In the formation of mountain ranges and all other landforms, there is always a cycle involved. As one mountain comes up, another land gets pushed down into the hot mantle, where the rock will melt. Due to convection currents, the tectonic plates move and their boundaries cause them to interact with each other. As mountain ranges are formed, other land gets pushed up forming what we know are mountains, with rising magma from other parts of the world solidifying creating new rock to fill the empty space.
There is one major difference between electromagnetic waves and mechanical waves. Electromagnetic waves can travel through space and medium. Mechanical waves needs matter to transfer.
Answer:
Explanation:
Using Hooke's law,
F = -kx
Where,
F = force of the mass
k = spring constant/stiffness
x = length of the spring
Given:
F1 = m1*a
= 4.1 * 9.81
= 40.221 N
F2 = m2*a
= 1.5 * 9.81
= 14.715 N
x1 = 2.9 cm
F1/x1 = F2/x2
Therefore,
x2 = (14.715 * 2.9)/40.221
= 1.06 cm.
Answer:
a. 340.13 m/s b. 680.26 m/s c. our wavelength doubles
Explanation:
a. speed of wave, v = fλ were f = frequency = 301 Hz and λ = wavelength = 1.13 m.
v = fλ = 301 Hz × 1.13 m = 340.13 m/s
b. If we double the frequency then f = 2 × 301 Hz = 602 Hz
v = fλ = 602 Hz × 1.13 m = 680.26 m/s
c. If the speed of the wave is still 340.13 m/s, if we cut the frequency in half, then frequency now equals f = 301 Hz/2 = 150.5 Hz.
Since v = fλ,
λ = v/f = 340.13 m/s ÷ 150.5 Hz = 2.26 m.
Since our initial wavelength λ₀ = 1.13 m,
λ/λ₀ = 2.26 m/1.13 m = 2.
So, λ = 2λ₀ our wavelength doubles
Spectrophotometry is a laboratory technique
that can be performed first to check if there is presence of arsenic mixed in
with Gatorade. In spectrophotometry, arsenic concentration will be measure in a
specific solution by calculating the amount of light absorbed by inorganic
arsenic.
Various analytical reagents are used such as molybdate reagent and variamine blue
as a chromogenic reagent where a violet colored indicates presence of arsenic.
Furthermore,
new analytical reagents has been development and proposed like vanillin-2-
amino nicotinic acid (VANA) and 2, 4-Dihydroxy benzophenone-2-amino thiophenol
(BPBT). These are used for direct non-extractive spectrophotometric determination of arsenic. The reagent
reacts with arsenic in acidic
medium to form light greenish yellow colored.
