Students were in charge of presenting information they found about the various types of waves to their group. Carl told his group “this wave can be transverse, travel through solids, and has a high frequency”. Four different students responded with the questions shown. Which student asked a question that would allow students to determine if Carl is talking about an electromagnetic wave or a mechanical wave?

A.
Rebecca: “What is the amplitude of the wave?”

B.
Amy: “Is the wave carrying energy or matter?”

C.
Hanna: “Can the wave travel through something liquid too, like a milkshake?”

D.
Yvonne: “Can the wave also travel without a medium?”

Which of these is constant for all types of electromagnetic radiation in a vacuum? select one: a. wavelength b. frequency c. photon energy d. amplitude e. velocity

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0

You are doing a science experiment with a fahrenheit thermometer. your data must be in degrees celsius. if you measure a temperature of 125°f, what is this temperature in degrees celsius
