In the grating equation $n\lambda =d\mathrm{sin}\theta$ , the quantity $\theta$ will be determined in the lab: using meter sticks and geometry/trigonometry, using the angular scale on the experimental apparatus, using a protractor?

For tests using a ballistocardiograph, a patient lies on a horizontal platform that is supported on jets of air. Because of the air jets, the friction impeding the horizontal motion of the platform is negligible. Each time the heart beats, blood is pushed out of the heart in a direction that is nearly parallel to the platform. Since momentum must be conserved, the body and the platform recoil, and this recoil can be detected to provide information about the heart. For each beat, suppose that 0.050 kg of blood is pushed out of the heart with a velocity of +0.30 m/s and that the mass of the patient and the platform is 85 kg. Assuming that the patient does not slip with respect to the platform, and that the patient and the platform start from rest, determine the recoil velocity.

A 230kg crate hangs from the end of a rope of length L=12.0m. You push horizontally on the crate with a varying force F to move it distance d= 4.00m to the side.

a) What is the magnitude of F when the crate is in this final position? What are b) the total work done on it, c) the work done by the gravitational force on the crate, and d) the work done by the pull on the crate fromthe rope? e) Knowing the the crate is motionless before and after its displacement, use the answers to (b), (c), and (d) to find the work your force F does on the crate. f) Why is the work of your force not equal to the product of the horizontal displacement and the answer to (a)?

Hi I need help with thisquestion.
A uniform metal rod, with a mass of 3.1 kg and a length of 1.2 m,is attached to a wall by a hinge at the base. A horizontalwire bolted to the wall 0.51 m above the base of the rod holds therod at an angle of 25 degrees above the horizontal. The wireis attached to the top of the rod. (a) Find the tension inthe wire. (b) Find the horizontal and verticalcomponents of the force exerted on the rod by the hinge.
Thank you

Two children, Ferdinand and Isabella, are playing with a waterhose on a sunny summer day. Isabella is holding the hose in herhand 1.0 meters above the ground and is trying to spray Ferdinand,who is standing 10.0 meters away. I know so far that she cannotspray Ferdinand at the current position and with the curreentspeed of spray. I got stuck inthe following question:

To increase the range of the water, Isabellaplaces her thumb on the hose hole and partially covers it. Assumingthat the flow remains steady, what fraction f of the cross-sectional area of the hose hole does shehave to cover to be able to spray her friend?
