Mark each statement as to whether it pertains to electromagnetic waves, mechanical waves, all waves, or no waves (false). 1 Can be Doppler shifted, reflected, refracted, diffracted, and can undergo constructive and destructive interference.
2 Consist of oscillating electric and magnetic fields.
3 Examples are sound, water, and vibrating guitar strings.
4 Wavelength is called pitch.
5 The frequency determines how energetic the photons are.

A All ways
B no waves
c electromagnetic waves
D mechanical waves

Examine the nuclear reacti why is this classified as a nuclear reaction rather than a chemical reaction? it is not balanced. a new compound is formed. a change has occurred in a nucleus. a new element has been formed.

Apiece of metal 75g at 110°c is dropped in a container with 500g at 20°c. the h2o if temperature is 24°c find specific heat capacity of metal

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
