Answer:
1800V
Explanation:
Given parameters:
Power in the resistor = 180W
Current = 0.1A
Unknown:
Potential difference = ?
Solution:
The power in a circuit is given as:
P = I V
P is the power
I is the current
V is the potential difference
Now insert the parameters and solve for V;
180 = 0.1 x V
V = 1800V

Darryl finds a bottle of what looks like clear water, with dirt settled at the bottom. When he shakes the bottle, the water gets dirty. Which term best describes the matter in the bottle?
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.

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.

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

What is responsible for the blue sky?
Answer:
The blue color of the sky is caused by the scattering of sunlight off the molecules of the atmosphere.
Explanation:
Answer:
sun shine
Explanation:
Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time

What are half-reactions for a galvanic cell with Zn and Mg electrodes?The emf of a half-cell, with respect to the standard hydrogen electrode, is called the reduction potential. The emf for the Mg-Zn cell described would be: E=Eo(red) (Zn) - Eo(red) (Mg) = -0.76 - (-2.38) = 1.62V if the solutions are 1.0 M.
What are the half-reactions of a galvanic cell?A half-cell reaction is either an oxidation reaction in which electrons are lost or a reduction reaction in which electrons are gained. The reactions occur in an electrochemical cell in which the electrons are lost at the anode through oxidation and consumed at the cathode where the reduction occurs.

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.

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

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.
