A) Tolerance
Tolerance is developed after using a drug repeatedly, so the body adapts to it. Because of that, people who develop a tolerance would then need to use more of that drug to get the same effect.
Anything less dense than water will float, like oil. Anything more dense than water will sink, like rock.
Acceleration=force/mass=28/(10+4)=2m/s^2
force10kg=ma=10*2
force4kg=ma=(10*2)=20
the4 kg is pushing against the 10kg block
vf=vi+at
-10=20*28/14 * t
t=30/2=15sec
i hope this can help you.
Answer:
Q = 282,000 J
Explanation:
Given that,
The mass of liquid water, m = 125 g
Temperature, T = 100°C
The latent heat of vaporization, Hv = 2258 J/g.
We need to find the amount of heat needed to vaporize 125 g of liquid water. We can find it as follows :
![Q=mH_v\\\\Q=125\ g\times 2285\ J/g\\\\Q=282250\ J](https://tex.z-dn.net/?f=Q%3DmH_v%5C%5C%5C%5CQ%3D125%5C%20g%5Ctimes%202285%5C%20J%2Fg%5C%5C%5C%5CQ%3D282250%5C%20J)
or
Q = 282,000 J
So, the required heat is 282,000 J

Here's a explanation!
Let's solve your equation step-by-step.
![4x^3=2x^-^1](https://tex.z-dn.net/?f=4x%5E3%3D2x%5E-%5E1)
![4x^3=\frac{2}{x}](https://tex.z-dn.net/?f=4x%5E3%3D%5Cfrac%7B2%7D%7Bx%7D)
Step 1: Multiply both sides by x.
![4x^4=2](https://tex.z-dn.net/?f=4x%5E4%3D2)
![\frac{4x^4}{4} =\frac{2}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%5E4%7D%7B4%7D%20%3D%5Cfrac%7B2%7D%7B4%7D)
(Divide both sides by 4).
![x^4=\frac{1}{2}](https://tex.z-dn.net/?f=x%5E4%3D%5Cfrac%7B1%7D%7B2%7D)
![x=+(\frac{1}{2} )^(^\frac{1}{4} ^)](https://tex.z-dn.net/?f=x%3D%2B%28%5Cfrac%7B1%7D%7B2%7D%20%29%5E%28%5E%5Cfrac%7B1%7D%7B4%7D%20%5E%29)
Take the root.
