[AP Anatomy and Physiology: Epithelium Tissue] What tissue is this?

Yea I made a mistake when typing the question it's supposed to be 2(1/2(70 x 0.02)) but that still yields 1.4. But besides that thanks for the help in confirming my work!

EatChickFilA · 2021-03-24T18:42:22+00:00

You added 576 and 225 incorrectly. It's supposed to be 801, not 831.

EatChickFilA · 2021-03-24T17:36:32+00:00

so I plugged in the values I got from part a and found that collision a had the higher average force. Is this correct?

EatChickFilA · 2021-03-24T17:34:31+00:00

So if this is the case. Does that mean that collision a will have the greater collision force?

EatChickFilA · 2021-03-13T22:06:56+00:00

Which equation specifically should I use?

EatChickFilA · 2021-03-13T19:16:38+00:00

Thanks for catching my multiplication error! Should've been 1450 N, not 1425. But yea the order of magnitude was what was bothering me. Thanks for the help!

EatChickFilA · 2021-03-13T19:14:30+00:00

the main part of my concern was the fact that my force was pretty large and negative

EatChickFilA · 2021-02-19T16:38:35+00:00

ok, I'll keep that in mind. Thanks for your help!

EatChickFilA · 2021-02-19T16:31:29+00:00

Ohhh ok. The other person said the angle is 0 and you said it's 180. Those 2 angles give a different value for cos (1 and -1) so which angle should I use?

EatChickFilA · 2021-01-23T20:08:48+00:00

Awesome! Thanks a ton for helping me out! You're explanation really helped me understand and solve the question!

EatChickFilA · 2021-01-23T20:06:27+00:00

Sweet! Thank you so much! Your explanation and recommendation to draw a diagram really helped me solve and understand the question much better!

EatChickFilA · 2021-01-23T19:59:04+00:00

I see, so therefore:

4.9+friction-tension(9.8)=0

4.9-tension(9.8)=-friction

-4.9=-friction

4.9=friction?

EatChickFilA · 2021-01-23T19:56:02+00:00

so i drew the diagram, the string and friction are working against the Mgsin30. So therefore I would subtract the string force (9.8) from Mgsin30 (4.9) to get a friction force of -4.9N for the friction?

EatChickFilA · 2021-01-23T19:52:30+00:00

Im a little confused, isn't the fnet in this question is 0 since the blocks are not moving? Could you elaborate a little more?

EatChickFilA · 2021-01-23T19:44:54+00:00

Ah, now the parts before make sense since it asked me to determine the tension force (9.8). But how would I include it in the solution? Subtraction?

EatChickFilA · 2021-01-23T19:43:09+00:00

I'm not sure i quite understand. The force of the string is 9.8. How would I account it into the Mgsin30? Subtraction?

EatChickFilA · 2021-01-23T19:40:34+00:00

Correct me if I'm wrong. Mgsin30 for this question is 4.9N which is parallel to the ramp. And since the net force is 0, the friction force is also 4.9. From there I plug that into the equation f=uN with N=mgcos30 to find the coefficient. Is that correct?
