X-rays are often used in medical settings to create images of the body's internal structures such as bones. This is made possible by the fact that X-rays are able to pass through the body's softer tissues without being absorbed. Radio waves are also able to pass through the body's softer tissues without being absorbed. Why are radio waves not used to generate medical images? A. The electrons in most atoms are not in high enough energy states to absorb the photons of radio waves.
B. Radio waves tend to bend too much when they encounter solid materials to be used for generating accurate images.
C. Radio waves carry so little energy that they tend to pass through most atoms without an interaction taking place.
D. The frequency of most radio waves is too low to allow them to pass through bones or other solid materials.

    m₁v₁ + m₂v₂ = (m₁ + m₂)vmomentum is conserved.the left-hand side of the equation represents the momentum in the system before the collision.the right-hand side represents the momentum in the system after the collisionm₁ and v₁ represents the mass and the velocity of the physics blockm₂ and v₂ represents the mass and velocity of the ball of puttyv represents the final velocity of the combined mass.the question states the two masses stick together. they combined mass has its own velocity with the body mass the sum of the two objects' massestheir combined momentum is (m₁ + m₂)vto find the magitude of (m₁ + m₂)v, we need to add the vectors on the left-hand side of the equation: m₁v₁ + m₂v₂.note the diagram. i have positioned the vectors in accordance with their directions.the magnitude of the resultant can be calculated using the pythagorean theorem since this is a right triangle situation (north and west are perpendicular)|(m₁ + m₂)v| =  √[ (m₁v₁)² + (m₂v₂)² ]|(m₁ + m₂)v| =  √[ (1.5kg·8.0m/s)² + (0.40kg·20m/s)² ]|(m₁ + m₂)v| =  14.4 kg m/sfor two significant figures (assuming that 20m/s is two), this rounds to 14 kg m/s
