Answer:
A .endoplasmic reticulum
Explanation:
Endoplasmic reticulum is the part of the plant cell that is responsible for the synthesis of proteins.
when we burn a paper it undergoes the combustion reaction.
The new tangential speed of the ball will be one-fourth the original speed.
Answer: Option D
<u>Explanation:</u>
Any object moves at circle path will exhibit tangential speed as the change in the direction of motion leads to the speed acting as tangent to the circular path.
So the tangential speed defines as distance covered by any object moving in a circular path within the given time interval. As the object will be covering the distance equals to circumference of circle path, then
So if we consider the length of the string as the radius of the circular path, then the original speed of the ball will be
If the radius is decreased to , then the new tangential speed will be
So, the new tangential speed will be one fourth of the original speed.
The answer to this question is false. Learning about the natural world begins with observations, primarily of cause and effect but also of any phenomenon, repeated or not.
