For this case we have the following measures in the international system:
- <em>For the length:
</em>
It is a unit that is used to measure the length of any object: Meter.
The mass in the international system is denoted by: kilogram. It is used to have an approximate idea of the weight of objects.
The measure in the international system is: Seconds. It is used to know how much time elapses in an event to be studied.
- <em>For the temperature:
</em>
The measure in the international system is: Kelvin. It is used to get an idea of how cold or hot an object, process, place, person can be.
Answer:
Length: meter
Mass: Kilogram
Time: Second
Temperature: Kelvin
6. B. 4 electrons

8. D. 3
9. Nitrogen gas is almost 80% of the atmosphere
10. Diatomic molecules compose 2 atoms
Complete Question
The complete question is shown on the first uploaded image
Answer:
The total pressure is
The temperature at the bottom is
Explanation:
From the question we are told that
The length of the glass tube is
The length of water rise at the bottom of the lake
The depth of the lake is
The air temperature is
The atmospheric pressure is
The density of water is
The total pressure at the bottom of the lake is mathematically represented as
substituting values
According to ideal gas law
At the surface the glass tube not covered by water at surface
Where is the volume of
At the bottom of the lake
Where is the volume of the glass tube not covered by water at bottom
and i the temperature at the bottom
So the ratio between the temperature at the surface to the temperature at the bottom is mathematically represented as
substituting values
=>
It is bracking down because of all the pollutoin
The forces on the car are:
-- 7,500 N forward, from the engine
-- 5,000 N backwards, from air resistance
-- 2,200 N backwards, from road friction
The net force on the car is (+7,500 - 5,000 - 2,200) = 300 N forward .
Newton said: Force = (mass) x (acceleration)
Divide each side by (mass) :
Acceleration = (force) / (mass)
Acceleration = (300 N) / (1,200 kg) = <u>0.25 m/s² forward</u>.
Notice the big red herring at the beginning of the question:
It's nice to know that the vehicle starts out traveling at 50 km/hr,
but in order to answer this question, we honestly don't care !
