- include the process that causes the sun to release so much energy
-The equation for the process that causes the energy. -show what is happening to all the energy coming from the sun.
-how does it affect earth and life on earth
Answer: nuclear fusion, equation:(Z + N) in a nucleus of mass M. The formula is B = (Zmp + Nmn − M)c2, All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.

A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *
A. copper
B. gold
C. silver
D. tin
Answer:
Box is made up of copper, because density is 8.96 g/cm³.
Explanation:
Given data:
Volume of box = 17.63 cm³
Mass of box = 158 g
Which metal box is this = ?
Solution:
First we will calculate the density of box then we will compare it with the density value of given metals.
d = m/v
d = 158 g/ 17.63 cm³
d = 8.96 g/cm³
The calculated density is similar to the given density value of copper thus box is made up of copper.

Answer:
It's parts can be separated using physical means.It is a pure substance.what are two things that affect gravity?
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.
Explanation:
a student collected data about how different fertilizers affect a plant growth. which type of graph should they use to show the data? PLS HELP ASAP :C worth 100 points lol
Answer:
I think they should use a bar graph
Explanation:
Because if they use a bar graph they could mark each of the different kind of fertilizer and they could easily see which one affected it the most, either good or bad, by the looking at the heights of the bars to determine your conclusion.
Hi there!

What do you think is the difference between an "open" system & a "closed" system?
Answer:
Hope it help you
Stayhomestaysafe
Plz mark my answer brainliest✍️✍️
Explanation:
There are three types of systems in thermodynamics: open, closed, and isolated. An open system can exchange both energy and matter with its surroundings. ... A closed system, on the other hand, can exchange only energy with its surroundings, not matter.

A chemist must prepare of aqueous copper(II) sulfate working solution. He'll do this by pouring out some aqueous copper(II) sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.
Answer:
380 mL
Explanation:
A chemist must prepare 925 mL of 325 mM aqueous copper(II) sulfate working solution. He'll do this by pouring out some 0.792 M aqueous copper(II) sulfate stock solution into a graduated cylinder and diluting it with distilled water. Calculate the volume in mL of the copper(II) sulfate stock solution that the chemist should pour out. Be sure your answer has the correct number of significant digits.
Step 1: Given data
Initial concentration (C₁): 0.792 MInitial volume (V₁): ?Final concentration (C₂): 325 mMFinal volume (V₂): 925 mLStep 2: Convert "C₂" to M
We will use the conversion factor 1 M = 1000 mM.
325 mM × (1 M/1000 mM) = 0.325 M
Step 3: Calculate the inital volume
We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂/C₁
V₁ = 0.325 M × 925 mL/0.792 M
V₁ = 380 mL

If a 20-N net force makes an object accelerate at 10 m/s^2, what is the mass of the object?
Answer:
The answer is 2 kgExplanation:
The mass of the object can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
where
a is the acceleration
f is the force
From the question we have
[tex]m = \frac{20}{10} \\ [/tex]
We have the final answer as

Chelsea adds a 65% acid solution to 25 milliliters of a solution that is 30% acid. How much of the 65%
acid solution should be added to create a solution that is 40% acid?
Answer:
10 ml
Explanation:
The concentration of the acid solution Chelsea adds to the 25 milliliters of 30% acid solution = 65%
The concentration of the acid solution Chelsea requires = 40%
The volume, X, of the 65% acid solution required is given as follows;
65% × X + 30% × 25 = 40% × (25 + X)
As fractions, we have;
0.65 × X + 0.3 × 25 = 0.4 × (25 + X)
0.65·X + 7.5 = 10 + 0.4·X
0.65·X - 0.4·X = 10 - 7.5
0.25·X = 2.5
X = 2.5/0.25 = 10
X = 10 ml
The volume of the 65% acid that should be added to create a solution that is 40% acid = 10 ml.

5. What is a hypothesis and how is it used?
Answer: a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
A hypothesis is used in an experiment to define the relationship between two variables. The purpose of a hypothesis is to find the answer to a question. A formalized hypothesis will force us to think about what results we should look for in an experiment. The first variable is called the independent variable

state two advantages of parallel over series connection in table form?
Advantages of parallel combination over series combination are:
1) In parallel combination each appliance gets the full voltage.
2) If one appliance is switched on/of others are not affected.
3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.
4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.
choose what you like!
Note that there are also some disadvantages to using parallel connections over series connections, such as increased complexity in wiring and the need for additional safety measures when working with high voltage circuits. The choice between series and parallel connections depends on the specific requirements of the circuit and the devices being used.

Answer:
Your friend gave the better response
Explanation:
Formula for density:
Density = mass/volume
p = m/v
Let's substitute the given values into the equation:
p = m/v
p = 23.2/8.593
Solve:
p = 23.2/8.593
p = 2.69987198883
2.69987198883 grams per volume
Notice that 2.69987198883 is the exact answer. Your answer is 2.67, which is inaccurate, even if rounded. If you were to round the exact answer to the nearest hundredth, it would be 2.70 which is not 2.67.
Therefore, your friend gave the better response because it is the correct answer.
density equals mass over volume
23.2/8.593 = 2.69 g/mL

If a sample of copper is 215g, how many moles of copper atoms are in the sample?
Answer:
3.38 moles.
Explanation:
The following data were obtained from the question:
Mass of copper (Cu) = 215 g
Number of mole of copper (Cu) =...?
The number of mole of copper (Cu) in 215 g can be obtained as follow:
Mass of copper (Cu) = 215 g
Molar mass of copper (Cu) = 63.55 g/mol
Number of mole of copper (Cu) =...?
Mole = mass /Molar mass
Mole of Cu = 215/63.55
Mole of Cu = 3.38 moles
Therefore, 3.38 moles of copper (Cu) is present in the sample.
