Nancy and Hiyang are training for a race. They entered some of their training notes in a chart. A 3-column table with 5 rows. The first column labeled day has entries Monday, Tuesday, Wednesday, Thursday, Friday. The second column labeled Nancy's distance run has entries 2, 3, 3, 4, 5. The third column labeled Hiyang's distance run has entries 5, 5, 7, 8, 10.
Which information should be added to the chart in order find out who ran a greater distance?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
