Bottles of perfume sometimes have thick glass (n = 1.5) walls which give the impression the volume is larger than it is. Assume a cylindrical bottle has an inner radius of 1.0 cm and an outer radius of 2.0 cm. How thick (in em) would the wall appear if you could see a mark on the inside surface? a. 0.80 b. 0.51 c. 0.72 d. 80 e. 12

I am not sure how to start these problems as I am given very limited information and am told that I have everything I need to complete them. We are given these equations as well to use for the problem.

A car initially traveling eastward turns north by traveling in a circular path at uniform speed as shown in the figure below. The length of the arc ABC is 247 m, and the car completes the turn in 33.0 s. Need the answer for C in degree format not coordinates  An x y coordinate axis is shown. Point A is located at a negative value on the y-axis, and an arrow points from point A to the right. A dotted line curves up and to the right in a quarter circle until it reaches point C on the positive x-axis. An arrow points directly upward from point C. Point B is on the dotted circle. A line drawn from the origin to point B makes an angle of 35.0° below the x-axis.   (a) Determine the car's speed. ___________ (b) What is the magnitude and direction of the acceleration when the car is at point B? magnitude       ___________ m/s2 direction _______________  ° counterclockwise from the +x-axis

Need help figuring out: Using the standard cartesian coordinate system, which of the following vectors have a NEGATIVE X-COMPONENT? Choose all that do.

Please help with the solution to this problem using (km/s). I know we will use Hohmann Transfer and a combined plane change.    In the opening scene of the movie “Gravity” Dr Ryan Stone (Sandra Bullock) and Matt Kowalsky (George Clooney) are required to transit from the Hubble Space Telescope (Altitude 600 km, 28.5 degree inclination) to the International Space Station (Altitude 400 km, 51.6 degree inclination) using nothing but their Manned Maneuvering Units (MMU). An MMU has a delta V capability of about 30 m/s, and it would be impossible to perform this maneuver with so little delta V, but… a.) How much delta V would be required for this maneuver? b.) What if the maneuver did not require an inclination change (altitude change only?)

Stuck need help! The class I'm taking is physics for scientists and engineers! Problem is attached. please view attachment before answering.  Really struggling with this concept. Any help will be greatly appreciated! Please detail explain so I can fully understand how to solve.  Thank you so much.

A student walks 550 m [E], then 450 m [N30°W], and finally 350 m [S10°W]. Using the component method, find the resultant (total) displacement). Show your work and round your answer (magnitude and direction) to appropriate significant digits.

Jungle gym, dot products, unit vectors. A coordinate system is laid out along the bars of a large 3D jungle gym (the figure below). You start at the origin and then move according to the following steps. For each step, the distance (in meters) and direction in which you move A. are given by the cross product A x B of the given vectors A and B. For example, the first move is 18 m in the +z direction. What is the magnitude dnet of your final displacement from the origin? (a) A = 3.01, B = 6.0 (b) A = - 4.01, B = 3.0k - (c) A = 2.0₁, B = 4.0k (d) A = 3.0₁, B - 8.0 (e) A = 4.0K, B = - 2.01 (f) A = 2.01, B - 4.01

Choose one equation (and only one) from the equation sheet that would let you solve the problem posed. Then define which variables in the equation go with what numbers from the problem itself (not from other problems), and define which variable is being solved for. Do not actually solve the problem numerically or algebraically, just pick the one equation and define the relevant knowns and single unknown. Don’t forget to include direction when called for by a vector variable. 1) A single mole of Carbon Dioxide has a mass of 44 g, and at 1.00 atm of pressure and 20oC (293K) it occupies 22.4 liters. At what speed will you find the peak of its speed distribution function?

A ferris wheel has a radius of 75 feet and its center is 80 feet above the ground. You ride the wheel once around and get off. (a) Find a function that expresses your height in terms of the angle of rotation of the wheel since you boarded. Be sure to give the function a name and define its input and output (with units) in complete sentences. Include the function's domain. Explain your reasoning clearly. (b) When you are 108 feet above the ground for the second time, the wheel comes to a stop. It then turns through a small angle and stops again. Ap- prorimate the change in your height in terms of this small angle of rotation. Be sure to define these changes precisely and to erplain your logic. (c) Suppose the wheel turned through an angle of 2° as described in part (b). Use your result of part (b) to approximate the change in your height. Include units at each step and for each number in the computation. Craft your response to this question in the form of a letter to a friend.…
