Answer:
8.5 ohms
Explanation:
from ohms law
V=IR
120=14.1R
divide both sides by 14.1
120/14.1=14.1R/14.1
R=8.5ohms
Answer:
Potential
Explanation:
Potential energy is the energy stored while kinetic energy is motional energy.
Potential itself means "having capacity/energy".

Answer:
Different star constellations are visible from Earth at different seasons of the year.
Explanation:
The reason the fact that we can see different constellations in the sky during different seasons on earth is the most compelling reason we travel around the sun is because if the sun travelled around the earth, certain constellations would only be visible in certain places. You’d have to travel to see certain ones.
However, you don’t have to do that because we travel around the sun, therefore travelling around other stars too.
Answer:
Explanation:
The Bernoulli equation is:
(1)
- P is pressure related to the fluid
- ρ is the density of the fluid (ρ(air)=1.23 kg/m³)
- v is the speed of the fluid
- h is the displacement from one position to the other
Now let's apply the equation (1), for our case:
(2)
here we assume that h is the same in both cases so it canceled out.
- <u>subscript 1</u> is related to the upper surface of the wings
- <u>subscript 2</u> is related to the low surface of the wings
Solving the equation for v₁ we have:
(3)
Now, we know that pressure P=F/A (force over area)
(4)
Combining (3) and (4), we can find v1.
I hope it helps you!
