The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. The last three trials involved the same procedure with a different rope tension.
The answer is:
Heat transfer.In order to heat up water there has to be a way that the heat puts energy into the water,which make is rise in temperature.
I hope this helps :D
Answer:
Tahukah kamu, mengapa motor berhenti di depan lampu merah?
karena motornya direm. Coba kalau nggak direm bisa bahaya tuh.

The number of pulse beats elapsed before the rubber ball hits the ground can be obtained when you carry out the experiment yourself. However, the pulse beat method of timing used by Galileo is not reliable because it varies from time to time.
Galileo was interested in studying how objects fall. His discovery was that all objects had the same acceleration irrespective of their mass. This observation was in direct contrast to Aristotle's assertion that the velocity of objects is proportional to their mass.
However, he used his pulse beats as timer during the experiment. This method is unreliable because the pulse beats of a person changes depending on the person's state of mind. A stop clock could have been a more reliable timer than pulse beats.

Ignoring air resistance . . .
-- Gravity adds 9.8 m/s to the speed of a falling object every second.
-- After falling for 3 sec, it's falling (3 x 9.8) = 29.4 m/s faster
than it was when it was dropped.
-- It started out with zero speed when it rolled off the top of the building,
so its speed is 29.4 m/s after 3 seconds.
-- Its average speed all the way down is
(1/2) (0 + 29.4) = 14.7 m/s .
-- After traveling for 3 sec at an average speed of 14.7 m/s,
it has traveled
(3 sec) x (14.7 m/s) = 44.1 meters .
