The conclusion is, medium Q is most likely a solid because solids have the highest density and sound waves travel fastest in high density media.
<h3>
Effect of density on speed of sound</h3>
Sound wave is mechanical wave that requires material medium for its propagation.
A high dense medium, is a medium with closely packed molecules. Since sound wave requires material medium for its propagation, it will travel faster in a high dense medium than a less dense medium.
Thus, the speed of sound increases as the density of the medium increases.
<h3>Speed of sound in the different media</h3>
The conclusion that can be made from the speed of sound in the different media is "Medium Q is most likely a solid because solids have the highest density and sound waves travel fastest in high density media".

Answer:
The main difference between short term and long term memory is that the short term memory stores data temporarily while the long term memory stores data permanently. Moreover, the short term memory is volatile while the long term memory is nonvolatile. Memory is the component in a computer that stores data and information.
Explanation:
Answer:
The electron’s wavefunction has at least one node (i.e., at least one place in space where it goes to zero).
Explanation:
We know that the p-orbitals have nodes. A node is a region where the probability of finding an electron goes down to zero.
P orbitals are oriented along the x,y,z Cartesian axes and are known to have angular nodes along the axes.
Hence, if an electron in a hydrogen atom is in a p state, the electron’s wavefunction has at least one node
Answer:
515.22 m/s
Explanation:
Formula for root mean square velocity is SQRT (3RT/M)
Where,
R = Rydberg's constant = 8.314 Kg. m²/ s². K. mol
T = Temperature in Kelvin
M = Molar mass in Kg/mol
First calculate molar mass,
As nitrogen is diatomic molecule,
Its molar mass is
M = 2(14) = 28 g/mol
Convert unit into Kg/mol
28 g/mol x 1 Kg/1000g = 2.8x10¯² Kg/mol
Convert temperature into kelvin
T = 25 + 273 = 298K
Put all values in formula
Vrms = SQRT (3RT/M)
Vrms = SQRT (3x8.314x298/2.8x10¯²)
Vrms = SQRT (265454. 14)
Vrms = 515.22 m/s
The horizontal components, being opposite in direction, will produce a shearing effect on the tendon, leading to injury. Thus, they will be added.
As the angle of 23 is from the vertical, we calculate the horizontal component by using
Weight acting * sin(23)
And multiply it by 2 to get the total shearing force
The weight acting is 12 times their body weight. Thus:
53 * 9.81 * 12 = 6239.2 Newtons
The total force acting on the tendon:
2 * sin(23) * 6239.2
= 4,880
= 4,900 Newtons (2 significant figures)
