Answer:
d=16537m
Explanation:
The energy kinetic of the motion and the work of the friction determinate the length of the ramp
Kinetic energy
Work friction
I’ll refer to electromagnetic radiation as EMR.
Visible light is a very small subset of EMR. Many other ranges like infrared, ultraviolet, or gamma must be detected by special equipment.
EMR is what makes up light, and as we know from any high school physics class, light exhibits both particle-like properties (photoelectric effect and Compton scattering) and wave-like properties (refraction, diffraction, double-slit & single-slit experiment).
EMR can travel without a medium, like the vast emptiness of space. It can also travel with a medium. It can transmit through various materials albeit at a slower speed, like water, earth’s atmosphere, glass etc.
The propagation speed of EMR in space is 3x10^8 m/s, which is a speed unattainable by any of our current means of transportation. I would say that’s quite fast.
The claim of the study is that the average attendance at games is over 523.
Under the claim the null and alternative hypotheses are,
After the performing the test, the test yields the results that, fail to reject the null hypothesis.
As null hypothesis is fail to be rejected, then it can be concluded that there is no sufficient evidence to support the claim that the average attendance at games is over 523.
Therefore the correct answer is C: <em>There is not sufficient evidence to support the claim that the mean attendance is greater than 523.</em>
Answer:
Explanation:
Heat absorb, Q = 10 kWh
Work, W = 9 kWh
As by 1 st law of inventor
Q = W
But here, Q ≠ W , so the machine is perpetual motion machine of 1 st kind.
Answer:
<em>The volume is increased in a ratio of 64/27</em>
Explanation:
<u>The Volume of a Sphere
</u>
The volume of a sphere of radius r is given by:
If the radius was changed to r', the new volume would be:
Dividing the latter equation by the first one:
Simplifying:
Or, equivalently:
Since r':r = 4:3, thus:
The volume is increased in a ratio of 64/27
