<span>The speed of water in pipe is given by:
V=0.408(Q/D^2)
V=speed
Q=flow rate
D=diameter of pipe
Hence, the speed of the water is inversely proportional to square of diameter
If the speed of water through 1-cm diameter is V
Then, speed of water through 0.5 cm diameter is
=V/[(1/2)^2)]
=V/(1/4)
=4V
Hence, compared to the speed of water in 1 cm pipe, the speed in the 1/2 cm pipe is four times.</span>
"J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup." I looped this up, hoped it helped:)
9.8ms^-2 as it is being pulled back down by gravity
Answer:
I THINK it would be False.
Answer:
the correct answer is B
Explanation:
The law of reflection states that the angles of incidence and reflection on a surface are the same, the two rays and the normal are in the same part of the surface.
In this exercise indicate that the angle between the incident and reflected ray is 10, therefore the angle with respect to the normal that is a vertical line at the point of contact of the ray must be 5
Consequently the correct answer is B
