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...
