Answer:
Explanation:
The simplest circuit has the battery in series with the resistor
V = IR
I = V/R = 1.5 / 15 = 0.10 Amps
It could be 1.5 / 150 = 0.01 A depending on how one assumes an error or not in "150hm"
Anita has to pay attention to biometrics since even the most accomplished athletes may benefit from it.Option B is correct.
<h3>What is biometrics?</h3>
Biometrics is the measurement of physiological traits that may be used to identify a person, including but not limited to fingerprint, iris pattern, and face features.
Anita is aware that she is one of her team's top basketball players. She has drawn interest from several colleges.
One has offered her the chance to collaborate with a biometrics expert once she joins the company. Since she is already a very accomplished athlete.
Anita does not believe that this is truly essential. The best piece of advice I can give Anita is to pay attention to biometrics since even the most accomplished athletes may benefit from it.
Hence,option B is correct.

Troposphere is much warmer than the Stratosphere.
<u>Explanation:</u>
- The troposphere is the last and the lowest level of the atmosphere, so it is in close contact with the Earth's surface.
- On the other hand, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface.
- So from the above discussion, the troposphere is warmer than the stratosphere.
Answer:
1) Pm₂ = 1.9 10⁴ Pa
, b) P_feet = 5.4 10⁴ Pa
, c) Pm₄ = 4.4 10⁴ Pa
Explanation:
a) Pressure can be found using Bernoulli's equation
P₁ + ½ rho v₁² + rho g y₁ = P₂ + ½ rho v₂² + rgo g y₂
The amount of blood that runs through the constant system, all the blood that reaches the brain leaves it, so we can assume that the speed of entry and exit of the total blood is the same. In this case the equation is
P₁-P₂ = rgo h (y₂-y₁)
The gauge pressure is
Pm = P₁ -P₂
Pm₂ = 1.06 10³ 9.8 1.83
Pm₂ = 19 10³ Pa
Pm₂ = 1.9 10⁴ Pa
The pressure in the heart is
Pm₁ = 246 torr (1,013 10⁵ Pa / 760 torr) = 3,279 10⁴ Pa
Therefore the gauge pressure is an order of magnitude less
Total or absolute pressure is
Pm₂ = P_heart - P_brain
P_brain = P_heart - Pm₂
P brain = 3,279 10⁴ - 1.9 10⁴
P brain = 1.4 104 Pa
b) on the feet
Pm₃ = rho g y₃
y = 2.04 m
Pm₃ = 1.06 10³ 9.8 2.04
Pm₃ = 21 10³ Pa
Pm₃ = 2.1 10⁴ Pa
Total pressure
Pm₃ = P_feet + P_heart
P_feet = Pm₃ + P_heart
P_feet = 3,279 10⁴ + 2.1 10⁴
P_feet = 5.4 10⁴ Pa
c) If you lower your head the height change is
h = 1.83 +2.04
h = 4.23 m
Pm₄ = 1.06 10³ 9.8 4.23
Pm₄ = 4.4 10⁴ Pa
