Use the formula:
, where P is power (watts), I is current (amperes) and V is potential difference (volts).
For the first heater:
For the second heater:
For the third heater:
Answer:
D. It has a low resistance and allows charges to move freely.
Explanation:
The high conductivity of copper allow charges to move freely without the need of too much force. The conductivity decreases with increase in resistance. Low resistance also means less heating of the conductors. This property of copper makes it ideal for use in the manufacture of electric cables and conductors for various gadgets.
If your asking about the total amount of time the sun is visible, it will be equal over the course of a year. In Nome, Alaska, it will be daylight almost 24 hours a day in the summer and be dark almost 24 hours a day in the winter. In San Diego they are much closer to the equator and will receive sunlight roughly the same amount each day all year long. In the end these times will add up to the same amount.
However if you are asking about intensity of sun light received, San Diego will get considerably more since its near the equator and its getting almost direct sunlight. In Nome, the sunlight is hitting the earth at an angle so fewer rays of light are hitting the ground per square foot.
Answer:
Explanation:
given,
density of blood = 1060 kg/m³
v₂ = 0.800 m/s
v₁ = 0.475 m/s
change in pressure calculation
using Bernoulli's equation
both are at same level
the change in pressure is equal to 219.62 Pa
I don’t see any picture sorry I wish I can help tho
