Another name for these two words is "constant" and you want to have a "constant", because you want something to compare your experimental group to, to see whether data had changed or not. So you have placebos or a double- blind to compare your experimental group to it and also so you know you don't have a bias or anything in the study.
The <em>gaseous state</em> of matter does that. A gas expands to take the shape and volume of whatever you put it into.
Answer:
gamma rays < X-ray < ultraviolet ray < visible light < infrared < radio wave
Explanation:
given light form,
A) radio waves,B) infrared,C) visible light,D) ultraviolet,E) X-rays,F) gamma rays
we know,
wavelength of radio wave = 10000 Km
wavelength of infrared = 700 nanometers (nm) to 1 millimeter (mm)
wavelength of visible light = 380 to 740 nm
wavelength of ultraviolet ray = 10 nm to 400 nm
wavelength of X-ray = 0.01 to 10 nm
wavelength of gamma rays = 100 picometer
so, the order of rays.
gamma rays < X-ray < ultraviolet ray < visible light < infrared < radio wave
Answer:
50N
Explanation:
Given parameters:
Mass of the bike = 10kg
Acceleration = 5m/s²
Unknown:
Force on the bike = ?
Solution:
To solve this problem, we apply Newton's second law of motion.
Force = mass x acceleration
Force = 10 x 5 = 50N
The correct answer is A. The strands are different. Hope this helps! :)
