So in the past with windows 7, my iphone would charge through the USB port even if I shut down my computer but after I upgraded to windows 10, my iphone will no longer charge from the USB port if my computer is in sleep mode or shutdown. It only charges if my computer is "ON." Is there any way to fix this?

I'm trying to buy something off a website but it says it is "not in stores." Aka, I can only buy it online, the problem is I don't have a credit card. I have a gift card but it does not cover the whole cost and then I have cash. Is there anyway to buy this product using cash/w/e's on my gift card if it is an "online" purchase only? Would I have to go to the store and basically turn my cash into straight up full gift card money then order it online? Would this make me lose money?(Do they charge tax/extra for charging a gift card) For example If I wanted to add $100 to a gift card would I just pay exactly $100 or would it be more?

This question was posted about 7 months ago but the one thing that was not answered is the part I need...

On the morning of April 10, 1912 the Titanic set sail from Southampton, England on its maiden voyage to New York City. On April 14, just four days into the trip, the Titanic struck an iceberg and in just over 2 hours the "unsinkable" Titanic was gone with a loss of 1,490 lives. The Titanic had been outfitted with 20 lifeboats, enough to hold about 54% of the passengers.

The table below gives a count of the survivors and victims of the Titanic sinking. The data are classified by type of passenger (first class, second class, third class, crew member) and survival status. The data for this analysis were compiled from the initial casualty estimates, as reported in the Official Board of Trade Inquiry Report, written originally in 1912. NOTE: For a complete list of passenger names see the poster on my office door. No, Leonardo DiCaprio is NOT listed.

survived died

first class 203 122

second class 118 167

third class 178 528

crew class 212 673

Question: What is the value of the test statistic for this hypothesis test?

I put in the values in my calculator to calculate the value but what I have is wrong... I have every other part of this questions correct just this one I cannot get. I'm assuming I'm putting in the wrong values for the expected column but I'm not sure. Currently I have

203, 118, 178, 212 in list1(for observed values) and (.323 * (survivors+dead)) for list2(expected). I got .323 from an earlier questions saying what is the probability that a random selected passenger survived.

Ok, I've searched on the net as to how it might be possible/ what programs to use to get rid of it, but the program did not get rid of it completely. What originally happened was, I could not access websites such as malwarebytes.com and spybotS&D's website, also whenever I used a search engine, it would redirect me to a random website. Here's the problem that still exists, when I try to run the program Malwarebytes or Spybot, the programs crash the instant i run it. I changed the name of malwarebytes and was able to run it, proceeded with a scan, and it found 9 infected files, which I cleaned. The anti-virus websites are no longer blocked but I still cannot run malwarebytes(if i change the name back to the original), Spybot, and search engines still redirect me. Could not run Spybot at all(even with name change) Tried things such as TrendMicro, Norman, Malware Cleaner, ThreatFire, Bitdefender, they all came up with nothing... Malwarebytes(fullscan this time) found 0 infected files....

1. A 550 g mass on a spring is oscillating at 0.80 Hz. The total energy of the oscillation is 0.48 J. What is the amplitude?

___ cm

2. A thin steel beam 6.0 m long is suspended from a crane and is undergoing torsional oscillations. Two 80 kg steelworkers leap onto opposite ends of the beam, as shown in Fig. 13.29. If the frequency of torsional oscillations diminishes by 20%, what is the mass of the beam?

____ kg

3.A 1.1-kg block (m1) rests on a frictionless surface and is attached to a horizontal spring of constant k = 28 N/m (see Fig. 13.33 below).The block is oscillating with amplitude 10 cm. A second block of mass m2 = 0.75 kg is moving from the right at 1.2 m/s. It strikes the first block when the latter is at the rightmost point in its oscillation. The collision is completely inelastic, and the two blocks stick together. Determine the frequecy and the amplitude of the resulting motion.

frequency = .619 Hz

amplitude = ___ m

1. A 240 g mass is attached to a spring of constant k = 5.4 N/m and set into oscillation with amplitude A = 26 cm.

(a) Determine the frequency of the system in hertz.

.755 Hz

(b) Determine the period.

1.32 s

(c) Determine the maximum velocity of the mass.

??? m/s

(d) Determine the maximum force in the spring.

1.40 N

2. A 500 g block on a frictionless surface is attached to a rather limp spring of constant k = 8.7 N/m. A second block rests on the first, and the whole system executes simple harmonic motion with a period of 2.3 s. When the amplitude of the motion is increased to 44 cm, the upper block just begins to slip. What is the coefficient of static friction between the blocks?

For some reason for number 1 I can't get part c, i've tried .027 and .03 but they are wrong. For number 2 I don't know why it's wrong either but i've gotten .40 and .39

A hollow ball is rolling along a horizontal surface at 2.3 m/s when it encounters an upward incline. If it rolls without slipping up the incline, what maximum height will it reach?

A 27 cm diameter circular saw blade spins at 3600 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?

A Navy jet of mass 10000 kg lands on an aircraft carrier and snags a cable to slow it down. The cable is attached to a spring with spring constant 43,000 N/m. If the spring stretches 23 m to stop the plane, what was the landing speed of the plane?

An airplane goes into a turn 3.1 km in radius. If the banking angle required is 29° from the horizontal, what is the plane's speed? Answer in km/h.

Please show steps at how you arrived at your answer. There was a similiar problem in the book with 3.6 km in radius and 28 degs. Their answer was 493 km/h. However, I do not know how to get to the answer. Book reference(Essential University Physics, by Richard Wolfson, Chapter 5)

It is a 1994 Toyota Corolla. Just recently, as I was driving home from school and going to park into my garage I stopped and was in the process of shifting my gears from D all the way back to P. However, right before I managed to go from R to P my foot slipped and i think the lever jammed. Now the lever gets stuck when I try to go from R to P. When I try to go from P to R there is some resistance but it is still capable to change the gear. When I drive the car, it works fine. However, every time when I try to park(Go from D all the way back to P). The lever gets stuck between R and P. (The order of gears form top to bottom is P, R, N, D, 2, L) What exactly is the problem here and how do I fix it? (I have checked the fluid levels and they are all fine). It is an automatic transmission.

Calculate the magnitude of the electric field at one corner of a square 2.30 m on a side if the other three corners are occupied by 2.70 x 10^-6 C charges.

Please show formulas and how you got to your answer. This is the last problem I need on my assignment.

A parallel-plate capacitor has fixed charges +Q and -Q. The separation of the plates is then tripled. By what factor does the energy stored in the electric field change?

Could someone show the formulas? I can't seem to find the right ones, I know it requires more than 1 which ends at 1/2 Q^2/C but i need the other formulas that derive C so that the distance will make an impact.

A ship, carrying freshwater to a desert island in the Caribbean, has a horizontal cross-sectional area of 2700 m^2 at the waterline. When unloaded, the ship rises 6.00 m higher in the sea. How much water was delivered?

There was an identical one in my book with a cross-sectional area of 2650 m^2 and the ship rose 8.5 m high. In which the answer was 2.44 x 10^7. However when i try to solve it i always get 2.25 x 10^7. Isn't it supposed to be 2650*8.5*1000? If not could someone show me what i'm doing wrong? Also, show steps and how you got to your answer. Thanks.

Four 6.5 kg spheres are located at the corners of a square of side 0.78 m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.

I have tried using the formula with Cavendish's constat it didn't work. I did Gm1m2/r^2 which i got my answer as 9.26E-9 which was WRONG. There is an identical problem in my book with 7.5 kg mass and .6 length of a square side. I did that one the same way and got the right answer in the back. 2.0E-8, could someone tell me how to do my problem correctly? Show steps so i can understand it.

9. In one of the original Doppler experiments, one tuba was played on a moving platform car at a frequency of 75 Hz, and a second identical one was played on the same tone while at rest in the railway station. What beat frequency was heard if the train approached the station at a speed of 13.0 m/s?

________ Hz

I got 5.69 but it's wrong. I found the two seperate frequencys using the dopplar effect formula then i subtracted the two and got my answer.
