  • Can you delete photos from your iPhone but NOT from icloud?

    Hey, all! So, I have zero available storage left on my iPhone 6s. I have around 500 photos, and I read that deleting the photos from the phone and backing them up elsewhere frees up a lot of storage. My only concern is that if I delete them off of the photo app on my iPhone, will they also be deleted from my icloud, or will they remain in one place but not the other? I ve tried looking this up and have gotten many conflicting answers.

    Thanks! :)

  • Is e^x a logarithmic function or exponential function?

    Probably a stupid question, I'm just confused as to which category e^x falls into. Thanks.

  • Use Euler s method with step size 0.1 to estimate y(2.5)?

    where y(x) is the solution of the initial-value problem y = 3y + 3xy, y(2) = 1. (Round your answer to four decimal places.)

    Does this mean I have to do Euler s method 25 times?

    I know that the formula for x1 =x0+h and so on and the formula for y1=y0+hF[x0,y0] but I don t know how to do this with a decimal? thanks

  • On inclined planes, is normal force always mg cos (theta) and gravity always mg sin (x)?

    In physics, is this always the case when you re working on problems sliding down an incline? Thanks!

  • By what distance is the spring compressed when the block momentarily comes to rest?

    An inclined plane of angle θ = 20.0° has a spring of force constant k = 520 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.45 kg is placed on the plane at a distance d = 0.273 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

    I know this is already on Yahoo Answers, but when I tried to follow the solutions, my answer of .106 was wrong, so please don't say "look it up". Thanks!

  • I suck at physics?

    I'm in college and I'm a pretty good student. I work very hard and dedicate many hours to studying. I'm in physics for scientists and engineers right now, and I'm just not getting it. I don't understand which equations to use and when, I don't know the theory behind the equations. I try doing what people recommend, Khan Academy, visualizing/sketching problems, listing relevant equations, reading the textbook, etc. I don't have a very good professor, too. Do you have any suggestions? Have you guys had similar experiences? Appreciate it.

  • A flare is dropped from an airplane flying at uniform velocity (constant speed in a straight line) Neglecting air resistance, the flare will?

    A. Quickly fall behind the plane

    B. Remain vertically beneath the

    plane

    C. Slowly gain horizontally on the

    plane

    D. Not enough information given

    Also, A rock is thrown horizontally on the Moon (where

    there is no air). The initial speed of the rock is v0.

    Assume the ground is perfectly level (and endless

    - it's a big moon) Which below is false?

    A. During the entire flight, the minimum

    speed of the rock is v0

    B. The rock's acceleration is constant

    during its flight.

    C. The time it takes for the rock to hit the

    ground increases, as v0 is increased

    D. D: (None of the above is false, they're

    all true)

    Thanks!

  • Can you help me on two easy physics vector problems please?

    I know these are so easy, but I just can't get them. The first problem is:

    A river flows downstream at 5 m/sec. You have a boat

    that is capable of traveling 7 m/sec relative to the water.

    If you aim the boat directly across the river which is 80

    meters wide you will encounter the opposite bank a

    distance downstream from the point you aimed at. The

    distance is? (the answer is supposed to be 45 m, but I'm not sure why?)

    The second question is:

    Arvin the Ant is on a picnic table. He travels 30 cm

    northeast, then 25 cm due north, and finally 15

    cm west.. What is the direction of Arvin’s net

    displacement?

  • What is the domain of ln(x^2-16x)?

    Hello, all. I know the derivative of this function is 2(x-8)/(x-16)x. The question wants the domain of f, not f'(x). when i try to solve, I set x^2-16x > 0, which gives you

    x(x-16)>0 which would mean that x>0 and x>16, right? Webassign says the answer is (-infinity, 0) U (16, infinity). Can you please explain? Thanks!

  • Quotient rule problem please?

    Hello! Could you guys please help me on this question?

    (8x^2+4x+6)/sqrt x

    So, I know that you use quotient rule which is gf -fg /g^2. When I do that I get:

    (sqrt x (16x+4) - (8x^2 +4x+6)(1/2 sqrt x))/x

    The part I m stuck on is how to deal with the complex fraction. Thanks!

  • What's the name of this song please?

    Hello all. This probably will make no sense... But here we go. It's by a Jamaican sounding guy, kind of like Shaggy, and it was popular in the 90s or 2000s. You literally can't understand anything he's saying ( or else I'd Google the lyrics haha) I know these clues suck, but it's all I have. Thanks
