Answer:
Explanation:
The formula to be used here is that of the general gas law which is below
P₁V₁/T₁ = P₂V₂/T₂
where P₁ is the initial pressure (and can be represented as 1 atm)
V₁ is the initial volume (and can be represented as 1 cm³)
T₁ is the initial temperature (and can be represented as 1 °C = 274K)
P₂ is the final pressure (and would be 10 atm since the pressure increased 10 times)
T₂ is the final temperature (and would be 0.07°C = 273.07K since the temperature decreased 14 times; 1/14 = 0.07)
V₂ is the final volume which is unknown
Using the formula stated earlier
1 × 1/274 = 10 × V₂/273.07
1 × 1 × 273.07 = 10 × V₂ × 274
V₂ = 273.07/2740
V₂ = 0.099 ⇔ 0.1
Thus V₁:V₂ is 1:0.1
This means the volume of gas reduced 10 times (1/10) the original volume
Answer:
F=3.15 N pointing south
Explanation:
For the magnitude:
For the direction:
In the equation F=qE, both F and E are vectors while q is the module of the charge, this means that the direction of the electric field is the one that gives the direction of the force, in this case both point south
Explanation:
Plants, as a autotrophs have chlorophyll to capture light energy from sun to make starch and sugar. Then, consumers eat plants, and the sugar is transferred to higher trophic level in a form of organic food. Nevertheless, energy is lost by uneaten food, indigestible food, unabsorbed food, excretory waste (eg co2) and heat loss by respiration.
