they are only affected by gravity.
Answer:
Explanation:
The Bernoulli equation tells us that in a fluid , so we will apply this to <em>a point on the surface and a point on the hole</em>.
For a point on the surface (at height ) the velocity will be approximated to 0m/s since <em>we assume it barely moves</em> (unless other information is given), so we have:
For a point on the hole (at height and velocity of the fluid ) we have:
Since both constant are the same, cancelling we have:
Which means:
So the velocity of the fluid flowing through the hole will be:
plzzzz mark me brainliest if it helps you
Answer:
2.56 x 10^-9 N
Explanation:
charge on each proton, q = 1.6 x 10^-19 C
distance between the two protons, d = 3 x 10^-10 m
The formula for the force between the two charge is given by
F = 2.56 x 10^-9 N
Thus, the electrostatic force between the two charge is given by 2.56 x 10^-9 N.
Explanation:
Power = change in work/change in time
P = 600 joules/ 4 seconds
P= 150 watts
hope this helps :)
