The fulcrum is the point in any mechanical device where the moment due to weights is zero.
(Weight 1 x distance 1) - (weight 2 x distance 2) = 0
(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0
weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m
= 2.1 Kg
Answer:
<h2>1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low),</h2>
Explanation:
HCT is calculated as:
HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100
1.45 + 3.55 = 5.0 (total blood volume); 1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT ranges from 38 to 46% (some sources claim 34.9-44.5%).
*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.
Total blood volume = Packed cell volume + plasma volume.
Answer:
The polar bear is an animal which is prevalent in the arctic region of the world which is characterized by very cold icy climate.
They adapt to these climatic conditions by maintaining a body temperature of 37°C through its thick fur and tough skin. It also has an insulating fat layer (adipose tissues) which is very thick.
This insulation helps in keeping the animal very warm in extreme temperatures.
