An elevator w m = 4850 has max acceleration of 0.068g. What are max and min forces? I know F= m (a + g) so for acceleration would i multiply 0.068 x 9.8 (for g)? And then do I add the 0.068g and g (9.8) or multiply? My teacher got: F= (4850kg)(0.9320)(9.8) = 4.43 x 10^4 and i do not know where he got 0.9320 and i thought i would add (a +g) like the formula states. Please explain so i can understand. Thanks!

A particle (m = 2.7 × 10^-28 kg) starting from rest, experiences an acceleration of 2.4 × 10^7 m/s2 for 5.0 s. What is its de Broglie wavelength λ at the end of this period? Please help, I understand that v=at so you need to do 2.4 multiplied 5 and I got 12. Meaning v=12x10^7 Then I did h/mv which is (6.626x10-34)/(2.7x10^-28*12x10^7) and I finally got 2.045x10^-14 but this is still wrong and I don't understand why.

Figure shows a heavy cart, of mass m, which rolls down along the top surface of ramp of mass M. Top surface of ramp is inclined at angle Θ relative to the bottom surface of the ramp which lies on the horizontal floor. All friction forces are negligible. What is the acceleration of the ramp relative to the floor? (this question has been asked previously but i couldn't understand its solution so it would be great if someone could solve,...

ABG problem. Patient has respirations of 22 breaths/min, is in respiratory alkalosis and is hypoxic. What interventions do you use to fix this problem? The answer is decrease tidal volume and decrease respirations. For some reason I can't wrap my mind around this. If the patient is hypoxic why would we want to lower tidal volume? and increasing respirations helps us to blow off CO2 and gain more O2, so why would we decrease it? this is what I know...
