Heat because in a machine heat must come out to follow the law of conservation of energy
Answer:
h=17357.9m
Explanation:
The atmospheric pressure is just related to the weight of an arbitrary column of gas in the atmosphere above a given area. So, if you are higher in the atmosphere less gass will be over you, which means you are bearing less gas and the pressure is less.
To calculate this, you need to use the barometric formula:

Where R is the gas constant, M the molar mass of the gas, g the acceleration of gravity, T the temperature and h the height.
Furthermore, the specific gas constant is defined by:

Therefore yo can write the barometric formula as:

at the surface of the planet (h =0) the pressure is ![P_0[\tex]. The pressure at the height requested is half of that:[tex]P=\frac{P_0}{2}](https://tex.z-dn.net/?f=P_0%5B%5Ctex%5D.%20The%20pressure%20at%20the%20height%20requested%20is%20half%20of%20that%3A%3C%2Fp%3E%3Cp%3E%5Btex%5DP%3D%5Cfrac%7BP_0%7D%7B2%7D)
applying to the previuos equation:

solving for h:
h=17357.9m
Answer:
Explanation:
The 2 equations we need here are, first:
and then once we solve for the acceleration here:
Δx
Solving for acceleration:
and now we will use that in the other equation:
Δx and
36 = 16 +
Δx and
20 =
Δx and
Δx so
Δx = 50 m
Answer:

Explanation:
To solve this problem we need to apply the concept related to Angular Acceleration. We can find it through the equation

Where for definition,

The number of revolution
was given by 20 times, then


We know as well that the salad rotates 6 more times, therefore in angle measurements that is

The cook at the end stop to spin, then using our first equation,

re-arrange to solve
,


We can know find the required time,

Re-arrange to find t, and considering that 



Therefore take for the salad spinner to come to rest is 3 seconds with acceleration of 
I had the same question. I'm pretty sure it's 23 seconds. :)
