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

ial speeds? Juan and Kuri move the same distance in one revolution, but Juan completes the revolution in less time and has a higher speed. Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed. Juan moves a shorter distance in less time than Kuri, but their speeds are the same. Juan and Kuri complete one revolution in the same time, so they have the same speed.

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.

Estimate the number of times the earth will rotate on its axis during a human’s lifetime
Fudgin [204]

Here we have to calculate  the number of rotations made by earth around its own axis in the entire life time of a human being.

The average human life is 50 years .

Each year is 365.5 days

Hence 50 years =50 *365.5 days

                 =18,275 days

The earth rotates around its own axis in 23 hours 56 minutes and 4 second which is approximately equal to 24 hours or one days.

Hence one rotation takes one days.

⇒18,275 days =18,275 rotations

Hence the total number of rotations made by earth around its own axis in the life time of a average human life time will be 18,275 times

A coil of Nichrome wire is 25.0 m long. The wire has a diameter of 0.400mm and is at 20.0°C. If it carries a current of 0.500 A,
yaroslaw [1]

The power delivered to the coil is 0.5 Watts

<h3>Resistivity of a material</h3>

The formula for calculating the power delivered to it is expressed according to the equation

Power = I²R

where

I is the current

R is the resistance

Given

Current = 0.500A

Determine the resistance using the resistivity formula

R = ρL/A

Substitute the given parameters

R = 10^-6*(25)/0.002²

R = 2ohms

Substitute

Power = I²R

Power = (0.5)²(2)

Power = 0.5watts

Hence the power delivered to the coil is 0.5 Watts

strojnjashka [21]

Answer:

C)Before leaving for their trip, turn the central heating system off, along with lights and electrical household appliances.

Explanation:

Although, the other three options will also reduce their electricity bill but they do not explain why Mr. Hernandez's family got same electricity bill as last year even though this time they were not home for one and a half week. Also, A), B) and D) ideas are not reasonable.

So, the only conclusion is that even when they were on a vacation. the electrical appliances in their home were on. That's why the bill remained the same.

The idea of turning the central heating system off, along with lights and electrical household appliances before they leave for the trip will help reduce the energy usage. Also, it is reasonable.
