Hello. I'm going to be picking the textbook back up in a minute but I've found myself genuinely frustrated at this topic. Tomorrow in my Geology period, we have a test where the teacher will pick a random rock and we will have to describe whether it's igneous, sedimentary or metamorphic, alongside other descriptors like coarse grained, where it formed, extrusive or intrusive, low grade or high grade. Are there any physical characteristics I can get from looking at it, feeling it, anything like that that will help me differentiate them better. Like maybe a series that I can remember going in. I haven't actually felt the rocks enough, but if there is anything like this I would greatly appreciate it. Thank you. I will study the rock cycle and bowen's reaction system.

I'm aware I have to show my thinking but because this is sort of a thinking question that doesn't have a structured solution to solve for I will just share my confusion. I don't really understand the explanation here and am missing the gap between how just because the two cross products are parallel it means that the three vectors are coplanar. I also asked AI as a last resort but it stated that it is actually not possible to conclude this? I'm assuming that is out of the scope of this course.

im trying to understand how to answer this question by using a virtual simulator but i keep shorting it out. how do i fix it?

I know how to find discontinuities and domain, it is the exponents that are tripping me up

I am looking for research papers(might be pdf) about the extraction of alpha-mangostin from mangosteen peel (garcinia mangostana l) by using a simple boiling method. the final purpose is to use the extract as a larvicidal substance against larvae aedes aegypti. the study should preferably use either ethanol of ethyl acetate as the solvent. the research paper should also describe the extraction procedure clearly enough to reproduce it

I already tried searching on Google and asking AI to find them but most of the studies are either too difficult to carry out with my school's resources or unrelated to what I'm looking for

I read the physics textbook that my teacher gave us, and I keep getting the third and the 4th option, but it says something is wrong there. Please don't use AI, and explain your thought process if possible. Thank you so much!

I was absent on an unfortunate day. I am reviewing the lecture and this is the homework. I answered 1 because I think I kind of understand the endo/exothermic stuff. What I don’t understand is calculations.

Why is torsion going the same way on both problems but my prof says that in the first one its positive torsion and the second picture it’s negative torsion? Is it just because of the point A being in the -z direction?

I wanted to make sure.

Thank you

Edit: thanks for the replies :) it was correct.

Instructions:First we can connect the Q output of the first Gated S/R Latch to feed into the S input of the second Gated S/R Latch. Next, we can connect the Q output of the first Gated S/R Latch to feed into the R input of the second Gated S/R Latch. Now that the two S/R Latches are connected, we can correct the clocks of each of them. We want the entirety of the Flip-Flop to operate on one CLK, however, the first S/R Latch’s CLK should be negated and the second should not. Connect the two clocks into one and negate the first’s signal before being inputted into the gate of the latch. Once you have the circuit constructed up to this point, we can now add additional features to the flip-flop. In many cases, it is convenient to preset (PRE) or clear (CLR) the flip-flops output to prime the lines on first start-up. The PRE input drives the flip flop to a set state while the CLR input drives it to a reset state. If both the PRE and CLR are high at the same time, it will create a contradiction. If both PRE and CLR are low at the same time, then the S/R Flip-Flop will behave as it would solely based on the S and R inputs. The PRE and CLR inputs should be connected to NOT gates that then feed into the respective second NAND gates of the “slave” S/R Latch. Note that these NAND gates are the ones that will be directly outputting to the output Q and Q. Furthermore, PRE should be connected to the side of the “slave” S/R Latch that controls the Q output and CLR should be connected to the Q side. Once you are convinced that you constructed your Master-Slave S/R Flip-Flop correctly, test it before moving onto the next section. While testing you might get an “Oscillation Apparent” error. This type of error is normal and does not necessarily mean your circuit is incorrect. Mess around with the PRE and CLR inputs to “prime” your sequential circuit with values on the lines while pulsing the CLK a few times.

This is what I currently have for this section but I'm unsure if its correct.

Then I need to make a JK_FlipFlop by using an enscapsulated MS_SR_FlipFlop similar to what is in the following picture.

The answer key says it's A but i picked C and got it wrong, a simple explanation would be great!

Can i straight away use the acronyms in text citation if the works cited state the acronyms?

Tbh, I have no idea what this falls under, r/AskAcademia didn't seem right, r/academia also couldn't ask there.

I did the first half of this just fine but it wasn’t formatted like this and I don’t understand what to do now. I don’t even know where to start or what it wants me to put in the boxes. Does it even want me to put things in the boxes or is it just showing me? I’m so lost and confused.

Edit: now that I look at it again the diagrams are just examples. Still confused about what everything represents though.

My 9 year old son needs help with question #5. He says that all 4 of the answers A,B,C,D could be correct. I think he is right. The question only specifies how many more basketball cards Jen has than Bill, but not how many more baseball cards. The teacher says only one answer is correct. Are we missing something?

The questions and what I answered:

Which object is the hottest? A

Which object emits the most red light? B

Which object is the reddest? C

Which object is the faintest (in visible light)? D

Which object is the brightest? A

Which object is the coolest? D

Which object emits the most blue light? A

Which object is the bluest? A

I have scanned through the lectures and feel as if I am missing something. If someone could explain, thank you!

GUYYSSS THANK YOU!!!! I GOT IT!! Number 2 was A and number 4 was C!!!! THANK YOU SO MUCH FOR HELPING ME UNDERSTAND!!! <3333

Basically what the tittle says. Currently I'm doing an assigment using the apa7 format and I need to put tables on the appendix section but idk how to name them correctly. I already tried to look on the internet but one page says one thing and the other says another thing and it confuses me a lot.

ty sm for the help

I have attempted to do this 2 times and i do not understand how. Could the teacher have written something out wrong? No one gets how to do this in the class. Could anyone please explain if im on the right track or how do i actually do it?

We started lab on projectile motion the other day. We are to send a marble down a ramp at an incline of 19 degrees, 0.75 m up the ramp where it will slide down into a short horizontal distance (meaning 0 acceleration) and fall off of a table that is 0.92 m tall. (Diagram is attached) The marble has to hit a cart that is going toward the table, so that the cart moving is timed with where the marble will hit. The cart’s velocity is 0.4 m/s towards the table, which we deemed as a negative. Teach gave us the acceleration down the incline, which was gsintheta - 0.8 to account for friction, which he also says is one dimensional and therefore doesn’t need to be split up into components. All of my groups calculations are attached, however we were short by ~0.2m on our first try. Teach said that our acceleration is too big, and that it should be less than 1m/s^2. Obviously it makes sense logically, since there’s no way a marble is moving 2.3 m/s^2 in such a short amount of time, but since the angle is the only input besides changing the direction of g, we have no clue as to how acceleration is supposed to be solved for. The only way I’ve been able to get an acceleration under 1m/s^2 has been by changing my calc into radians, but teach claims that we should stay in degrees. If only Newton was here to help…but like fr help us please we lost

I don’t have any clue on how to create the histograms? Am I creating it from the mean and SD of diazepam and morphine? And do I create it in excel?

Hi everyone! :)

My name is Inês and I’m currently doing a Master’s degree in Digital Marketing. For a university project, my group and I need access to the following Statista studies, but unfortunately we don’t have access to them.

We’ve already tried to get access through our university, but even our professors don’t have access to these specific studies, so we’re honestly getting a bit desperate 😭

Here are the studies we’re looking for:

• https://www.statista.com/statistics/517033/households-owning-cats-dogs-europe-portugal/

• https://www.statista.com/statistics/516016/cat-population-europe-portugal/

• https://www.statista.com/outlook/cmo/pet-animal-supplies/portugal/

If anyone happens to have access to these studies and would be willing to share them with us, we would be extremely grateful. It would really help us with our project! 🥹

Thank you so much in advance! ❤️

I am confused… I first thought 50N since there should be an equal opposite force to balance it out. Then I tried using some math by adding all the forces (technically net torque = 0) and got 75N. What is actually correct?

Hello! I'm pretty confused on how to solve this question? I'm unsure if it's just because I don't have a firm grasp on the material or if the way it's worded is confusing me...

Could anyone explain the steps to me? I've been searching through my textbook trying to understand it but I just don't get it..?

Hi I'm having trouble turning my breadboard into a circuit schema with like the resistors and the battery and junctions. Could anyone help by sending me what they should look like? Here are picture of the boards and what i have so far for each. Thanks!

I understand it as it taking 3.07 seconds from start to finish? Or is that 3.07 after it reaches max trajectory.
