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
Hope this Helps!!!
Mam nadzieję że to pomoże!!!

<span>The scientists use data
and measurement to obtain empirical evidence. Data can be collected through
direct observation or else experimentation. Empirical measurements and data can
be gathered by using qualitative and quantitative methods. Empirical evidence
contains the recording and analyzing the data which is a central part of scientific
method.</span>
Answer:
So then we see that the final luminosity decrease by a factor of 625 so then the correct answer for this case would be:
B. Decreases by a factor of 625
Explanation:
For this case we can use the formula of luminosity in terms of the radius and the temperature given by:
Where L_i = initial luminosity, r= radius and T = temperature.
We know that we decrease the radius by a factor of 100 and the temperature increases by a factor of 2 so then the new luminosity would be:
So then we see that the final luminosity decrease by a factor of 625 so then the correct answer for this case would be:
B. Decreases by a factor of 625
