Answer:

One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.

Calculate the average atomic mass of a
Vesna [10]

Answer: 207.217 amu

Work:

203.973 amu *(0.014) = 2.855 amu

205.974 amu *(0.241) = 49.639 amu

206.976 amu *(0.221) = 45.741 amu

207.977 amu *(0.524) = 108.979 amu

2.855 + 49.639 + 45.741 + 108.979 = <em><u>207.217amu</u></em>

Kinetic and potential energy are two types of energy that relate too
Marysya12 [62]

Answer:

Option B. A tractor–trailer traveling at 80 kph.

Explanation:

Kinetic energy can be defined as the energy possessed by a body in motion. Mathematically, it is expressed as:

K.E = ½mv²

Where:

K.E is the kinetic energy.

m is the mass of the object.

v is the velocity of the object.

From the equation, K.E = ½mv²,

We can say that the kinetic energy (K.E), is directly proportional to both the mass (m) and square of the velocity (v). This implies that the greater the mass of an object, the greater the kinetic energy and the smaller the mass, the smaller the kinetic energy.

Now, considering the options given in question above, it is evident that the tractor–trailer has a greater mass than the car, cheetah and motor cycle. Hence, the tractor–trailer will have a greater kinetic energy even though they are traveling with the same velocity.
