The awnswer is c give me brainlest!!!
Answer:
<u>According </u><u>to</u><u> the</u><u> </u><u>Given</u><u> Statement</u><u> </u>
Canon fires directly upwarda at 150m/s ( Initial speed, u )
Acceleration due to gravity is 10m/s²
Since Cannon ball reach it maximum height so its final velocity v will be 0 m/s .
Using Kinematic Equation
On substituting the value we get
➥ 0 = 150 + 10 × t
➥ 150 = 10 × t
➥ 150/10 = t
➥ 15 s = t
So, it will take 15 seconds .
Answer:
45000 atoms is the correct answer.
Explanation:
Keona donates 1 ml of blood 473.176 times.
Each ml of blood has 1.06 gm of mass in it.
So the total mass of the blood is
(1.06 gm/ml) x (473.176 ml) = 501.566 grams
Rounded to the nearest hundredth, that's 501.57 grams.
