I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.
Answer: The question is incomplete because the options are not given here are the options gotten from Another website.
A. Ultraviolet light detects the presence of radioactive substances.
B.Ultraviolet light shows cold areas as blue and warm areas as red.
C.Ultraviolet light causes substances to fluoresce and give off visible light.
D. Ultraviolet light transmits information to AM and FM radio receivers.
The correct option is C.
Ultraviolet light causes substances to fluoresce and give off visible light
Explanation:
This is because UV light radiates at a very short wavelengths compared to visible light which is impossible for humans to see it. Therefore , when UV light is absorbed by some particular materials, it reflect back towards the eye as visible radiation with a longer wavelength .This process is called UV-induced visible fluorescence.
A spring scale measures weight because <span>It works by Hooke's Law, which states that the force needed to extend a </span>spring<span> is proportional to the distance that </span>spring<span> is extended from its rest position. Therefore, the </span>scale<span> markings on the </span>spring<span> balance are equally spaced. A </span>spring scale<span> can</span>not measure mass<span>, only </span>weight<span>. hope that helped</span>
<u>Answer:</u>
<u>Explanation:</u>
To calculate the volume, we can use the following formula:
.
In this case,
• density = 0.798 gcm⁻³
• mass = 25 g
Substituting values into the formula:
⇒ 
⇒
Explanation:
We have,
Slit separation, d = 0.329 mm
Distance between slit and screen, D = 2.20 m
The first bright fringe is formed at a distance off 2.9 mm from the center of the pattern. We need to find the wavelength.
For double slit experiment, the fringe width is given by :
is wavelength
So, wavelength is 433 nm.
