Answer:
to the left.
Explanation:
We can use the equation where v is the velocity at time t and the velocity at . Since we want the acceleration we write this equation as:
Considering the <em>direction to the right as the positive one</em>, we have at , and at , so we substitute:
Where the minus sign indicates it is directed to the left.
Answer: option D. the ratio of the population of male deer is not constant.
Explanation:
The bar graph permits to compare the results for two different populations: male and female deer in a very easy visual way.
These features are remarkable:
- The polulation of male deer (blue bars) decrease from 1961 to 1971, then increase in the next 10 year, decrease in the next decade, and increase for the next two decades. So, its trend is erratic, with ups and downs.
This discards the option A, which states that the population of male deer increases each decade from 1961 to 2011.
- The population of female deer (purple or brown bars) decreases every decade.
This discards the option B. which states that when the polulation of male deer increases, the poluplation of female deer also increases.
- The populations never are equal, hence this discards the option C.
- Since, one popultion increases and decreases, while the other population only decreases, you conclude that the ratio of the population of male deer to female deer is not constant, which is the option D.

The energy found in one photon of visible light if the wavelength is 589 nm is, 3.37*10^-19J.
To find the answer, we have to know more about the energy of photon.
<h3>What is the energy of photon?</h3>
- We have the expression of energy of photon as,
where, c is the speed of light and h is the plank's constant.
- It is given in question that, the wavelength is 589 nm.
- Thus, the energy will be,
Thus, we can conclude that, the energy found in one photon of visible light if the wavelength is 589 nm is 3.37*10^-19J.

Answer:
5 sq. root 3
Explanation:
theta= 60°
=> u sin theta = 10 × sin 60
= 10× sq. root 3/2
= 5 sq. root 3
