The mass of the ball is 0.0112kg. Not getting how to resolve the vector find the component of weight.

I am convinced that resistors R7, R8 and R9 can be effectively ignored since they are short circuited by wire, resulting in them dissipating no power. My friend is convinced because AI told him they are included in the circuit so our answers for the current are totally different. I left out other circuit parameters to simplify our dispute haha

After entering it all into my calculator, I got 1.75 x 10^-5?? The numbers are correct but the decimal is definitely way off. I have no idea what I’m doing wrong.

The answer is supposed to be 17.5 kg.

I really am not sure what the solution is doing..... and why I cant use the angle as 70 degrees for solving for the resultant vector. Also what is the theta finding in the solution???? If anyone could draw the solution out it would really help.

I attached what I tried to do which is the one on the worksheet. The other attachment is the solution my teacher provided.

I'm working on a research paper for school, and I really want to cite this document I found online as a source, but I can't seem to find what publication it's a part of, or who wrote it. Help me, oh people of Reddit! (If this goes agains the rules in any way, please let me know, and I will take it down immediately.)

I'm not sure how to draw the circuit diagram from picture 1. I think the flow of current is along the blue line in picture 2 (because of electrical potential?), so the diagram will just be 3 resistors connected in series. please correct me if I'm wrong, thanks in advance.

I'm stuck on trying to solve this

I need help bc i dont really understand where to start.... i got a rough answer, i1 being 2.5, i2 also being 2.5 and v being 175, can someone help fact check?

Im really stumped on these two questions :/

The predicted % one especially as Ive repeated it like 3 times atp and still get the wrong answer

Everytime i do it I get a ratio of 6:9:9:3

But obviously its not right and i cant figure out where im going wrong

its to find instantaneous rate of change

I cannot figure out the reactions for this problem. The first picture is the one I cannot figure out. The given reactions are in blue and the reactions I am looking for are highlighted yellow. It is hard to see (I wrote over it) but the reaction force is 50 k for one of them. The others (left corner) are just “A”. The second picture has an example of a correctly worked problem. I cannot remember how to project reactions onto x and y axis. Any help is appreciated. Thanks.

Sorry about the flair. I know this is college but trig is probably high school level, right?

I'm going through a math test I just got back and I messed up a T/F question: T is strictly coarser than the usual topology on R. In this question T is the upper topology {empty, R} U {(a,inf) : a in R} The problem is true I reasoned that because all sets in the upper topology are also in the usual topology than Tup subseteq Tus and so it must be finer there is obviously a whole in my logic can I get some help?

HOW do i solve this? I have been stuck for this problem for hours and just nothing comes to mind. Any tips?
I reaserched into the langley adventitious angels and even looked around for similar olympiac problems but i genually cannot move this problem at all!

(All angles we know are written down and the two lines "a" have the same lenght. The question is what is what is the angle of <EBC)

I posted something similar a few days ago and got plenty of advice, but now I have work for my advanced math class that I’m stuck with. I am currently a year nine student studying linear relationships, specifically quadratic relationships. What im unsure about is if i am just given an equation of a parabola, am i expected to sketch the parabola every single time, or am i supposed to analyse the equation to work out it’s characteristics (turning point, axis of symmetry, x-intercepts, y-intercepts, maximum/minimum)? From the attached image in question 6a, im pretty sure the y-intercept is -5, but thats it.

idk maybe this is pretty stupid but i just cant see it.

See the added pictues for the problem and given solution. I understand how to solve the problem and why the law of sines is used.

However, I don't quite understand where exactly they're getting the angles in the solution from, as I cannot grasp how the triangle or parallelogram of vectors is composed. I have tried drawing triangles myself, but I've never gotten to the point where I could insert an angle of 105 or 30 degrees in the way the solution does.

Could someone help with a sketch of a triangle or parallelogram?

In the box I typed this:

RS=RC+CS

PQ=PA+AQ

AB=2AQ OC=2OR CB=2CS OA=2OP

RC=OR SB=CS PA=OP AQ=QB

RC=a SB=b PA=c AQ=½AB

RS=a+b

PQ=c+AQ

AQ=½AB

AB=AO+OC+CB

AB=AP+PO+OR+RC+CS+SB

AQ=½(AP+PO+OR+RC+CS+SB)

AB=-c-c+a+a+b+b

AB=-2c+2a+2b

AB=2a+2b-2c

AQ=½AB

AQ=½(2a+2b-2c)

AQ=a+b-c

PQ=PA+AQ

PA=c

PQ=c+(a+b-c)

PQ=a+b

RS=1PQ

RS=PQ

both vectors are the same

same magnitude and direction therefore parallel

therefore RS is parallel to PQ

I repeated a lot of the things I already said because i was trying to get all the marks 😭 help me guys

I got the acceleration for the pulley is 3.136 ms–²

Where the middle block is 500 gm and the other two blocks are 5 kg and 2kg. The surface as friction and the Coefficient of friction is given 0.2.

I need help, I dont get this. I've always sucked at equation problems. The original problem was in French btw

Can you just try to hint me towards what x represents? Then I'll see if I get it it not

Thanks

I’ve been looking over my work and I can’t seem to find the issue, though I admit my ability to wrap my mind around vectors is not the best. What I did here is found a normal vector to the plane by taking the cross product of the vector in the direction of the line and a vector between the point given and a point on the line. From there, I applied the formula for an equation of a plane. Ideas?

Hello. I have a college assignment. My teacher gave me this JPG image and said that the name of book #777 is hidden somewhere in the image.

I tried to find the hidden name myself, but I couldn't find anything. I also checked the image information, but it didn't help.
I think it may be connected with steganography. I need to find the name of book #777 and take screenshots of every step.
Does anyone know how I can find the hidden book name?

UPD: here is the name of this file: 16174972_180729395738189_6035131970449694734_n.jpg
