The radius of the electron's or basically the energy level for which the electron is found orbiting the nucleus of he hydrogen atom, as the principal quantum number tells us primarily the energy level that the electron will be found, is it the 1st, 2nd, and 3rd. The other quantum numbers tells us more specifically as per the subshell of the main shell the electron is in, the spin of the electron etc.
Boyle's law gives the relationship between pressure and volume of gas.
for a fixed amount of gas, at constant temperature the pressure of gas is inversely proportional to its volume.
PV = k
where P - pressure, V - volume and k - constant
P1V1 = P2V2
where parameters for the first instance are on the left side and parameters for the second instance are on the right side.
substituting the values in the equation
1.2 atm x 1.0 L = P x 4.0 L
P = 0.3 atm
new pressure is 0.3 atm
The question is incomplete, the complete question is;
A block is pulled 0.90 m to the right in 2.5 s. What is the blocks average speed to the nearest hundredth of a m/s
Answer:
0.36 m/s to the hundredth place
Explanation:
Now let us remember the definition of speed. Speed is defined in physics as distance/time.
Here we have the distance as 0.9 m
We have the time as 2.5 s
Hence the average speed is obtained from;
Speed = 0.9/2.5 = 0.36 m/s to the hundredth place
0 1 2 3
0 and 3 is 3
1 and 2 is 3
<span>Have you ever seen a buoy on a sea before? It goes up and down, perpendicular to the direction the wave moves. What's the motion of the sea looks like? Transverse wave, not ocean waves because we're talking about particles.</span>
