A heavy iron ball is placed in an aluminum pie pan that floats in a bucket. The water level at the side of the bucket is marked. Then the ball is removed and allowed to sink in the bucket. The water line at the side of the bucket.
a. rises
b. goes down
c. is the same

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
