Juan and Kuri are on a carousel. Juan is closer to the center of the carousel than Kuri. Which statement describes their tangent
Licemer1 [7]

Answer:

Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.

Explanation:

Since Juan is closer to the center and Kuri is away from the center so we can say that Juan will move smaller distance in one complete revolution

As we know that the distance moved in one revolution is given as

d = 2\pi r

also the time period of revolution for both will remain same as they move with the time period of carousel

Now we can say that the speed is given as

v = \frac{2\pi r}{T}

so Juan will have less tangential speed. so correct answer will be

Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.

Imagine that heike onnes cooled mercury down to absolute zero and there was still resistance. would he have discovered supercond
likoan [24]

No, because superconductivity cannot occur if there is resistance

In addition to explaining electrical resistance, equilibrium distance theory also foretells the existence of superconductivity. According to its postulates, electrical resistivity decreases with distance from the equilibrium. There is only superconductivity at zero distance, with no resistance

<h3>What is Superconductivity ?</h3>

The ability of some materials to transmit electric current with virtually little resistance is known as superconductivity.

  • This ability has intriguing and maybe beneficial ramifications. Low temperatures are necessary for a material to exhibit superconductor behaviour. H. K. made the initial discovery of superconductivity in 1911.
  • Aluminum, magnesium diboride, niobium, copper oxide, yttrium barium, and iron pnictides are a few well-known examples of superconductors.

What is the mass of a falling rock if it produces a force of 50 N?
Rasek [7]
××F=m \times a×

50N is your force and the acceleration is -9.8m/s^2 due to gravity. 

So, you just plug that in. 

50 N=m\times-9.8m/s^2\\&#10;\frac{50}{-9.8}=m\\&#10;m=-5.102

BUT you know that mass cannot be negative, so you just disregard the negative sign and the mass of the rock is 5.102 grams.
