How are amplitude modulation and frequency modulation techniques similar?
Both are used by cell phones to produce images.
Both transform electrical signals into sound waves.
Both modify the pulse of a carrier wave.
Both are used by radio stations to transmit sound.
Answer:
D. Both are used by radio stations to transmit sound
Explanation:
The main difference between both modulations is that in frequency modulation, the frequency of the carrier wave is modified as per the transmit data, while in amplitude modulation, the carrier wave is modified according to the data. because of this it can NOT be A, B, or C but it CAN be D

The amplitude modulation and frequency modulation techniques similar as , Both are used by radio stations to transmit sound.
So, option D is correct one.
What is difference between amplitude modulation and frequency modulation techniques ?The primary distinction between the two types of modulation is that , amplitude modulation modifies the carrier wave in accordance to data, frequency modulation modifies the carrier wave's frequency according to the transmit.The frequency modulation operates between 88 and 108 MHz and the amplitude modulation operates between 535 and 1705 KHz.learn about amplitude modulation

In carbon dioxide, how many grams of oxygen would there be if there are 24
grams of carbon?
a 55 g
b 73 g
c 64 g
d 88 g
Answer:
c. 64 grams
Explanation:
What is the proper combining ratio (by mass) for carbon to oxygen in the reaction that forms carbon dioxide (CO 2)? From the data given in question 1, since 64 grams of oxygen reacts with 24 grams of carbon, the ratio must be 64 to 24, which is 2.7 parts oxygen to 1 part carbon.
On the moon,When dropped from the same height Why does a flat sheet of paper fall more slowly than the same sheet when it is tightly crumpled into a ball?
Answer:
It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.

Use the balanced equation given below to solve the following problem; Calculate the volume in liters of CO produced by the reaction of 175 g of Sb2O3.
Sb2O3 + 3 C --> 2 Sb + 3 CO
40.3 L CO
7.81 L CO
20.2 L CO
13.4 L CO
Answer: 40.3 L
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} Sb_2O_3=\frac{175g}{291.5g/mol}=0.600moles[/tex]
[tex]Sb_2O_3+3C\rightarrow 2Sb+3CO[/tex]
According to stoichiometry :
1 moles of [tex]Sb_2O_3[/tex] produces = 3 moles of [tex]CO[/tex]
Thus 0.600 moles of [tex]Sb_2O_3[/tex] will produce=[tex]\frac{3}{1}\times 0.600=1.80moles[/tex] of [tex]CO[/tex]
Volume of [tex]CO=moles\times {\text {Molar volume}}=1.80moles\times 22.4L/mol=40.3L[/tex]
Thus 40.3 L of CO is produced.

A red-colored female New Hampshire Red chicken mated with a red-colored male New Hampshire Red chicken and produced golden-colored offspring. Which statement best explains how the offspring could inherit a trait not shown in the phenotypes of either parent?
Answer:
See the answer below
Explanation:
The statement that could best explain how the offspring could inherit a trait not shown in the phenotypes of either parent would be that both parents are heterozygous for the red color.
Heterozygous parents can produce offspring with a phenotype that is distinctly different from that of either parent if the recessive alleles come together during random fusion of gametes.
Let us assume that the red color (R) in the New Hampshire chicken is the dominant one and the recessive one is the golden color (r). The genotype of the heterozygous parents would be Rr.
Rr x Rr
RR Rr Rr rr
There is a probability (1/4) of producing a golden color chicken (rr), a trait that is not displayed in either of the parents.
1. How much energy (in KJ) is required to convert 50.0g of ice at – 30 ˚C to
steam at130˚C.
Answer:
How much heat energy required to convert following?
How much heat energy, in kilojoules, is required to convert 47.0 g of ice at -18.0 C to water at 25.0 C ?
Specific Heat of Ice - 2.09 j/g * c
This is how I did it and the answer is wrong...Please check and correct me
Q = m * Cice * Change in Temp
Q = (47.0 g)(2.09 J/g*c)(43) = 4222.6 J * 0.001 kj / j = 4.22 kj
Which two changes of state can occur when a substance gains thermal
energy?
Answer:
Adding enough thermal energy to a substance can cause a change of state to occur. The change of state from a solid to a liquid is called melting. When energy is added to an ice cube, the ice particles speed up as energy is absorbed. When the particles move fast enough, the solid ice melts and becomes liquid water

Explanation:
Answer:

A.homogeneous mixture
B.heterogeneous mixture
C.element
D.compound
Answer:
The correct answer is Heterogeneous mixture
Explanation:
Heterogeneous mixture are those mixture in which:
Substance is distributed in non uniform manner.
Two distinct layers are formed
Thus when water and dirt are mixed together it results in the formation of a heterogeneous mixture and after sometimes two different layers will be observed.
Hence, in the bottle there is a heterogeneous mixture of water and dirt.
