Nature of light

Light is transverse and electromagnetic radiation that exhibits the properties of a wave as well as a particle. For this reason, light is said to have a “dual nature.”

Question 8. In a classroom demonstration, two identical low-friction dynamics carts are pushed toward each other such that they are travelling at the same speed when they collide. Immediately after the collision the carts come to a complete stop. The teacher challenges his students to describe this collision. Some of the students' descriptions are provided below. I II III IV Student Descriptions of the Collision of Two Carts Before the collision occurs the carts have the same momentum. Before the collision occurs the carts have the same kinetic energy. This collision is an example of an elastic collision. This collision is an example of an inelastic collision. The descriptions that are appropriate for this collision are A. I and III B. II and III C. II and IV D. I and IV
3-D Explosion Group Challenge A large bomb was planted on a train and it exploded into eight pieces! The mass and velocity of each piece (relative to the ground) is given in the table below. All the masses are in kilograms and the velocities are in m/s. Determine the velocity of the train at the moment the explosion occurred. This is not actually that much work. Let's make SURE that the answer is totally correct, neat and clear. It is to be submitted before the start of the next class, one per group.
