A 2-kg wood block is pulled by a string across a rough horizontal floor. The string exerts a tension force of 30 n on the block at an angle of 20º above the horizontal. The block moves at constant speed. If the block is pulled for a distance of 3. 0 m, how much work is done by the tension force?.
Only the horizontal component (the component parallel to the floor) of tension does work on the block. This parallel component has magnitude
(30 N) cos(20°) ≈ 28.2 N
and acts over a distance of 3.0 m, so it performs

The fifth term of a geometric sequence is 781. 25. Each term of the sequence is of the value of the following term. Which recursive formula represents the situation?.
Answer: an = 5an-1
Explanation: Given fifth term of a geometric sequence is 781.25.
a5 = 781
Also, each previous term is 1/5 of the value of the current term.
Therefore, common ratio would be 5.
But we just need to find the recursive formula .
Recursive formula of a geometric sequence is given by
Plugging value of r in above formula, we get
Therefore, recursive formula would be represents the situation.
The recursive formula that represents the situation is: [tex]t_n = a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex].
What is recursive formula?A recursive formula is one that defines any term in a sequence in terms of the term(s) before it.
Let the first term of the geometric sequence be 'a' and the common ratio be 'r'.
We are given that the fifth term is 781.25, so we can write:
a * [tex]r^4[/tex] = 781.25
We also know that each term is the value of the following term, so we can write the recursive formula:
t_n = r * t_(n-1)
Where t_n is the nth term of the sequence and t_(n-1) is the previous term.
To express the recursive formula in terms of 'a' and 'r', we can use the formula for the nth term of a geometric sequence:
[tex]t_n = a * r^{(n-1)[/tex]
Substituting the recursive formula, we get:
[tex]r * t_{(n-1)} = a * r^{(n-1)[/tex]
Dividing both sides by r^(n-1), we get:
[tex]t_{(n-1)} = a * r^{(n-2)[/tex]
So the recursive formula in terms of 'a' and 'r' is:
t_n = r * t_(n-1)
[tex]= r * (a * r^{(n-2)})\\\\= a * r^{(n-1)[/tex]
Now we can substitute the value of the fifth term (781.25) to solve for 'a' and 'r':
a * [tex]r^4[/tex] = 781.25
Dividing both sides by a, we get:
[tex]r^4[/tex]= 781.25/a
Taking the fourth root of both sides, we get:
r = [tex](781.25/a)^{(1/4)[/tex]
Substituting this value of 'r' into the recursive formula, we get:
[tex]t_n = a * ((781.25/a)^{(1/4)}){^(n-1)}\\\\= a^{(3/4)} * 781.25^{(1/4)} * n^{(1/4)}[/tex]
Therefore, the recursive formula that represents the situation is:
t_n = a^(3/4) * 781.25^(1/4) * n^(1/4)

How to make hydroxyquinoline at home with grapefruit and lemon.
Hydroxyquinoline CANNOT be made from grapefruit and lemon because it can only be synthesized and is not a natural compound.
With this in mind, we can see that hydroxyquinoline is usually used to salve the effects of a freshly cut cow udder as it is applied to soothe skin.
Furthermore, it can be chemically gotten when glycerol is mixed with 2-aminophenol alongside with sulphuric acid and this cannot be gotten from grapefruit and lemon.

Please select the word from the list that best fits the definition the biological capability to bear children.
Answer:
Edge says Fecundity
Explanation:
Fecundity is the biological capacity of an organism to conceive a child - in conjunction with another organism. For this to occur it is necessary that the man and the woman be fertile, that is, they have fertility. A person's fertility is measured by the number of ovules / seeds that can be fertilized. After fertilization, the fetus grows in the gestational process and becomes a baby.
The correct word from the list that best fits the definition of the biological capability to bear children is fecundity. The correct option is E.
What is childbearing?Women can theoretically become pregnant and give birth from puberty, when they begin having periods, to menopause, when they cease having them. The reproductive years of the average woman last from 12 to 51 years.
The biological ability of one organism to conceive a child in collaboration with another creature is known as fecundity. Both the man and the woman must be fertile, or have fertility, for this to happen.
The quantity of ovules or seeds that can be fertilized is used to determine a person's fertility. The fetus develops during the gestational period after conception to become a baby.
Therefore, the correct option is E. Fecundity.

What is the frequency of a sound source that produces the same wavelength in 20∘c air?.
Based on the standard formula and data in the question, the frequency of a sound source that produces the same wavelength in 20∘c air is "115.87Hz."
What is the frequency of a sound source?The frequency of a sound source is the quantity of waves that move through a point per unit of time.
Typically, a sound wave arises from a source vibrating at a frequency f, propagates at v, and has a wavelength λ.
Therefore, in this case, we have
Velocity (v) of sound in air = 343 m/s
Wavelength (λ) = 2.96 m
Frequency (f) =?
f = v ÷ λ
f = 3.43m/s ÷ 2.96m
=> 115.87Hz
Hence, in this case, it is concluded that the correct answer is 115.87Hz.

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expenses. The disposal value at the end of the estimated 10-year life is $3,000. Ignoring income taxes, the payback period is:.
Answer:
C. 4.29 years
Explanation:
The computation of the payback period is shown below:
Payback period = Initial investment of the equipment ÷ Cash flows
where,
Initial investment = $30,000
And, the cash flows is
= $8,500 - $1,500
= $7,000
So the payback period is
= $30,000 ÷ $7,000
= 4.29 years
By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

A mixture of iron, salt, and sand can be separated using a magnet, water, a filter, and a hot plate. This separation _____.
Answer:
i think mixture
Explanation:
sorry if it wrong(tried my best)
Answer:
This is an example of a mixture that can be separated with simple separation techniques based on the physical properties of the mixtures. Magnetism, and filtration and evaporation
Iron is a magnetic material, but salt and sand are not, therefore, the iron can be separated from the mixture with the use of a magnet.
Salt and sand are mixable. Salt is soluble in water, but sand is not. Therefore by adding the sand and salt to water, the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through while restricting the sand.
The sand would be removed by the filter paper, while the solution passes through.
The salt solution and some sand residues are placed in an evaporating dish and heated at low temperatures. The water from the solution evaporates, leaving the salt behind.
Bob plants some seeds in a small cup. He puts the cup in the light and waters the soil every day. After 4 days, the seedlings emerge from the soil. What can bob conclude?.
What Bob can conclude after 4 days when the seedlings emerged from the soil is that;
The seedlings exerted an upward pushing force on the soil.
Since he planted some seeds in a cup of soil and puts water and light daily into it, it means that the seedling is supposed to germinate and begin to grow.
However, we are told that after 4 days, the seedlings emerged from the soil. What this means is that the seedlings didn't germinate and as such they instead forced their way up the soil with an upward pushing force.

Which correctly lists the three features shown in the photo? folds, strike-slip faults, and anticlines anticlines, synclines, and folds synclines, normal faults, and strike-slip faults normal faults, folds, and anticlines.
Anthe answer is A
Explanation:
The correct list of the three features shown in the photo are folds, strike-slip faults, and anticlines. The correct option is A.
What are folds?On a geological timescale, modern folds are those that first appeared in the Tertiary Period (between 65 million and 2.5 million years ago). Geological formations known as faults are the result of internal forces that are inclined or vertical (top-down).
The transcurrent fault, which is also known as a horizontal fault, develops when there is movement in the horizontal plane between two blocks.
It is more prevalent in regions where two tectonic plates converge since these zones also experience horizontal movement. When two or more of the tectonic plates of Earth are forced together, fold mountains are formed.
Therefore, the correct option is A, folds, strike-slip faults, and anticlines.
