Answer:
The answer is 3000 NExplanation:
The amount of force can be found by using the formula
[tex]f = \frac{w}{d} \\ [/tex]
w is the workdone
d is the distance
From the question we have
[tex]f = \frac{15000}{5} \\ [/tex]
We have the final answer as
3000 NHope this helps you
Rahul was given iron filings and sulphur powder. He prepared a compound of iron sulphide by heating the components in a china dish. What would be his observation if he adds a few drops of dilute sulphuric acid into the compound?
Answer:
A gas with a rotten egg smell is evolved
Explanation:
When iron fillings and sulphur were heated in the vessel, the following chemical reaction took place;
Fe(s) + S(s) -----> FeS(s)
This is a direct combination reaction.
Subsequently, when dilute H2SO4 is added, the following reaction takes place;
FeS(s) + H2SO4(aq) ------> FeSO4(aq) + H2S(g)
He immediately observes the evolution of a gas with a rotten egg smell.
How does solubility impact the temperature?
Answer:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Double Displacement reactionA teacher performs a flame test lab experiment for various compounds. During the lab, the teacher mislabels one of the solutions. She needs to identify the unknown sample. Explain how the teacher can identify the unknown sample.
Answer: By performing the flame test
Explanation:
The flame test can be performed by the teacher to visually identify the substance in the solution. The metals give a characteristic color on burning. The heat of the flame causes the excitation of the electrons present in the metal ions this leads to release of energy along with the emission of visible wavelength of light. This visible light can be observed by human eye. For example, the copper produces the blue color in flame, barium gives green flame, and sodium gives yellow flame.
what is a true statement about the atom's nucleus?
Bromine has a higher ionization energy than chlorine
True or False
Answer:
Chlorine
Explanation:
Since chlorine is above bromine in the periodic table, following the trends of ionization energy in the periodic, the further up you go the more energy is required to ionize an atom.
The atomic mass unit is based on which element?
Carbon-12
Carbon-12 is the reference for all atomic mass calculations. An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12.

Complete and balance each of the following equations for gas evolution reactions HCl(aq)+ZnS(s)>
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
Further explanationEqualization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc. 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product 3. Select the coefficient of the substance with the most complex chemical formula equal to 1Reaction
HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)
1. give equation
aHCl(aq) + bZnS(s) ⇒ ZnCl₂(aq) + cH₂S(g)
2. make an equation
H, left=a, right=2c⇒a=2c(eq 1)
Cl, left=a, right=2⇒a=2⇒c=1(from eq 1)
Zn, left=b, right=1⇒b=1
So the equation :
2HCl(aq) + ZnS(s) ⇒ ZnCl₂(aq) + H₂S(g)

How could you test your prototype to determine the effectiveness of your spin table? What data could you collect? How many trials would you run?
Answer:
Testing prototypes is an inherent part of finalizing designs. Nobody wants to wonder why users are not utilizing an app the way it should be utilized or why they can’t seem to complete a purchase on your website. And nobody wants to rework something that’s already been shipped.
Conducting tests as early as the prototyping stage can help you avoid these unfortunate scenarios. User research with Qualaroo can help you validate your current design and uncover new areas of focus for the next iteration. Use Qualaroo to understand how people use your interface early on in the design process and evolve your prototype into a working product faster.

Josh is washing glasses with soap and water. He is afraid to carry the glasses because they are slippery. Josh could dry them with a towel to keep the glasses from being slippery.
What are glasses ?Glasses are visual eyewear that have lenses fixed in a frame that holds them in front of a person's eyes. The frame often has a bridge over the nose and arms that rest over the ears. Glasses are also known as eyeglasses or spectacles.
The term "glasses" likely originated from the word "spyglass," which was originally used to describe "a pair of eyeglasses" that had to be held up to the eyes in order to be fully effective.
Eyeglasses, often known as glasses or spectacles, are lenses that are mounted in frames and worn in front of the eyes to improve vision or to correct astigmatism, myopia, or hyperopia.
Thus, Josh could dry them with a towel to keep the glasses from being slippery.

Which of the following events must occur at point 6 in order to transform sedimentary rock into igneous rock?
A
Shifting tectonic plates push the sedimentary rock toward the poles, where it freezes and hardens into igneous rock.
B
Extreme winds and storms weather the sedimentary rock into particles, which collect in rivers and are compacted into igneous rock.
C
Rising oceans erode mountains of sedimentary rock into particles, which sink and get compacted into layers that form igneous rock.
D
Tectonic plates push against each other, driving sedimentary rock under Earth's surface, where it melts into magma and turns into igneous rock as it cools
Answer:
I belive the answer is D
