Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
You would pick the door with the piranhas, because the lion hasn’t eaten in two years so that lion, is hungrier than ever, and the piranha has eaten, hopefully, so that means the piranha is not very hungry so I would say you take the chance of the door with the piranha... I so hope this helps
The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected.
The labels that will show how the glucose and hormone levels will change in each mouse after they are joined by parabiosis are:
Those of db/db are:
- The glucose level: stays the same.
- The hormone level: decreases.
Those joined by parabiosis which are Wild type:
- Glucose level: stays the same
- Hormone level: decreases
<h3>What is the use of parabiosis to evaluate hormone function?</h3>
Parabiosis is known to be a useful and effective tool to examine hormone function.
This is b because it allows the exchange of long-lived molecules (such as hormones) to take place between the two joined organism. Therefore, the glucose levels of each mouse can stay the same, but the hormone levels will be altered.
