Answer:
The salinity will decrese beacause of the salinity being desolved by more water
Explanation:
the ice will melt makeing there be more water and the salt will desolove
Answer:
The length of the bridge during the hottest part of summer is
Explanation:
From the question we are told that
The length of the steel bridge is
The temperature for this length is
The temperature at summer
The coefficient of linear expansion is
Generally the change in length of the steel bridge is mathematically represented as
Substituting value
The length of the bridge in summer is mathematically evaluated as
Substituting values
For the purpose of the exercise, we can assume that the Earth is at perihelion (closest point to the Sun) on December 21st (in reality, it happens around January 4th) and that the Earth is at aphelion (farthest point from the Sun) on June 21st (in reality, this happens around July 4th). The distance Earth-Sun is the following:
- Perihelion: 147.1 milion km
- Aphelion: 152.1 milion km
- Average distance: 149.6 milion km
So, we can calculate the percentage change with respect to the average distance as:
The term used for the total radiation that is reflected by a surface is albedo. It is the percent of solar energy that is being reflected from our Earth back into the space. It is a dimensionless value since it is a percentage and ranges from a value of zero (corresponds to a perfect black body where it absorbs all of the radiation) to one (corresponds to a white body where all radiation is being reflected). This term is very useful in astronomy, climatology and environmental management. The average albedo of Earth is found to range from 30 percent to 35 percent due to the clouds present in the atmosphere.
Answer:
No fans are not running
Explanation:
It is given that fan will be in cooling condition when the temperature will be 32°C
When we change 32°C to Fahrenheit then
As the given temperature is 90°F which is greater than 88.6°F so the fin will not run ,for running the fan temperature should be greater than 90°F
