Reduce the force F ij = + (2 5 ) kN to point A(2m,3m) that acts on point B( 3m,5m) - .
Given :
Force, [tex]\vec{F}= (2\hat{i} + 5\hat{j})\ kN[/tex].
Force is acting at point A( 2 m, 3 m ) and B( 3 m, 5 m )
To Find :
The work done by force F .
Solution :
Displacement vector between point A and B is :
[tex]\vec{d} = (3-2)\hat{i} + (5-3)\hat{j}\\\\\vec{d} = \hat{i} + 2\hat{j}[/tex]
Now, we know work done is given by :
[tex]W = \vec{F}.\vec{d}\\\\W= (2\hat{i} + 5\hat{j}).(\hat{i}+\hat{2j})\\\\W = (2\times 1) +( 5\times 2) \ kJ\\\\W = 12 \ kJ[/tex]
W = 12000 J
Therefore, work done by force is 12000 J .
\o you sell them?” "Fivepence farthing for one—Twopence for two,” the Sheep replied. "Then two are cheaper than one?” Alice said in a surprised tone, taking out her purse. "Only you MUST eat them both, if you buy two,” said the Sheep. "Then I'll have ONE, please,” said Alice, as she put the money down on the counter. For she thought to herself, "They mightn't be at all nice, you know.” The Sheep took the money, and put it away in a box: then she said "I never put things into people's hands—that would never do—you must get it for yourself.” And so saying, she went off to the other end of the shop, and set the egg upright on a shelf. "I wonder WHY it wouldn't do?” thought Alice, as she groped her way among the tables and chairs, for the shop was very dark towards the end. "The egg seems to get further away the more I walk towards it. Let me see, is this a chair? Why, it's got branches, I declare! How very odd to find trees growing here!

write a paragraph on how iron and copper(separately) is manufactured, what it consists of and processes that it went through to be usable in its current form
Answer:
Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.
Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. ... Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill.

E. Sea salt
F Gasoline
i don't want to see any links
If i do you will be reported
Answer: A. Water dam
B. Coal- fired generator
C. Solar panel array
D. Nuclear power reactor
F. Gasoline
Explanation:
Water dam is a source of hydroelectrical energy as the energy produced by the high speed water currents can be used to generate electrical energy.
Coal fired generator is a source thermal energy.
Solar panel array converts the heat energy from the sun into electrical energy.
Nuclear power reactor converts the thermal energy from the radiations generated after the fusion and fission reactions of the heavy atoms in a nuclear reactor. The thermal energy is converted into electrical energy.
Gasoline is a source of thermal energy which is used to run the machine or vehicle. This way thermal energy is converted into mechanical energy.
A 25mm square cross-section bar of length 300mm carries an axial compressive
load of 50kN. Determine the stress set up in the bar and its change of length when the
load is applied. For the bar material E = 200 GN/m
^2
Answer:
The correct answer is "299.88 mm".
Explanation:
The given values are:
Length,
[tex]l_o=300 \ mm[/tex]
Load,
[tex]P=50 \ kN[/tex]
i.e.,
[tex]=50\times 10^3 \ N[/tex]
[tex]E=200 \ GN/m^2[/tex]
[tex]=2\times 10^5 \ M/mm^2[/tex]
Now,
Stress,
⇒ [tex]\sigma=\frac{P}{A}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{50\times 10^3}{25\times 25}[/tex]
⇒ [tex]=80 \ N/mm^2[/tex]
The change in length will be:
⇒ [tex]\Delta l=\frac{Pl}{AE}[/tex]
On substituting the values, we get
⇒ [tex]=\frac{50\times 10^3\times 300}{25\times 25\times 2\times 10^5}[/tex]
⇒ [tex]=\frac{15000\times 10^3}{1250\times 10^5}[/tex]
⇒ [tex]=0.12 \ mm[/tex]
hence,
⇒ [tex]L=l_o-\Delta l[/tex]
[tex]=300-0.12[/tex]
[tex]=299.88 \ mm[/tex]

How does an engine work?
Answer:
The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. ... After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
Answer:
an internal combustion engine works by combination air fuel and spark all at the right time as well as compression to cause an explosion and push the piston back down and spin the crank shaft wich goes to output

active solar heating
photoelectric heating
cell heating
passive solar heating
Answer: Active solar heating
Explanation:
Active solar heating is a design which is used for the purpose of storage of solar heat for household purposes. The solar heat is used for heat up the liquid and the energy is transferred to the interior space of the house for later use. It distributes the heat throughout the building. Passive solar heating used for heating and cooling of the building but not reliable for storage purposes. Photoelectric heating convert the incident solar heat into electrical energy. Cell heating is a technology in which the thermal energy in a cell is converted into mechanical energy and it is used in machines.

Answer:
The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.
Explanation:
Hope this helped Mark BRAINLIEST!!
The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.
What is Temperature?The degree to which an object is hot or cold is measured by its temperature.
Temperature is what we refer to when we talk about how something feels warm. We can determine how much heat or energy an object contains by measuring its temperature, which is typically expressed in degrees Fahrenheit or degrees Celsius.
The heat we feel on our hands and faces is produced by highly active molecules in a boiling cup of water that are moving very quickly throughout the liquid. The energy content of colder objects is lower. These molecules have far less activity.
Therefore, The advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.
