Explanation: The main property of the waves is the way how they propagate or travel in medium The waves which can travel without a medium is said to travel in vacuum or air.
Viruses cannot reproduce. they instead copy themselves with the help of a host cell. a cell can reproduce and doesn’t need help from other cells
Answer:
The correct answer is 88.84 mmHg.
Explanation:
The pressure differential between the brain and the heart while standing up will be 120 - rho × g (gravity) × h, here h is the distance from the brain to the heart. The h is 40 cm or 0.4 m.
rho×g×h = 1060 kg/m³×9.8 m/s²×0.4m
= 4155 Pa
Now converting Pa to mmHg we get:
4155 Pa × 760 mmHg / 1.01325 × 10⁵ Pa
= 31.16 mmHg
Thus, the pressure in the brain now is 120 - 31.16
= 88.84 mmHg (hypotension)
Answer: 34.98
Explanation: So basically the meteor was falling at 35.00 km/s and slowed down by 0.02. 35 - 0.02 = 34.98. Period.
