- A student determined that the density of a sample of tin is 8.00g/mL when the actual density of tin is 7.28g/mL. What was 91% 9.0% 9.9% 0.72%
- 4. Two atomic particles approach each other in a head-on collision. Each particle has a mass of 2.16X 10^-25 kg. The speed of each particle is 2.10times 10^8m/s when measured by an observer standing in the laboratory. (a) What is the speed of one particle as seen by the other particle? (b)Determine the relativistic momentum of one particle, as would be observed by the other.
- Try this practice question below! Monochromatic light from a helium-neon laser (lambda =632.8nm) shines at a right angle to a surface of a diffraction board (2 very small slits) that has a distance d=1/150500m between the slits. Find the angle at which you observe the first-order brightness (m=1)
