The person should start to slow down but if close enough or in the intersection go threw. Otherwise come to a complete stop until the light turns green again
Answer:
The angular velocity is
Explanation:
From the question we are told that
The mass of the child is
The radius of the merry go round is
The moment of inertia of the merry go round is
The angular velocity of the merry-go round is
The position of the child from the center of the merry-go-round is
According to the law of angular momentum conservation
The initial angular momentum = final angular momentum
So
=>
Now is the initial moment of inertia of the system which is mathematically represented as
Where is the initial moment of inertia of the boy which is mathematically evaluated as
substituting values
Thus
Thus
Now
Where is the final moment of inertia of the boy which is mathematically evaluated as
substituting values
Thus
Thus
Hence
It will be positive since it will lose 3 electrons. Its in group 13 and the elements there lose 3 electrons to become stable
7.Jupiter is the largest planet in our solar system at nearly 11 times the size of Earth and 317 times its mass.
When we look at Jupiter, we're actually seeing the outermost layer of its clouds.
The Great Red Spot is a storm in Jupiter's southern hemisphere with crimson-colored clouds that spin counterclockwise at wind speeds
8. 58,232 km
The second largest planet in the solar system
Surface. As a gas giant, Saturn doesn't have a true surface. The planet is mostly swirling gases and liquids deeper down.
Saturn's rings are thought to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet,
9. Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star.
Uranus' atmosphere is mostly hydrogen and helium, with a small amount of methane and traces of water and ammonia.
As an ice giant, Uranus doesn't have a true surface. The planet is mostly swirling fluids. While a spacecraft would have nowhere to land on Uranus, it wouldn't be able to fly through its atmosphere unscathed either. The extreme pressures and temperatures would destroy a metal spacecraft.
10. 24,622 km
Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).
Neptune's atmosphere is made up mostly of hydrogen and helium with just a little bit of methane.
