Answer:
see below
Explanation:
a. 0.1886 x 12
=2.2632
This has 2 sig figures so the answer can only have 2 sig figures
2.3
b. 2.995 - 0.16685
=2.82815
The most accurate in the problem is to thousands place so our answer can only be accurate to the thousands place
2.828
c. 910 x 0.18945=172.3995
The least number of significant figures is 3 so the answer can only have 3 significant figures
172
Answer:
Therefore letter <u>C is the correct answer.</u>
Explanation:
In a projectile motion the total time in the air can be calculated using the following equation:
We analyze the y-component motion.

When the final velocity (v(f)) is equal to zero we calculate the upward time and multiplying it by 2 we find the total time in the air. So we will have:


We can see that the <u>total time is directly proportional to the angle</u>, then when <u>θ increase t increase.</u>
Therefore letter C is the correct answer.
