Explanation:
What is the value of ax the x -component of the object’s acceleration?.
Answer: B
<u>Explanation:</u>
rate x time
Chris: 40 x t = 40t
Amy: 60 x t - 2 = 60(t - 2)
Use the distance formula:
*****************************************************************************
Answer: B
<u>Explanation:</u>
x² - 8x + 19
a=1 b=-8 c=19
Use the Quadratic formula to find the solutions for x:
= 4 ± i√3
Solutions are: Factors are:
x = 4 + i√3 x - (4 + i√3) = 0
x = 4 - i√3 x - (4 - i√3) = 0
The correct answer is - D. secondary consumers.
As the snake is a predator, it falls into the category of the tertiary consumers, which means that it mostly feeds on the secondary consumers, in this case, the mice.
If the snakes are eliminated from the suggested food chain, than the main increase in numbers will be witnessed at the secondary consumers, the mice in this case, as they will lose one of their prime predators.
Since less mice will be eaten, as the owls will be their only predator, more mice will reproduce, thus their numbers will increase significantly.

The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
<h3>Balanced equation</h3>
We'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.
