed of light?
An electron and an antielectron (each has mass 9.11 x 10-31 kg), each traveling at 0.6c relative to the lab frame, collide head on and annihilate, resulting in the creation of two identical photons which travel away in opposite directions. What is the frequency of each photon?
been having some trouble with this problem: Michelson used rotating mirrors, similar to those shown below, to calculate the speed of light. Light is emitted from the light source, reflects from mirror surface X to the plane mirror, and then to the position of surface Z. By the time the light moves from the X to Z position, mirror surface X will have moved to the position of mirror surface Z. The light then continues to the observer. The distances from the light source and the observer to the rotating mirrors are negligible. The distance from the rotating mirrors to the plane mirror is 35.0 km.If the mirrors are rotating at 480 rev/s, the speed of light calculated from the given information is
21. Shining a Laser. You are in the magic school bus alone. For some reason, you decide to shine a laser straight up. The bus is at a height h = 3.50 m, excluding the wheels, and is travelling at a speed v = 0.800c. Now, your crush is on a car at rest, watching as the bus goes right past. (a) What is the time it takes for the light in your perspective to bounce from the laser to the top of the bus, then to the floor, and back to the laser? (b) Do this same calculation, but for your crush's perspective. Hint: Light travels at the same speed from any perspective. (c) What is the ratio of the time from your crush's view and that of your view?
