Important thing when making a lava lamp are the two liquids with different density so that it would not mix and that it would expand when heated. The movement of the orange liquid is called convection. if you will not heat the orange one, it till just stay on the stop and not go under tha water.
Answer:
The rate of the boat in still water is 44 mph and the rate of the current is 4 mph
Explanation:
x = the rate of the boat in still water
y = the rate of the current.
Distance travelled = 120 mi
Time taken upstream = 3 hr
Time taken downstream = 2.5 hr
Speed = Distance / Time
Speed upstream
![\frac{120}{3}=x-y\\\Rightarrow 40=x-y](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B3%7D%3Dx-y%5C%5C%5CRightarrow%2040%3Dx-y)
Speed downstream
![\frac{120}{2.5}=x+y\\\Rightarrow 48=x+y](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B2.5%7D%3Dx%2By%5C%5C%5CRightarrow%2048%3Dx%2By)
Adding both the equations
![48+40=x-y+x+y\\\Rightarrow 88=2x\\\Rightarrow 44=x](https://tex.z-dn.net/?f=48%2B40%3Dx-y%2Bx%2By%5C%5C%5CRightarrow%2088%3D2x%5C%5C%5CRightarrow%2044%3Dx)
![40=44-y\\\Rightarrow 40-44=-y\\\Rightarrow y=4](https://tex.z-dn.net/?f=40%3D44-y%5C%5C%5CRightarrow%2040-44%3D-y%5C%5C%5CRightarrow%20y%3D4)
The rate of the boat in still water is <u>44 mph</u> and the rate of the current is <u>4 mph</u>
Answer:
The answer should be <u>WORK </u>
<em>(Hope this Helps)</em>
Explanation:
work is equal to the product of force and distance.
W=F*S
W=Work
F=Force applied
S=Distance
Light waves can be from any color, depends on what it is bouncing no or reflecting off of.
