A hypothesis must be TESTABLE in order to be termed a scientific hypothesis.

The zeroth law of thermodynamics states that if two thermodynamic systems each are in thermal equilibrium with a third, then they are in thermal equilibrium with each other.
Answer:
0.79 cm
Explanation:
The computation is shown below:-
Particle acceleration is
![a = \frac{qE}{m}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7BqE%7D%7Bm%7D)
We will take d which indicates distance as from the negative plate, so the travel by proton is 0.800 cm - d at the same time
![d = \frac{1}{2} a_et^2\\\\0.800 cm - d = \frac{1}{2} a_pt^2\\\\\frac{d}{0.800 cm - d} = \frac{a_e}{a_p} \\\\\frac{d}{0.800 cm - d} = \frac{m_p}{m_e} \\\\\frac{d}{0.800 cm - d} = \frac{1836m_e}{m_e}](https://tex.z-dn.net/?f=d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20a_et%5E2%5C%5C%5C%5C0.800%20cm%20-%20d%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20a_pt%5E2%5C%5C%5C%5C%5Cfrac%7Bd%7D%7B0.800%20cm%20-%20d%7D%20%3D%20%5Cfrac%7Ba_e%7D%7Ba_p%7D%20%5C%5C%5C%5C%5Cfrac%7Bd%7D%7B0.800%20cm%20-%20d%7D%20%3D%20%5Cfrac%7Bm_p%7D%7Bm_e%7D%20%5C%5C%5C%5C%5Cfrac%7Bd%7D%7B0.800%20cm%20-%20d%7D%20%3D%20%5Cfrac%7B1836m_e%7D%7Bm_e%7D)
After solving the equation we will get 0.79 cm from the negative plate.
Therefore it is 0.79 cm far from the negative pate i.e the point at which the electron and proton pass each other
Answer:
Distance per unit time
Explanation:
Speed is the rate at which someone or something is able to move or operate.
A microwaveable cup-of-soup package needs to be constructed in the shape of a cylinder to hold 600 cubic centimeters of soup. The sides and bottom of the container will be made of styrofoam costing 0.02 cents per square centimeter. The top will be made of glued paper, costing 0.05 cents per square centimeter. Find the dimensions for the package that will minimize production costs.
h: height of the cylinder, r: radius of the cylinder
The volume of a cylinder: V=πr2h
Area of the sides: A=2πrh
Area of the top/bottom: A=πr2
The cost of packaging, C=2πrh*0.02+ πr^2*0.02+ πr^2*0.05 subject to the constraint πr^2h=600
C=πr(0.04h+.07r) and the constraint implies h=600/ πr^2
So C=πr(24/πr^2+.07r)=24/r+.07πr^2
C'=-24/r^2+0.14πr=0
r^3=24/0.14π r=3.79 cm
h=600/πr^2=13.3 cm
C=π*3.79*(0.04*13.3+.07*3.79)=9.48cents
C''=0.14π+48/r^3>0 for all r>=0 so our solution is indeed a minimum.
