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
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
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.
Answer:
Explanation:
We can use Newton's Universal Law of Gravitation to solve this problem:
., where is acceleration due to gravity at the planet's surface, is gravitational constant , is the mass of the planet, and is the radius of the planet.
Since acceleration due to gravity is given as , our radius should be meters. Therefore, convert kilometers to meters:
.
Now plugging in our values, we get:
,
Solving for :
.
Answer: 245 meters
Explanation: 49 ? Meters
over over over
1 5 seconds
Cross multiply- 49 times 5 divided by 1 which equals 245
The unit conversion factors are always a power of ten. It is very easy to get different measurements quickly.
