during June , earth is 152,000,000km from the sun. how far is earth from the sun in miles
Answer:
94448421.2201
Explanation:
multiply the value in kilometers by the conversion factor '0.62137119223684'.
So, 152000 kilometers = 152000 × 0.62137119223684 = 94448.42122 miles.

Explanation:
as the temperature of a gas sample at constant pressure increases, the volume of the gas will _____ and there will be _____ gas particles in the same space. the density of a gas at constant pressure therefore _____ as the temperature increases.
Answer:
Increase
Less/low number
Lessen
Explanation:
Increase > Increase in temperature cause increase in volume.
Less/low number > As volume increases the number of particles to be adjusted in the same space will be lesser than before.
Lessen> At constant pressure as increase in temperature cause increase in volume so the density will lessen due to increase in volume. Density equation is given below.
Density = mass /volume
If volume increases density will get lowered.

How many joules of energy are required to melt 423g of water at 0°C?
Answer: hope this helps mark me BRAINLEST plz ;)
Explanation:42. Practice Problem How many joules of energy are required to vaporize 423g of water at 100oC and 1atmosphere of pressure. q = mHv m = 423 g Hv = 2260 J/gq = (423g) (2260J/g) = 955,980 J = 956 43. Table T – Heat Formulas
The amount of heat needed to melt 423 g of water at 0°C is 141282 J
The heat required to melt water can be obtained by using the following formula:
Q = mLQ is the heat required.
L is the latent heat of fusion (334 J/g)
m is the mass.
With the above formula, we can obtain the heat required to melt the water as illustrated below:
Mass of water (m) = 423 g
Latent heat of fusion (L) = 334 J/g
Heat (Q) required =?Q = mL
Q = 423 × 334
Q = 141282 JTherefore, the amount of heat needed to melt 423 g of water at 0°C is 141282 J

An electrolytic cell is a cell with a spontaneous redox reaction (option B).
What is an electrolytic cell?Electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.
An electrolytic cell converts electrical energy into chemical energy. The redox reaction in the cell occurs spontaneously and is responsible for the production of electrical energy.
Therefore, according to this question, option B is correct.

Give the correct order of apparatus (Crucible, Filter funnel, Test tube, Dropper, Spatula) to show the correct arrangement that can be used to prepare and investigate the nature of pH of a sample of onion solution.
Answer:
Is it Crucible,Test tube,Dropper,Filter funnel, Spatula
Explanation:
The laboratory apparatus is used to experiment with the chemicals and to hold them. To prepare and investigate the pH of the onion sample apparatus required are the crucible, test tube, dropper, filter funnel, and spatula.
What is pH?pH is the measurement of the hydrogen or the hydroxide ion concentration in the solution to determine the alkaline or acidic nature of the substance.
The pH of the onion solution can be determined by experimenting with the help of the laboratory apparatus and reagents. A crucible is a container that can withstand high temperatures.
A test tube is a glassware used to hold the substance or chemical in it. Similarly, a dropper is used to draw liquids. The filter funnel separates the filtrate or the solution. A spatula can be used to remove or add the substance.
Therefore, the correct order of the apparatus is the crucible, test tube, dropper, filter funnel, and spatula.

What does it mean to say that a wave is cyclic, or periodic, disturbance?
Answer:
Wave is a disturbance or energy that propagate through medium from one point to other point
So basically it is a flowing energy that flows into the medium and hence medium particles start oscillating about their mean position to and fro.
This motion of medium particles or this to and fro motion is about their mean position and this will always be cyclic or periodic motion
This means the disturbance or energy continuously flow through the medium such that it will change the position of medium particle and this will be cyclic in order
For an example
y(x,t) = Asin(kx - ωt + φ)
So here above equation of wave is a travelling wave in which displacement of medium particle from its mean position is given by "y"
Now we can see that this disturbance depends upon the sine function and it will repeat its same position after every 2 pi time interval as it is cyclic function for this value
Due to this phenomenon of repetition of its same position we can say that it is disturbance of wave is cyclic.
