Thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object.

Here 'conserved' means that the amount of thermal energy lost of by one body is exactly equal to the amount of thermal energy gained by another body, which is the statement of the first law.

According to second law, we do not see objects warming up on their own. For example, if we have a cup of coffee left to itself, we would always see that it cools down. Here, thermal energy is being transferred from warmer object (coffee) to cooler objects (the air in the room).

What is the potential energy of two electrons that are separated by a distance of 3.5 x 10^-11m ?
Simora [160]

Answer:

6.58×10⁻¹⁸ J

Explanation:

Applying

E = kq²/r.................. Equation 1

Where E = potential energy, q = charge on each electron, r = distance between the electron, k = coulomb's constant.

From the question,

Given: r = 3.5×10⁻¹¹ m,

Constant: q = 1.6×10⁻¹⁹ C, k = 8.99×10⁹ Nm²/C²

Substitute these values into equation 1

E = (1.6×10⁻¹⁹)²(8.99×10⁹)/(3.5×10⁻¹¹)

E = 6.58×10⁻¹⁸ J

Average speed can be represented by the mathematical expression
nevsk [136]

Average speed is defined as total distance moved in total interval of time

so it is given as

v_{avg} = \frac{distance}{time}

now here is we show distance by "d" and time by"t"

then we will have mathematical expression as follows

v = \frac{d}{t}
