1.A standard 1 kilogram weight is a cylinder 41.5 mm in height and 51.0 mm in diameter. What is the density of the material? (answer unit: kg/m^3) *2.A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure a. The atoms reside at the corners of cubes of side L = 0.160 nm. One piece of […]

I need help with creating a diagram of the detecting gamma camera setup. Please create in more detail and demonstrate clearly how the scatter material infront the detecting gamma camera.I have attached a picture of a very simple example but I need details in the diagram.
1. A 124-g rock traveling at a speed of 33 m/s hit a stick and moves back along its incoming path with a speed of 40 m/s. What is the impulse delivered to the tock by the stick? If the duration of the stick-rock collision is 0.0008s, what is the average force exerted by the stick on the rock?2. A fireworks rocket is shot straight […]

Calculate the magnitude of the induced emf when the magnet is thrust into the coil, given the following information: the single loop coil has a radius of 6.00 cm and the average value of B cos _ (this is given, since the bar magnets field is complex) increases from 0.0500 T to 0.250 T in 0.100s.
