Answer:
For generating electricity, there must be a power source present and a total circuit. In order to generate electricity from citcrus fruit circuit, it is necessary to have materials like wire, a small bulb, lemon fruit, and two metal elements. The power source in this circuit is the lemon fruit. The metals that are taken here in this experiment are zinc and copper.

Answer:
colloid
Explanation:
A colloid is a mixture in which one substance of microscopically dispersed insoluble or soluble particles is suspended throughout another substance. Some colloids are translucent because of the Tyndall effect, which is the scattering of light by particles in the colloid.
Answer:
1.31x10¹¹ g/cm³
Explanation:
The mass of the proton is equal to the mass of the neutron, which is 1.67x10⁻²⁴ g, so the mass of the alpha particle is 4*1.67x10⁻²⁴ = 6.68x10⁻²⁴ g.
1 fm = 1.0x10⁻²³ cm, thus the radius of the alpha particle is 2.3x10⁻¹² cm. If the particle is a sphere, the volume of it is:
V = (4/3)*π*r³, where r is the radius, so:
V = (4/3)*π*(2.3x10⁻¹²)³
V = 5.1x10⁻³⁵ cm³
The density of the particle is the how mass exists per unit of volume, so, it's the mass divided by the volume:
d = 6.68x10⁻²⁴/5.1x10⁻³⁵
d = 1.31x10¹¹ g/cm³
Answer:
Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water
Explanation:
How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.
There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.
A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher
Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least
