How is an image from a CT scan made from 2D X-ray images? A. The 3D image uses only the parts of the 2D images that show
transmission of X-rays.
B. A computer combines many 2D images into a 3D image.
C. Several fuzzy 2D images are combined to make a clearer 2D
image.
D. The CT scan machine pastes many smaller 2D images together to
make a larger 2D image.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?
