I am not suer but i thx it is...
Function. While veins usually carry deoxygenated blood from tissues back to the heart, in this case, pulmonary veins are among the few veins that carry oxygenated blood instead. Oxygenated blood from the lungs is circulated back to the heart through the pulmonary veins that drain into the left atrium.
Answer:
Explanation:
Given
COP= 60 % of carnot heat pump
For heat added directly to be as efficient as via heat pump
The weight of an object is given by:
where m is the mass and g is the gravitational acceleration.
Miguel's mass is the same on every planet (m=60 kg), the only element changing in the formula is g, the value of the gravitational acceleration, which is different for every planet. So by knowing the ratio , where g is the gravitational acceleration on Earth and is the value of the gravitational acceleration on the planet we are studying, we can calculate the ratio , where W is Miguel's weight on Earth (which we know, it is W=132 lbs), and Wx is the weight on the planet we are studying:
- For the Moon, we have
so the weight on the Moon is
- For Neptune, we have
so the weight on Neptune is
- For Mercury, we have
so the weight on Mercury is
D is the answer and also I love u
