Answer:
The wavelength of this wave is 1.01 meters.
Explanation:
The variation in the pressure of helium gas, measured from its equilibrium value, is given by :
..............(1)
The general equation is given by :
...........(2)
On comparing equation (1) and (2) :
![k=6.2](https://tex.z-dn.net/?f=k%3D6.2)
Since, ![k=\dfrac{2\pi}{\lambda}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7B2%5Cpi%7D%7B%5Clambda%7D)
![\dfrac{2\pi}{\lambda}=6.2](https://tex.z-dn.net/?f=%5Cdfrac%7B2%5Cpi%7D%7B%5Clambda%7D%3D6.2)
![\lambda=1.01\ m](https://tex.z-dn.net/?f=%5Clambda%3D1.01%5C%20m)
So, the wavelength of this wave is 1.01 meters. Hence, this is the required solution.
Answer:
its constant i think

Rinse Bacon in Water Before Cooking to Reduce Shrinkage by 50 Percent. This sounds like a bizarre thing to do, but we're talking about less bacon shrinkage! Rinse your… At the end of the day, the best way to keep your bacon from shrinking when cooking is to cook it low and slow in the oven.
Answer:
a) α = 1.875 ![\frac{rad}{s^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Brad%7D%7Bs%5E%7B2%7D%20%7D)
b) t = 8 s
Explanation:
Given:
ω1 = 0 ![\frac{rad}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Brad%7D%7Bs%7D)
ω2 = 15 ![\frac{rad}{s}](https://tex.z-dn.net/?f=%5Cfrac%7Brad%7D%7Bs%7D)
theta (angular displacement) = 60 rad
*side note: you can replace regular, linear variables in kinematic equations with angular variables (must entirely replace equations with angular variables)*
a) α = ?
(ω2)^2 = (ω1)^2 + 2α(theta)
=
+ 2(α)(60)
225 = 120α
α = 1.875 ![\frac{rad}{s^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Brad%7D%7Bs%5E%7B2%7D%20%7D)
b)
α = (ω2-ω1)/t
t = (ω2-ω1)/α = (15-0)/1.875 = 8
t = 8 s
When we set something down on the ground, the kind of work that our arms doing is : negative apex
It's happen whenever we do works that are align with the force of Gravity (to the bottom)
hope this helps
