Answer:
The rotation rate of the mercury are determined by the radar used by the scientists. The reflected beam of the radar are showed by the doppler broadening. The rotational period of the mercury on its axis are rotates slow as compared to orbital period.
Basically, the rotational period of the mercury takes 59 earth days to rotate about its axis.
Kinetic Energy = 1/2mv^2
M= mass
V=velocity
<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.
Answer: 0.4 km/h
100 m = 0.1 km
15min./60min. = 0.25 hr
so, divide the total distance (100 m) by the total time (15 min)
0.1 km/0.25 hr = 0.4
Answer:
They collide after
Explanation:
The time in which the two cars collide will be equal to the time in which they two cover the distance 'D'.
Let the cars meet after 't' time
Distance covered by toy car travelling at a constant velocity equals
Distance that the accelerating car travles in the same time 't' can be obtained from second equation of kinematics as
Now the condition dictates that
Solving the quadratic equation for 't' we get
We neglect negative value since time cannot be negative.
