The velocity is 1100 kilometers per hour
Answer:
<u>The girl should leave the string a time when the ball is at a position tangent at that point of the circle passes through the location of target.</u>
Explanation:
The direction of an object moving in circular path changes endlessly with time. The direction of the object at some extent are within the direction of tangential drawn to the circle at that point,
The centripetal force on the ball becomes zero once the girl leaves the string. hence, the ball can go into the direction tangential to the circle at the point whenever she left the string.
Answer: The piezoelectric effect describes the property of certain solids to generate an electrical charge under mechanical stress. The actuating force modifies the microscopic structure of the body; dipoles are created between which a voltage builds up. And Their positive and negative charges complement each other creating two types of electricity: static electricity
Explanation:
Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
Explanation:
Rain that tends to fall in bands on earth is usually caused by : Warm, moist air rising and cooling
First, the water on earth evaporate due to sun's heat and formed cloud. Later on, this water condensed and fall again on the earth. Completing the water cycle
