Explanation:
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
(28.2 N) (3.0 m) ≈ 85 J
of work
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 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.
A rock is projected from the edge of the top of a building with an initial velocity of 12. 2 m/s at an angle of 63° above the horizontal. The rock strikes the ground a horizontal distance of 25 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. What is the time?.
The rock travels a horizontal distance x after time t of
x = (12.2 m/s) cos(63°) t
If it hits the ground 25 m away from where it was thrown, then for some time t we have
25 m = (12.2 m/s) cos(63°) t
Solve for t :
t = (25 m) / ((12.2 m/s) cos(63°))
t ≈ 4.5 s
Which of the following about a contour line is false?.
The statement from the given options that is false about contour lines is;
Option B; Contour lines can cross.
The missing options are;
A. Contour lines form a "V" that points upstream.
B. Contour lines can cross.
C. Contour lines connect points of equal elevation.
D. Concentric contour lines may indicate a hill.
To answer the question, we need to first understand what contour lines are.
Contour lines are lines that are used on topographic maps to show elevations, landform shapes, and slope stiffness. It can also be used to show population density and average income.
An example of a contour lines are Isotherms which means lines of equal temperature.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.
Answer:
The first law describes how thermal energy is conserved but not the direction it moves.
Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).
As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.
Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.
The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant
Given data
Mass of Player one = 105kg
Mass of Player two = 93Kg
The Velocity of Player one = 8.6m/s
The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)
Applying Newton’s Second Law in Terms of Momentum because the mass is not constant
When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,
We also want to assume that the players stuck together after the collision
An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.
P = M1V1 + M2V2
P= 105*8.6+93*9.0
P = 903 +837
P = 1740 kg · m/s.

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.

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.
