The car's velocity after 5s : 10 m/s
<h3>Further explanation</h3>
Given
velocity=v=72 km/h=20 m/s
time=t = 5 s
acceleration=a = -2 m/s²
Required
velocity after 5s
Solution
Straight motion changes with constant acceleration
vf=final velocity
vi = initial velocity
Input the value :
The car is decelerating (acceleration is negative) so that its speed decreases
Answer:
Explanation:
Hello,
In this case, for the given decomposition of phosphorous pentachloride:
As the equilibrium constant is and the initial concentration of phosphorous pentachloride is:
Hence, by writing the law of mass action equation:
We must introduce the change occurring due to the reaction extent and the concentrations at equilibrium (ICE table methodology):
Thus, solving for we obtain:
In such a way, the equilibrium concentration of phosphorous pentachloride results:
Finally, the percent decomposition is computed by:
Best regards.
Answer:
atomic, neutrons
Explanation:
the mass number of an atom is equal to the sum of the protons and neutrons in the nucleus of the atom.
Answer:750.550mL
Explanation:
V1/T1=v2/T2
V1=540mL
T1=-55°c to convert to Kelvin
273-55=218k
V2=?
T2=30°c to convert to Kelvin
273+30=303k
540/218=v2/303
Cross multiply
218v2=540×303
V2=540×303/218
V2=163620/218
V2=750.550mL
The release of O₂( oxygen) from the process of photosynthesis is what made them to be able to float.
<h3>What is Photosynthesis?</h3>
This is referred to as the process in which green plants manufacture their food in the presence of sunlight which is trapped by chlorophyll.They are known as primary producers and they use compounds such as water and carbondioxide.
The reactants mentioned above undergo series of reactions which leads to the production of glucose and oxygen is given off as a result which is the element responsible for the floating of the aspirated spinach leaf disks in this scenario.
