False. Velocity is a vector and is measured in m/s (in SI, anyway).
Based on the ideal gas equation, the pressure (P), volume (V) and temperature (T) corresponding to n moles of an ideal gas are related as:
PV = nRT
where R = gas constant
Under conditions of constant pressure and number of moles:
The volume is directly proportional to the pressure. Therefore, as the temperature drops the volume will also decrease.
V α T
This is also known as the Charles Law.
Answer: 20.4 miles
Explanation:
Here we need to use the equation:
Velocity = Distance/Time.
Initially we have that he can travel 30 miles in 2 hours, so the velocity is:
V = 30mi/2h = 15mph
Now, we reduce the velocity by 3 mph, so the new velocity is 15mph - 3 mph = 12mph.
Now we want to know the distance traveled in 1.7 hours with this velocity, this is.
Velocity*Time = Distance
12mi/h*1.7h = 20.4 miles
The negative charge distribution that surrounds the nucleus of an atom is due to the atom's electron cloud. As the electrons move around a molecule, it can make a certain position, for an instant, look negative when the electrons are on one side and when they are away from this side it can look positive. This can cause intermolecular attraction and is known as the London Dispersion force of attraction.
Answer:
22.5
Explanation:
its be because 20+70=90÷4 which would be 22.5
