Answer:
Newton's Second Law
Explanation:
Newton's second law basically states that the acceleration of a body which is produced by a net force is directly proportional to the magnitude of net force applied in the same direction.
This tells us that
F is directly proportional to a
⇒ F= ma
So we can also state from the above equation, that when we have more mass, we need more net force to accelerate it. Here, we are keeping the acceleration constant so we can surely say that force and mass varies directly.
Therefore, we have made good use of Newton's Second Law of motion to arrive at this conclusion.
Answer:
Yes, this is true. The reason is that the flower transpires and sucks the water in and distributes it as much as it can. You can also flip it upside down and hang it with petals down , allowing the liquid to enter the flower and then retaining color for longer periods of time and having more color.
Explanation:
Answer:
1255.4L
Explanation:
Given parameters:
P₁ = 928kpa
T₁ = 129°C
V₁ = 569L
P₂ = 319kpa
T₂ = 32°C
Unknown:
V₂ = ?
Solution:
The combined gas law application to this problem can help us solve it. It is mathematically expressed as;
![\frac{P_{1} V_{1} }{T_{1} } = \frac{P_{2} V_{2} }{T_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20V_%7B1%7D%20%7D%7BT_%7B1%7D%20%7D%20%20%20%3D%20%5Cfrac%7BP_%7B2%7D%20V_%7B2%7D%20%7D%7BT_%7B2%7D%20%7D)
P, V and T are pressure, volume and temperature
where 1 and 2 are initial and final states.
Now,
take the units to the appropriate ones;
kpa to atm, °C to K
P₂ = 319kpa in atm gives 3.15atm
P₁ = 928kpa gives 9.16atm
T₂ = 32°C gives 273 + 32 = 305K
T₁ = 129°C gives 129 + 273 = 402K
Input the values in the equation and solve for V₂;
![\frac{9.16 x 569}{402} = \frac{3.15 x V_{2} }{305}](https://tex.z-dn.net/?f=%5Cfrac%7B9.16%20%20x%20569%7D%7B402%7D%20%20%20%3D%20%5Cfrac%7B3.15%20x%20V_%7B2%7D%20%7D%7B305%7D)
V₂ = 1255.4L
