A compound microscope has a barrel of length 155 mm. The focal lengths of the objective and the eyepiece are 4.21 mm and 24.5 mm, respectively. Determine the magnitude of the total angular magnification M of the microscope for a person whose near point is 25.0 cm away. M = Is the image seen in the microscope upright or inverted? ◇ inverted O upright

Modern PhysicsDerive the equation above to form the answer highlighted. Show the solution. Derive the equation ∆t = 2/cv √(∆tnot/2)² + (V∆t/2)² and it should come up with that highlighted answer below. So it means that you need to show the process of the solution on how that equation comes up with that highlighted answer.

Asap please......

This was wrong. Can you solve this again with these numbers? What is the root mean square velocity, vrms, for Hydrogen molecules (H2) at 20oC? Hint: How many amu does an H2 molecule contain. 1 amu = 1.67 x 10-27 kg Boltzman's Constant, k = 1.38 x 10-23 J/K Give your answer in m/s to 4 significant figures (NO DECIMALS)

Please don't provide handwritten solution .....
