Answer:
Explanation:
ball ( it sound like thup thup it is softly harsh in voice )
book ( tak tak it is hard in voice )
bed ( pat pat it is soft in voice )
Door, window, picture, floor,stairs, wall, desk, backpack, paper, bed all of these produce different sound.
What do you mean by sound?The term sound is defined as an acoustic wave is a vibration that travels through a gas, liquid, or solid transmission medium. In terms of human physiology and psychology, sound is the brain's receipt of these waves and perception of them.
A mechanical disturbance that causes an equilibrium condition to be disturbed and propagates by an elastic material medium.
The vibration of an object creates sound, which travels from one place to another by a medium. Vibration is the phrase used to explain an object's to-and-fro or back-and-forth motion. Vibrations are generated by objects in motion.
Therefore, stairs, wall, door, window, picture, floor, desk, backpack, paper, bed all of these produce different sound.

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?
Answer:
The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Explanation:
Answer:
For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.
Explanation:
can someone help me with this please
Which object would have the most momentum?
A.a 500-pound car moving at 20 miles per hour
B.a 200-pound car moving at 60 miles per hour
C.a 100-pound car moving at 80 miles per hour
D. a 50-pound car moving at 100 miles per hour
Answer:
B
Explanation:
Momentum is the product or multiplication of a body's mass and its speed.
Since all options have the mass and speed in the same units, there is no need for conversion.
A. 20 x 500 = 10000, B. 200 x 60 = 12000
The same goes for the rest!

What would happen if you touched an object that is the same temperature as your hand? Would any heat transfer happen? Explain your answer in 4-5 sentences.
Answer:
Explanation:
When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object
which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms
