nighttime college question I was wondering if I needed to fill in common app information when I'm just applying to cunys. o.o

nighttime science help needed If a 51 m steel footbridge experiences extreme temperatures between 18 C and 41C, what is the range in size of this bridge if it measure exactly 51 m at 23 C? (Steel has a coefficient of linear expansion of 1.1 x 10 ^-5/C). This is how I did it,but not sure if it is right. (51)(1.1x10^5)(59)=0.033099 (51)(1.1x10^5) (18)= 0.010098 0.033099-0.010098 =answer Thanks for the help in advance. :)

nighttime physic help needed A 5.00g bullet is fired into a 900g block of wood suspended as a ballistic pendulum. The combined mass swings up to a height of 8cm. What was the kinetic energy of the bulley immediately before the collision? The answer is 129J,but i dont get how to solve it. I think you got to use the potiental energy formula and kinetic energy formula,but im not sure. :( :(

nighttime stuck on physic question 1. A 40.6 kg box initially at rest is pushed 3.63 m along a rough, horizontal floor with a constant applied horizontal force of 199.789 N. If the coefficient of friction between box and floor is 0.477, find the work done by the applied force. The acceleration of gravity is 9.8 m/s Find the work done by the friction. Find the change in kinetic energy of the box.

nighttime stuck again with physics I don't remember how to do this. Please help me out. My last question for physic h.w. thank you guys for helping me in the pass. Physic isnt my subject :(. Two forces, 393 N at 15degree. and 279 N at 34degree. are applied to a car in an effort to accelerate it. Find the resultant of these two forces. Answer in units of N. Find the direction of the resultant force (in relation to forward, with counterclockwise considered positive, with -180 degree< θ <+180degree). Answer in units of degree.

nighttime Need help with science questions . 1.You weigh 255 lb on Earth (4.448 N = 1 lb). When you reach Alderon, you discover that its gravity is 1.85 that of earth. What is your weight on Alderon? Answer in units of N So for this is it just 255x4.448 then times 1.85? 2.A 10 kg block is pushed with a constant horizontal force of 20 N against a constant horizontal frictional force of 10 N. What is the acceleration of the block? would that be 1m/S^2? 3.Gravity on the surface of the moon is only 1/6 as strong as gravity on the Earth. What is the weight of a 20 kg object on the Earth? The acceleration of gravity is 10 m/s 2.Answer in units of N the answer was 200N. Then it asked me to find the weight object when it's on the moon which was 33.33333. The

nighttime Something Weird Happened I logged on to the ms website and I saw that the main character displayed below the play button was not mine. It was some random dude's character. o.o When I refreshed the page, it turned back into my main character. Did anyone else have a similar experience or know why this happened? :3

nighttime Physic question help What would the direction of the acceleration be if the ball is up in the air and almost going to reach its max height.

nighttime Need help with Physics again This question I have no clue how to do it. Please help me out. Explaining how to solve it would help me bunch. Thanks in advance. A model rocket is launched straight upward with an initial speed of 47.6 m/s. It accelerates with a constant upward acceleration of 2.07 m/s^2 until its engines stop at an altitude of 150 m. What is the maximum height reached by the rocket? The acceleration of gravity is 9.81 m/s^2. Answer in units of m When does the rocket reach maximum height? How long is the rocket in the air? [b]Edit[/b]:need help with this question too:An object is dropped from rest. What is its instantaneous speed when it has been in motion for 8 s? The acceleration of gravity is 9.8 m/s^2. Answer in units of m/

nighttime Help with physics homework I have been trying to solve these questions for a while but cant find the answer.So,if anyone is good at physic,help me out. :D The questions are: 1. A car starts from rest and travels for 7.1 s with a uniform acceleration of 2.4 m/s^2. The driver then applies the brakes, causing a uniform acceleration of -1.7 m/s^2. If the brakes are applied for 2.2 s, how fast is the car going at the end of the braking period? Answer in units of m/s 2.An electron has an initial speed of 1.92 x 10^5 m/s. If it undergoes an acceleration of 3.4 x 10^14m/s^2, how long will it take to reach a speed of 7.31 x 10^5 m/s? Answer in units of s Thank you guys in advance.Also,explain your answer [b]Edit[/b]:For what length of time is the el
