Full Question:
What is the temperature of a system in thermal equilibrium with another system made up of water and steam at one atmosphere of pressure?
A) 0°F
B) 273 K
C) 0 K
D) 100°C
E) 273°C
Answer:
The correction Option is D) 100°C
Explanation:
The temperature above is referred to as the critical point.
it is the highest temperature and pressure at which water (which has three phases - liquid, solid, and gas) can exist in vapor/liquid equilibrium. If the temperature goes higher than 100 degrees celsius, it cannot remain is liquid form regardless of what the pressure is at that point.
There is also a condition under which water can exist in its three forms: that is
- Ice (solid)
- Liquid (fluid)
- Gas (vapor)
That state is called <em>triple point. </em>The conditions necessary for that to occur are:
- 273.1600 K (0.0100 °C; 32.0180 °F) as temperature and
- 611.657 pascals (6.11657 mbar; 0.00603659 atm) as pressure

Answer:
E) a billion times brighter
Explanation:
- <u>The sun is a star, which is about billion times brighter as the reflected light from any planet orbiting around it. </u>
- The brightness is based on its composition and its position from the planet. The sun happens to be the brightest star on the Earth's sky which is about 13 billion times brighter than the next brightest star.
Answer: 1960 N
Explanation:
The bear is sliding down at constant velocity: this means that its acceleration is zero, so the net force is also zero, according to Newton's second law:

There are two forces acting on the bear: its weight W, pulling downward, and the frictional force Ff, pulling upward. Therefore, the net force is given by the difference between the two forces:

From the previous equation, we find that the frictional force is equal to the weight of the bear:

The maximum current in an ac circuit is related to the rms current by:

where

is the rms current and

is the maximum current.
If we re-arrange the formula and we use

, we can find the value of the maximum current:
