Answer: option D. 4
Reasoning:
Assuming that the time elapsed between any two consecutive dots is the same, and that the second dot marks second 1, the column with 3 dots marks second 2, and the dot right most marks second 3, the motorcycle has positive acceleration after 4 seconds.
That is because:
1) from the first dot to the second dot: the velocity the lenght of the arrow that models the velocity decrases, which means that the acceleration is negative.
2) In the nex group of dots the length of the arrow remains equal, which means that the velocity is constant and the acceleration is 0.
3) For the last dot, the length of the arrow is greater, which means that the velocity increases, and so the acceleration is positive.
Gravity constantly acts on the apple so it goes faster and faster ... in other words it accelerates.
Ignoring air resistance, its velocity increases by 9.8 meters per second every second. That is two lots of "per second" and is written:
9.8 m/s2
9.8 m/s2 is the acceleration due to gravity near the Earth's surface. Nearly everything in our lives happens near the Earth's surface, so that value gets used a lot, and is written as a little g:
g = 9.8 m/s2
The average value of g is 9.80665 m/s2, but values are different around the world, such as Calcutta at 9.78548, London at 9.81599 and Tokyo at 9.79805.
So most people just use 9.8 m/s2
<h3><u>Answer;</u></h3>
Directions
Genes provide <u>directions</u> for a cell to assemble molecules that express traits such as eye color of seed shape.
<h3><u>Explanation;</u></h3>
- <em><u>A gene is a segment of DNA on a chromosome that codes for a specific trait. It is the set of information that controls a given trait.</u></em>
- Each gene occupies a specific position on a chromosome. Genes are responsible for characteristics inherited by an individual from the parents,because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body.
