<span>Because you are running so fast, your body produces a lot of lactate. Along with this lactate comes a hydrogen ion (H+), and you can’t have too many of these in the body because they will make the body fluids acidic. So the body “buffers” the H+ using biocarbonate (HCO3-) which produces CO2 and H2O. This raises the CO2 concentration of your blood, which is detected by receptors in the aorta and carotid arteries, and the respiratory centre of the brain, which then causes you to breath more deeply and more frequently.</span>
Cemente and Rope are two of them hope this help please mark me as brainliest.
False it never decreases, it increases or remain the same.
The cannon is 17.69 m above the ground level
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Height (h) =?
<h3>How to determine the time </h3>
We'll begin by calculating the time taken for the ball to land on the ground. This can be obtained as follow:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Time (t) =?
s = ut
622 = 333 × t
Divide both sides by 333
t = 622 / 333
t = 1.9 s
<h3>How to determine the height</h3>
The height of the cannon above the ground can be obtained as illustrated below:
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 1.9 s
- Height (h) =?
h = ½gt²
h = ½ × 9.8 × 1.9²
h = 4.9 × 3.62
h = 17.69 m

Answer:
Density = mass/volume
Volume of cube = mass/density
630g/8.94 = 70.5cm^3 (3s.f.)
Since it is a cube, its dimensions of Length x breadth x height=volume
Take 70.5 amd cube root it
![\sqrt[3]{70.4697986577)](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B70.4697986577%29)
=4.13 (3s.f)
hence , it would be 4.13 x 4.13 x 4.13 to find the volume
Hence, the answer would be 4.13cm(3s.f.)
