Answer:
is the current through the body of the man.
energy dissipated.
Explanation:
Given:
- time for which the current lasted,
- potential difference between the feet,
- resistance between the feet,
<u>Now, from the Ohm's law we have:</u>
is the current through the body of the man.
<u>Energy dissipated in the body:</u>
You measure the total distance the bike travels, and the total time it takes to travel that distance. You then divide the distance by the time
Answer: D) 3.2 × 10^8
Explanation: Insulators are best described as materials which are poor conductors of electricity and hence do not allow passage of electricity through them. Resistivity are hence used to describe property or characteristic of a material which does not allow the flow or passage of electric current.
In summary, materials which high resistivity values are referred to as Insulators. Conversely, those with low resistivity or high conductivity values are called conductors while those with intermediate values are named semiconductors.
In the question given above, the material with a resistivity value of 3.2 × 10^8 - - - has a very high resistivity value (320000000Ω), the other options given have very low resistivity values ; 0.0000000017, etc and are most likely to be conductors due to their excessively low resistivity values.
Planetary rings are ice crystals or particles. These particles are numerous and they are small. Jupiter, Saturn, Uranus and Neptune all have rings and are all Jovian planets.
Saturn has big and numerous rings and are visible from Earth. Jupiter's rings are almost invisible and are dusty. Uranus and Neptune have narrow rings but they are very bright and dense and have very thin dust rings in between. Neptune's rings however are more dense than Uranus' and they seem to make arcs rather than complete circles around the planet.
Gap moons are small moons that orbit within the rings. They cause gaps in the rings because of the gravity of the moons. They push through the ring particles and move them away from each other.
Moons that are further away also affect the rings through resonances. Resonances can launch waves within the rings. Resonances also causes gaps in rings when the moons push on the ring particles repeatedly.
