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

Answers

Answer 1

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!

Answer 2
So I did this in my science class and my teacher explained this and I don’t know know how to explained to you so am just gonna tell you the answer the answer is A

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.

Answers

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

What is a characteristic of a gas?

Answers

Answer:

Gases have three characteristic properties: 1. they are easy to compress, 2. they expand to fill their containers, and 3.they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.

Explanation:

Gases consist of particles in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container.

What does the Law of Conservation of Momentum stare about the momentum in a system in an inelastic collision?

Answers

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.

A 1000 kg boulder sits at the top of a 50-meter high cliff. Determine the amount of potential energy possessed by the boulder if the acceleration due to gravity is 9.8 m/s2. The boulder has_______(magnitude/ number)_______(units) of Potential Energy.

Answers

Answer:

490000J

Explanation:

Given parameters:

Mass of boulder  = 1000kg

Height of cliff = 50m

Acceleration due to gravity  = 9.8m/s²

Unknown:

Potential energy  = ?

Solution:

Potential energy is due to the position of a body. It is expressed as;

        P.E  = mgH

m is the mass

g is the acceleration due gravity

H is the height

  Now insert the parameters and solve;

            P.E  = 1000 x 9.8 x 50  = 490000J

Data:  

m = 1000 kg

h = 50 m

g = 9.8 m/s^2

Find:  

P.E = ?

Formula:  

P.E = mgh

Solution:  

P.E = mgh

P.E = (1000)*(9.8)*(50)

P.E = 490000 J

Result:

P.E = 490000 Joule
