Acceleration is non zero but the velocity is zero.
Answer: Option 2.
<u>Explanation:</u>
Acceleration is the speed that an object gains with in a short period of time. In the language of Mechanics, Acceleration is the change in the velocities of the objects with respect to the time. So when a ball is thrown up in the air, there will be some acceleration and there will be some speed that the ball will gain when thrown up.
Velocity is the speed of an object but in a particular direction. Velocity of an object is the rate of change of the position of the object with respect to the frame of reference of that frame. So the velocity of the ball up in the air is zero.
I believe that the answer is 7
Answer:

I feel like I can't help you with # 8 because you have covered up some of the other questions that would have helped me help answer question 8 . I might me wrong but I really not sure how to help you how!! SORRY! GOOD LUCK!! I HOPE THIS HELPS
It was important, because many fields were on the flood plains of the Nile. It was also important because the flooding of the Nile brought mineral and nutrient rich soil, which made the farming land more fertile. Without the knowledge of the flooding of the Nile, Egyptian agriculture might have been destroyed. It is still important to farmers along the edge of the Nile to this day.
A rain shadow is a dry area on the leeward side of a mountainous area (away from the wind). The mountains block the passage of rain-producing weather systems and cast a "shadow" of dryness behind them. Wind and moist air is drawn by the prevailing winds towards the top of the mountains, where it condenses and precipitates before it crosses the top. The air, without much moisture left, advances behind the mountains creating a drier side called the "rain shadow"
