Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.
Explanation:
Answer:
12 m/s
Explanation:
English Translation
At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.
The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s
In Polish/Po polsku
Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako
P = Fv
P = 420 W
F = 35 N
v = ?
420 = 35v
v = (420/35) = 12 m/s

Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.
On which factors the validity of an experiment depends?
There are five components which are used in experiment: observations, questions, hypothesis, methods and results. The scientific method procedure is not only ensures that the same experiment can be repeated by other researchers, but this experiment is accepted. For example, there must have been arrange in a random way of the sample groups and proper work and care shows and the experiment is succeed.
So we can conclude that: Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.
