Problem A block is dropped onto a spring that is attached to the ground. The block follows the pathway shown in the diagram below and passes through positions 1-3. The block is dropped at position 1, has fallen to the spring without compressing the spring at position 2, and has been momentarily stopped by the compressed spring at position 3. The height of zero (y=0y=0y, equals, 0) is marked on the diagram below.

The diagram shows a block's pathway as it falls onto a spring. Position 1 is at the moment the block is dropped above the spring. Position 2 is just before the block hits the spring. Position 3 is at the block's lowest point where the spring momentarily stops the block.

How much work is done lifting a 9.10 kg box straight up onto a shelf that is 1.80 m high?

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?

Fill in the blanks with the numbers is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
