The speed of the electron in the water.

Question

Scientists are working on a new technique to kill cancer cells by zapping them with ultrahigh-energy (in the range of 1.00×1012 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 5.00 μm in diameter, with the pulse lasting for 4.00 ns with an average power of 2.00×1012 W. We shall assume that the energy is spread uniformly over the faces of 100 cells for each pulse. I 1.00×1021 W/m² Submit Previous Answers Part C Correct What is the maximum value of the electric field in the pulse? ΜΕ ΑΣΦ Emax Submit Request Answer Part D ?

A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this "solar sail." Suppose a sail of area A = 6.40 ✕ 105 m2 and mass m = 4,900 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1,370 W/m2. A) If the solar sail were initially in Earth orbit at an altitude of 360 km, show that a sail of this mass density could not escape Earth's gravitational pull regardless of size. (Calculate the magnitude of the gravitational field in m/s2.) B) What would the mass density (in kg/m2) of the solar sail have to be for the solar sail to attain the same initial acceleration of 1193 µm/s2.

hw 2 Laser beams are sometimes used to burn away cancerous tissue. What is the intensity, in watts per square meter, of a laser beam that is 90.0% absorbed by a 2.1-mm diameter spot of cancerous tissue and must deposit 515 J of energy to it in a time period of 4.05 s?
