The Paleozoic era spanned from the Cambrian to the Permian and ended with a mass extinction at the end of the Permian. Geologists are still unsure of the cause but the theories include a meteorite impact or a massive volcanic event in Siberia or a combination of both. This could be a possible cause of the melting of the late Paleozoic ice sheets.
8 km/h +6km/h =14 km/h assuming that the boat is going the same direction as the current.
The Point Guard or Playmaker is the player with the best skill with the ball and who controls the rhythm of the game.
In basketball, the playing positions are generally divided into two groups that are:
- Interiors: An interior game is called that which is developed from spaces very close to the rim (approximately 4 or 5 meters)
- Exteriors: An outside game is called that which is generated in distant rim spaces (beyond the 6.75-meter line)
Within this classification, the interior and exterior positions have been subdivided as follows:
- Outside positions: Point guard, shooting guard, and small forward.
- Inside positions: power forward and center.
The Point Guard is in charge of directing the game. Generally, he moves the ball from one court to another to get it into play as soon as possible. His functions are:
- Organize
- Direct
- Control the rhythm of the game
- Depending on the game situation
His usual playing area is the central perimeter area. This player must be characterized by:
- Good peripheral vision.
- Great ability to go indoors and outdoors, overlong and short distances.
- The great skill with the ball.
- A lot of agility of feet and hands to defend.

To solve this problem we will rely on the kinematic equations of angular motion. For this case we have that the angular velocity is equivalent to the change between the proportion and the Period.
Here,
T = Time period
= Angular velocity of the object on the ground at the Earth's equator
Now the angular acceleration of the object on the ground at the Earth's equator is
Here,
= Radial acceleration of the object on the ground at the Earth's equator
R = Radius of the Earth
Replacing,
The period of the Earth is 24Hours and the radius was previously given, then
The radial acceleration of the object on the ground at the earth's equator is
Answer:
1/4
Explanation:
Fgravity is proprtional to 1 / r^2
now double r to 2r
1 / (2r)^2 = 1/4 * 1/r^2 <======this shows the force to be reduced to 1/4 of original when the distance is doubled
