Explanation:
The dimensions of a standard backpack is 30cm x 30cm x 40cm
The mass of an average student is 70 kg
We know that, the density of gold is 19.3 g/cm³.
Let m be the mass of the backpack. So,
An average student has a mass of 70 kg. If we compare the mass of student and mass of backpack, we find that the backpack is 10 times of the mass of the student.
Answer:
Heredity and DNA is the answer
Answer:
B. <em>Speed</em> is how fast an object is moving: speed = distance/time.
<em>Velocity</em> is the rate at which an object changes position: velocity = displacement/time
Explanation:
<em>Distance</em> is a <em>scalar </em>quantity. It has only <em>magnitude</em>. So, distance/time is also scalar. If you are travelling at 100 km/h, that is your speed, because you could be going in any direction.
Displacement is a <em>vector </em>quantity. It has both <em>magnitude and direction</em> So, displacement/time is also a vector. If you are travelling east at 100 km/h, that is your velocity, because you are stating both your speed and the direction
Answer:
Explanation:
Hello!
In this case, given the change in volume and pressure of the gas, it is possible for us to recall the Boyle's law as way to understand the inversely proportional relationship between pressure and volume:
Thus, when solving for the final pressure, P2, given the initial pressure and volume and the final volume, we obtain:
