How does the precision of measurements affect the precision of scientific calculations?
juin [17]
<span>The precision of scientific calculations is limited by the measurement that's the least precise out of all the measurements used in the calculation. When considering significant figures, the last answer should have the least significant figures out of all the measurements that entered into account and were able to be done with the most significant figures that could be directly measured. So, as more precise we are in measurements, more precise can be the final answer to a scientific calculation.</span>

natulia [17]
The correct answer is "pulse rate of 100 bpm".
During the first week after giving birth, the female body starts returning to the pre-pregnant state. These first days postpartum, the pulse rate should be relatively low and 60-70 bpm on average. Any pulse rate exceeding this could indicate a dangerous condition for the young mother, such as an infection or internal haemorrhage. Excessive perspiration and frequent voiding are normal conditions postpartum, as well as oral temperature of 99 F.

Fresh milk has several parts that a farmer can separate and sell. A farmer removed the top layer of fat from fresh milk. What pr
Ira Lisetskai [31]

Answer: The fat has a lower density than the other parts of the milk.

Explanation:

Milk is a dairy product which is produced by the mammary gland of mammals such as cow, goat, pigs and even human beings used for the nourishment of their younger ones. Milk gotten for cow is usually processed and consumed by man. It's constituents includes the following:

-> water,

-> lactose

-> fat

-> protein and

-> minerals.

The fat component of milk can be separated by simply allowing the fresh milk to stand for a period of time and the top layer of fat removed. This is possible because fat has a lower density than the other parts of the milk. In the dairy processing, when fresh milk is allowed to stand for a period of time, the fat globules would begin to rise to the surface in a phenomena called creaming.

how does the earth evlove around the sun while the moon evlolves around the earth with out those two planets colliding
ICE Princess25 [194]

Answer:

This is a rather complicated thing to explain so I'll try my best. To put it in simple term the sun has whats called a SOI (sphere of infleunce) and anything inside of this is effected by the gravity of that planet or sun in this case. The earth is inside of this sphere of influence. The earth has a constant velocity that is making it move away from the sun but since it's in the suns SOI the path in which the earth moves is changed in a way that causes it to spin around the sun. The same thing is happening with the moon. I'm not 100% sure on this but I think the reason the moon does not just fly away towards the sun is because it is closer to earth and is more effected by earths SOI. Hope this cleared things up for you.
