Conduction works by transferring heat from one molecule to another through a substance. This occurs due to the readiness of the substance to allow molecules to move. A heated molecule moves and shakes rapidly, and some of its heat energy is passed to molecules around it.
Answer:
c
Explanation:
London dispersion forces are weak intermolecular forces and are considered van der Waals forces. Temporary dipoles can occur in non-polar molecules when the electrons that constantly orbit the nucleus occupy a similar location by chance.
Answer: Your code returns a number of 99.123456789 +0.00455679
Ok, you must see where the error starts to affect your number.
In this case, is in the third decimal.
So you will write 99.123 +- 0.004 da da da.
But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.
in the error, after the 4 comes a 5, so it rounds up.
So the final presentation will be 99.123 +- 0.005
you are discarding all the other decimals because the error "domains" them.
Answer:
4.71m/s
Explanation:
Given parameters:
Distance covered = 40.5m
Time taken = 8.6s
Unknown:
Speed = ?
Solution:
The speed of Samantha is the distance divided by the time taken.
Speed =
Now insert the parameters;
Speed = = 4.71m/s
Answer:
Amy's average speed is equal to Chris's average speed.
Explanation:
Average speed is the ratio of total distance and total time interval
So here for Amy we know that
now the average speed of Amy is given as
Similarly for Chris we will have
average speed =
so correct answer is
Amy's average speed is equal to Chris's average speed.
