1. (-/2 points) DETAILS SERCP11 13.1.P.006. MY NOTES ASK YOUR TEACHER An archer must exert a force of 330 N on the bowstring shown in Figure (a) such that the string makes an angle of 0 = 30.5º with the vertical. (a) Determine the tension in the bowstring. N (b) If the applied force is replaced by a stretched spring as in Figure (b) and the spring is stretched 33.0 cm from its unstretched length, what is the spring constant?...

19. [-13 Points] DETAILS SERPSE10 29.1.OP.003.CTX. MY NOTES ASK YOUR TEACHER You are performing studies of the possibility of migrating birds using the Earth's magnetic field for navigation. To modify the magnetic field in the brain of a bird, you fit the bird with coils as "caps" and "collars" as shown in the figure below. The data on the coils indicate that they each have 210 of resistance, a radius of 1.20 cm, and 50 turns of wire. The centers...

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A conducting rod of length 1 - 35.0 cm is free to slide on two parallel conducting bars as shown in the figure below. Two resistors R. - 2.000 and R, - 5.000 are corected across the ends of the bars to form a loop. A constant magnetic field 8 - 2.95 T is directed perpendicularly into the page. An external agent pulls the rod to the...

DETAILS 5. [-/6 Points) SERCP10 13.P.016. MY NOTES ASK YOUR TEACHER A 0.268-kg block resting on a frictionless, horizontal surface is attached to a spring having force constant 83.8 N/m as in the figure below. A horizontal force i causes the spring to stretch at a distance of 5.10 cm from its equilibrium position. (a) Find the value of F. (Enter the magnitude of the force only.) N (b) What is the total energy stored in the system when the...

A tabletop model rail gun (see figure below) consists of two long, parallel, horizontal rails l = 3.80 cm apart, bridged by a bar of mass m = 2.95 g that is free to slide without friction. The rails and bar have low electric resistance, and the current is limited to a constant I...
