I know one reason and that is because they can be bias
Answer:
Given:
Temperature, T = 3.13 K
molar mass of molecular hydrogen, m = 2.02 g/mol =
Solution:
To calculate the root mean squarer or rms speed of hydrogen molecule, we use the given formula:
where
R = rydberg's constant = 8.314 J/mol-K
Putting the values in the above formula:
Answer:
The mailbag will take 2.44 seconds to reach the ground.
Explanation:
The height of a helicopter above the ground is given by:
Height of helicopter at t = 2.10 seconds
The helicopter releases a small mailbag from the height of 29.17 m.
The initial velocity of mailbag = u = 0 m/s
Duration in which mailbag will reach the ground = T
Acceleration due to gravity = g =
Using second equation of motion ;
We have , s = 29.17
u = 0 m/s
t = T
Solving for T, we gte :
T = 2.44 seconds
The mailbag will take 2.44 seconds to reach the ground.
Answer:
The length of the pipe A is = 0.4763 m & the length of the pipe B is 0.357 m
Explanation:
Fundamental frequency = 360 Hz
Velocity = 343
(a). Length of the pipe is given by
Put all the values in above equation we get
= 0.4763 m
(b). Given that
The third harmonic of organ pipe B = the second harmonic of pipe A
Thus
Put all the values in above formula we get
0.357 m
Therefore the length of the pipe A is = 0.4763 m & the length of the pipe B is 0.357 m
