Round to three significant figures and enter your answers in scientific notation. Find the frequency and wavelength of a 53−MeV gamma-ray photon. f=___x10___Hz

Need help finding % difference last question on page. I kind of have an idea of how to set up but my answer isn’t making sense.

Problem 1 Use the properties of Gamma functions to solve these expressions by hand. a program such as a T[ ] × [4] b C 3 — 92 xr 5 9 T[-2] × [2] Г xr 4 4

Three students, Tom, Sally and Kevin, did an experiment where the accepted size of nano-particles of calcium-tin-oxide is 105.0 nm. Their findings are given in the table below. Whose measurement is most precise, and whose is most accurate? Note that measurement is done in nanometers (nm). Kevin (nm) Sally (nm) 107.0 Trial No. Tom (nm) 1. 103.7 107.7 2. 105.6 101.1 107.5 3. 106.9 105.4 107.9 Mean 105.4 104.5 107.7 None of the given options Tom's measurement is most precise, and Kelly's measurement is most accurate. Sally's measurement is most precise, and Kelly's measurement is most accurate. Kevin's measurement is most precise, and Tom's measurement is most accurate

Please explain with every step how to solve this equation. I have seen it worked out before so I know the math and the answer but I really need it explained well so that I understand it.    Find the frequency and wavelength of a 50 Mev Gamma ray photon

This is the lab and It is not the writing assignment. please help me with this.  I appreciate it. Thank you! please don't reject it!!

C. leas t del Niu 3. Three students make measurements (in m) of the length of a rod using a meter stick. Each student's measurements are tabulated in the table below. Using your calculator in statistic mode calculate the mean L, standard deviation S and uncertainty u of the measurements. Student L1 L3 L2 1.4711 L4 1.4715 SD u Student 1 1.4717 1.4722 1,4716 t.4754 1.4710 1.4753 1.4759 1.4756 1.4749 Student 2 Student 3 1.4719 1.4723 1.4705 1.4719 Note that the actual length of the rod is determined by a laser measurement technique to be 1.4715 m (this should be considered the standard value). a) State how one determines the accuracy of a measurement. Apply your idea to the measurements of the three students above and state which student has the most accurate measurement.

y1 = sin(pi(x) - 2(pi)(t))......y2 = sin(pi(x)/2 + 2(pi)(t))

A laboratory that uses radioactive substances received a shipment of 122 g of bismuth-210. Only 6.64 g of the bismuth-210 remained 21.0 days later. Determine the half-life of bismuth-210 algebraically using logarithms, to the nearest tenth of a day. The half-life equation is A = A. where A represents the amount of the substance remaining, Ao represents the initial amount of the substance, t represents the time, and h represents the time at which only half of the substance remains.
