Physics
A car is traveling clockwise around a circular racetrack of radius 1440m. When the car is at the northernmost point of the circle, it has a speed of 36 m/s and is slowing down at a rate of 1.2m/s^2. What is the direction of the velocity the car has?

Ответ:
East
Explanation:
In circular motion, the velocity of the object will always be tangential to the radius of the circle. In this case, since the car is at the northernmost point of the circular track, then it must be moving right or towards the east, no matter what the acceleration might be at that very moment or what the radius of the track is. If it's moving clockwise, then it moves right (towards the east).
Ответ:
Jovian Planets (means "similar to Jupiter") is the name given to the "gaseous giant" planets of our solar system. Although they share many similarities, they have certain differences.
For example, Jupiter and Saturn are classified as "gas giants", while Uranus and Neptune are "ice giants".
This is also due to the fact that Uranus and Neptune have higher concentrations of methane (hence its bluish color) and some heavier elements such as oxygen, carbon, nitrogen, and sulfur. On the other hand, Jupiter and Saturn tend to be orange-white in appearance due to the mixture of hydrogen that gives off a red aspect.
