KiRa [710]2 years ago
4 0

Explanation:

K.E = 5,000,000 KJ

MASS = 100,000,000 Kg

K.E = 1/2 MV^2

5000000 =  \frac{1}{2}  \times 100000000 \times v {}^{2}

5000000 = 50000000 \times v {}^{2}

v {}^{2}  =  \frac{5000000}{50000000}

v {}^{2}  =  \frac{5}{50}

therefore

v {}^{2}  =  \frac{1}{10}

v  =   \sqrt{0.1}

v = 0.316 m/s^2

nekit [7.7K]

Answer:

Explanation:

The correct answer is Metabolic alkalosis (D). A pH of 7.48 shows slight alkalinity, this normal concentration of Co2 in the blood ranges from 35 mmHg (millimetre Mercury) to 45 mmHg and the normal HCo3 ( Hydrogen trioxo carbonate ion) concentration ranges from 22mEq/L to 26mEq/L.

Therefor the patients pH level is high the Co2 level is normal and the HCo3 level is high. Hence, Metabolic alkalosis
