Answer:
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
The distance is clearly 1743 km and the time is:
Thus, the velocity turns out:
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
Answer: No
Can the change in cyclin concentration during mitosis be explained by the fact that the cell divides in two and thus divides the material in the cell into two smaller volumes?
Explanation: The cyclin concentration is not halved but degraded during mitosis.
There is an increase in cyclin concentrations at interphase. These changes are caused by the presence of Cyclin Dependent Kinase (CDK) complexes. CDK being a substrate of cyclin catalyses cyclin, thereby increasing its concentration. During mitosis, cyclins are destroyed, signifying the end of mitosis and cytokinesis.
Without this process, it will be impossible for the cell to exit mitosis.
To solve this problem we will use the ratio given by the amount of total charge (q) equivalent to the individual charge of each electron (e) multiplied by the total number of electrons (n) present, that is,
Here
q = Total charge
e = Electron charge
Our value of the charge is
We know that the charge in a electron is
Replacing we have then
Therefore the number of electrons needed to form a charge of -2nC is 
Answer:
Half life is 3.23 hours
Explanation:
Given
Decay rate at starting = 1160 decays per minute
Decay rate after 4 hours = 170 decays per minute
As we know know
Substituting the given values, we get -
Also
Substituting the given values we get -
hours
Answer:
Heat is a form of Energy whereas Temperature measures the degree of it.
Entropy is the degree of randomness of a system.
Explanation:
The distinction between Heat and Temperature is defined as under:
Heat:
The total energy of a substance which is associated with the motion or movement of its molecules is known as Heat.
It depends on the nature, shape, number and size of the particles in the substance.
Molecular motion, oscillation and rotation increases with the increase in
the amount of heat supply to the substance.
Temperature:
Unlike Heat, it is not a form energy but it is the degree of measurement of heat energy. or the degree of how much hot or cold a substance is.
Any change in the heat supplied will result in a corresponding change in the temperature of that substance.
It is independent of the nature and size of the particles in any substance.
Entropy:
It is quantity thermodynamic in nature which represents the unavailability or absence of thermal energy associated with any system for it to be converted into useful mechanical work.
It is also interpreted as the degree of randomness of a system. The more the entropy the more is the randomness in the molecules of the system.
