Answer:
pursuing a goal
Explanation:
Since there are no answer choices provided I would say that this is an example of pursuing a goal. This is basically all of the tasks and struggles that an individual must go through in order to finally achieve a certain goal. It also involves gradually breaking barriers and pushing forward by increasing the complexity of the tasks until you are able to break through all of them to reach the end-goal that you have been striving for. Which is exactly what John has been doing in this scenario by gradually increasing his running time.
Answer:
The law which describes the behavior of gases in the Sun is Gay-Lussac's Law
Explanation:
The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;
Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;
P ∝ T
The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;
P = K·T
∴ P/T = K (Constant)
Answer:
<h2>
r = 9.27*10^-4m</h2>
Explanation:
Given the following parameters;
Tension in the wire T = 821N
wave speed of the transverse wave v = 185m/s
density of nickel = 8.9*10³kg/m³
radius of the wire = ?
Using the relationship for finding the speed of the wave to first get the linear density;
where is the linear density
Also;
= mass m/Length L
Since mass m = density * volume
Since A = area of the wire =
Given
0.024 = 8.9*10³*3.14r²
0.024 = 27.946r²
r² = 0.024/27.964
r² = 8.6*10^-7
r =√8.6*10^-7
r = 9.27*10^-4m
Radius of the wire is 9.27*10^-4m
I think this is the answer. I hope you can understand.
Assuming our "closed tube" is closed at only one end, then
<span> v = fλ = f*4L/n
</span><span> where "n" is the harmonic number. So
</span><span> L = nv / 4f = n*346m/s / 4*256Hz = n*0.38 m
</span> <span>Since the only option in your list that is an integer multiple of 0.38 m is 1.35 m
</span><span> I'd say that we're hearing the fourth harmonic.
answer is
</span><span>A. 1.35 m</span><span>
