Answer:
circulatory system, lymphatic system
Explanation:
I just did the assigment and got it right.
pls help 40 points!! Augie created this chart about the two kinds of waves.
A 2-column table with 3 rows titled 2 Kinds of Waves. The first column labeled Title 1 has entries the transfer energy is perpendicular to the direction of the wave motion, particles move up and down, particles move only slightly. The second column labeled Title 2 has entries the transfer direction is parallel to the direction of wave motion, particles move side to side, particles move only slightly.
Which best labels the chart?
Title 1 is “Longitudinal Waves,” and Title 2 is “Transverse Waves.”
Title 1 is “Transverse Waves,” and T
its b
i did the quiz and got it right it is b
Answer:
b

Carbon-14 has a half-life of 5715 years. It is used to determine the age of
ancient objects. If a sample today contains 0.060 mg of carbon-14, how much
carbon-14 will be present after 28,575?
The sample of Carbon-14 after 28,575 years=0.001875 mg
Further explanationGeneral formulas used in decay:
[tex]\large{\boxed{\bold{N_t=N_0(\dfrac{1}{2})^{T/t\frac{1}{2} }}}[/tex]
T = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Carbon-14 has a half-life of 5715 years, so t1/2=5715 years
A sample today contains 0.060 mg of carbon-14, so No=0.06 mg, then :
[tex]\tt Nt=0.06(\dfrac{1}{2})^{28575/5715}\\\\Nt=0.06(\dfrac{1}{2})^5\\\\Nt=0.001875~mg[/tex]
Which of the following is a simple definition of reduction?
A. the loss of electrons
B. the gain of electrons
C. an agent that oxidizes something
D. an agent that reduces something
The answer is B on Edg 2020
Answer:
B. the gain of electrons
Explanation:
An easy way to remember this concept is the pneumonic OIL RIG:
Oxidation is Loss (of electrons)
Reduction is Gain (of electrons)
Match the part of the wave to its description.

These are the correct answer your welcome ;)
Answer:
sgsgueiehéyegeysuegeteue2
Answer:
Explanation:
The answers you put are correct...
crest- A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum.
wavelength- In physics, the wavelength is the spatial period of a periodic wave the distance over which the wave's shape repeats. (how long the wave is)
trough- A trough is the opposite of a crest, so the minimum or lowest point in a cycle.
amplitude- Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
Hope this helps! Have a great day!! :D
Silver nitrate and magnesium chloride react according to the following equation:
2AgNO3(aq) + MgCl2(aq) — 2AgCl(s) + Mg(NO3)2(aq)
What volume (in ml) of 0.247M MgCl2(aq) is required to react with 63.2 mL of 0.192M AgNO3(aq)?
Answer:
V=24,3mL
Explanation:
1)n(AgNO3)=Cm*V=0.063l*0.192M=0.012
2)n(AgNO3)/2=n(MgCl2) => MgCl2=0.012/2=0.006
3)V(MgCl2)=n/Cm=0.006/0.247=0.0243L=24,3ml
