When an object is pushed by a force and moves in the direction of the force, work is done on the object. The amount of work equals the force times the distance (W = Fd). A small particle is pushed by a force of 2.6 × 10-4 newtons over a distance of 3.7 × 10-3 meters. How much work was done on the particle? Express the answer to the correct number of significant figures and in proper scientific notation. The force did × 10 newton-meters of work on the particle.
Explanation:
[tex]workdone = force \times distance \\ W = (2.6 \times {10}^{ - 4} ) \times (3.7 \times {10}^{ - 3} ) \\ W = 9.62 \times {10}^{ - 7} \: joules[/tex]
The formula W = Fd, where W is the amount of work done, F is the force, and d is the distance, is used to determine how much work is done on a particle when it is pushed by a force. The force and distance in this issue are 2.6 10-4 newtons and 3.7 10-3 metres, respectively.
What is the way to calculate the work done ?We add the force and distance together to determine the work done: 9.62 10-7 newton-meters are equal to W = 2.6 10-4 newtons x 3.7 10-3 metres. The response must be presented using the appropriate scientific notation and significant numbers.

The Soil conservation method in which mountain slope is cut into step is..
Answer:
Terracing.
Explanation:
Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Soil conservation can be defined as the use of various techniques so as to prevent the loss of the top most later of the soil and protecting it from degradation. Thus, the fertility of the soil is maintained.

The oxidation of an unsaturated fatty acid leads to the production of fewer ATPs than a saturated fatty acid with the same number of carbons because ____ A) the oxidation of the fatty acid stops when it reaches the double bond B) unsaturated fatty acids cannot be metabolized C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product
Answer:
C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product
Explanation:
The beta oxidation of fatty acids is the process by which long chain saturated and unsaturated fatty acids are oxidized to the two-carbon product, acetylCoA.
The beta oxudation of fatty acids occurs in four steps after which the chain length is shortened by 2 with cleavage of an acetylCoA molecule.
The first step involves the oxidation of the fatty acid with introduction of a double bond between C-2 and C-3 of the long carbon chain. This reaction produces FADH2 which donates its electrons to electron carriers in the electron transport chain tomproduce 1.5 moles of ATP. This is the case with saturated fatty acids.
However, in unsaturated fatty acids (which are less reduced than saturated fatty acids) where there is already a double bond innthe molecule, the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product.
This causes a reduction In the number of ATP produced by unsaturated fatty acids when compared to saturated fatty acids.

Which of the following best explains the age of oceanic crust and ocean-floor features?
A. Seafloor spreading
B. Continental drift
C. Subduction
D.crystallization
The answer option which best explains the age of oceanic crust and ocean-floor features is: A. Seafloor spreading.
Earth crust refers to the outermost layer (thin shell) which makes up the Earth such as igneous, metamorphic, and sedimentary rocks.
Generally, the two (2) main types of Earth crust include:
Continental crust.Oceanic crust.An oceanic crust has a thickness ranging from 5 kilometers to 10 kilometers and it comprises denser rocks such as gabbro, diabase, and basalt.
Seafloor spreading can be defined as a process which involves the formation of new oceanic crust due to volcanic activity and an upwelling of magma at mid-ocean ridges, as well as a subsequent outward movement from the ridge.
Basically, the theory of seafloor spreading can be used to explain in details how a new oceanic crust is created or formed at mid-ocean ridges.
Hence, seafloor spreading best explains the age of oceanic crust and ocean-floor features.

Why does energy spread out evenly if there's only a 21% chance that energy spreads out evenly?
Answer:
It has to do with increasing the entropy of the universe.
Explanation:
The modern definition of entropy is that it is the extent to which a system is able to disperse its energy. Energy (such as heat!) likes to spread itself out, so that as many states as possible are occupied with the least amount of energy.

Answer:
70/100 X 2000 = 1400 tonnes of iron.
Explanation:
take the percentage of iron oxide and divide with overall amount of iron oxide using 2000 tonnes of hematite ore. 1400 tonnes of iron will be produced. this is not the percentage. if you want the percentage of iron produced just divide.
70/100 x 200 = 1400 tonnes of iron
percentage of iron produced = 70/1400 x 100 = 5 % of iron produced from 70% of iron oxide in 2000 tones of hematite ore

A certain metal M forms a soluble sulfate salt M2SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 50.0mM solution of M2SO4 and the right half cell with a 5.00M solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 20.0°C.
Which electrode will be positive?
Left
Right
Answer:
Right
Explanation:
The given parameters are;
The soluble sulfate formed by the metal, M = M₂SO₄
In the galvanic cell formed by the metal M, we have;
The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M
The concentration of M₂SO₄ in the right half cell = 5.00 M
In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated
In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode
Therefore;
The electrode which will be positive is the electrode in the right half cell.
