1. ### What is the total magnetic flux through the plastic of the soda bottle?

Homework Statement An open plastic soda bottle with an opening diameter of 2.7 cm is placed on a table. A uniform 1.95-{\rm T} magnetic field directed upward and oriented 21^\circ from vertical encompasses the bottle. What is the total magnetic flux through the plastic of the soda bottle...
2. ### Shroud of Turin

Whenever people try to disprove the shroud they always try to argue with carbon dating, but I think there may be a much easier argument which is: It seems quite clear that the Jesus in the shroud has long hair, just like we would expect, but many biblical scholars and archeologist believe...
3. ### Bird Collision Problem

Never mind I was doing it correctly, I just kept making some unknown calculation error that kept giving me the wrong angle.
4. ### Bird Collision Problem

Pretty much I did p=sqrt(p_1_^2 +p_2_^2 But I realize that is wrong because its not elastic situation, I know is inelastic, but not perfectly inelastic so I used the second equation thinking that would work, I'm not quite sure were to go from there.
5. ### Bird Collision Problem

Homework Statement To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. In one such episode, a 620 g falcon flying at 20.0 m/s hit a 1.40 kg raven flying at 9.0 m/s. The falcon hit the raven at right angles to its original path and...
6. ### Finding acceleration of two blocks with pulleys

Homework Statement In terms of m_1, m_2, and g , find the acceleration of the first block in the figure . There is no friction anywhere in the system. http://session.masteringphysics.com/problemAsset/1038627/5/YF-05-71.jpg Homework Equations The Attempt at a Solution I know...
7. ### Direction of velocity

Haha just to be safe I decided not to round at all and got the answe 8.9 still wrong, but I used 3 sigfigs and got 9.2 which it accepted for 9.1 thanks for your help. Im just glad to know it was mastering physics this time and not me.
8. ### Direction of velocity

This is the complete problem statement: A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53 ^\circ, and is supposed to be caught by Joe Bob, whose hands are 6.1 {\rm m} above and 8.2 {\rm m} horizontally from her launch...
9. ### Direction of velocity

I meant 14 but I did replace that 8.6( bad reading on my part) with 8.2 which gave me a new v_y of 1.64 so arctan=(1.64/8.42) gives me 11 degrees above the horizontal which is still wrong
10. ### Direction of velocity

v_x=14cos53= 8.42 V_y=13sin53- 9.8(8.6/8.42)=1.17 These two answers then gave me 8.4 according to mastering physics, which was the answer to part B of this problem I got t for the v_y equation from x=v_0 cos (theta) t which I used to help me find the initial velocity for part A of this...
11. ### Direction of velocity

sqrt)v_x^2+v_y^2 my actual answer was 8.5 but mastering physics rounded it down to 8.4
12. ### Direction of velocity

Homework Statement A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53 ^\circ, and is supposed to be caught by Joe Bob, whose hands are 6.1 {\rm m} above and 8.2 {\rm m} horizontally from her launch point (the figure )...
13. ### Find initial velocity with accelration as a funt. of t

Perfect, integrated twice set x to 0 gives me -4.25 m/s Thanks a bunch
14. ### Find initial velocity with accelration as a funt. of t

Homework Statement The acceleration of a particle is given by a_{x}(t)= - 1.94 m/s2 +( 3.05 m/s3 )t. Find the initial velocity v_{0x} such that the particle will have the same x-coordinate at time t= 4.00 s as it had at t=0. Homework Equations vx= v0x + the integral ax dt The...
