60 kilometers in 4 hours, what is the average speed?​

Physics
1 answer:
allsm [11]3 years ago
8 0

Average speed = (distance covered) / (time to cover the distance)

Average speed = (60 kilometers) / (4 hours)

Average speed = (60/4) kilometer/hour

<em>Average speed = 15 km/hr</em>

The behavior of gas are dependent on all of the factors
Slav-nsk [51]

Answer:

Explanation:

Pressure (P): the force exerted by gas molecules as they strike a given surface.

Volume (V): the space occupied by gas molecules.

Temperature (T): A measure of how fast gas molecules move (kinetic energy).

Amount (n): Amount in moles of gas molecules.

Q1- the speed will increase because the particles will have more energy which causes them to move faster
trasher [3.6K]
<h3># Question </h3>

Q1- the speed will increase because the particles will have more energy which causes them to move faster

Explanation:

<h3>With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. </h3>

If a second resistor with R2 = 19.0 Ω is connected in series with R1, what is the total rate at which electrical energy is dissi
luda_lava [24]

Total rate at which electrical energy is dissipated by the two resistors are V²/R  or I²R.

<u>Explanation:</u>

When the two resistors are combined in series then the total resistance gets added.

If R_{1} and R_{2} are in series then total resistance, R =

Total resistance becomes R_{1} + 19 Ω

The total electrical power dissipated is equivalent to the power dissipated.

We know,

Power = V²/R  or

Power = I²R

where, V is the potential difference between the ends

            I is the current supplied.

Therefore, total speed at which electrical power is consumed by the two resistors are V²/R  or I²R.
