Answer» $\maltese \: \underline{\sf AnsWer :} \: \maltese \\$ $\dashrightarrow\:\:\sf m \propto [F]^{x} \: [V]^{y} \: [T]^{z} \\$ By adding 'k' as a proportionality constant we get : $\dashrightarrow\:\:\sf m = k \: [F]^{x} \: [V]^{y} \: [T]^{z} \\$ $\\\bullet\textsf{ Dimensions of mass (m) =\textbf{[M$^ \text1$L$^ \text0$T$^ \text0$]}} \\$ $\bullet\textsf{ Dimensions of force (F) = [M] [LT$^{ \text{-2}}$] = \textbf{[MLT$^{ \text{-2}}$]}} \\$ $\bullet\textsf{ Dimensions of velocity (V) = $\dfrac{ \text{[L]}}{ \text{[T]}}$ = \textbf{[M$^\text0$LT$^{ \text{-1}}$]}} \\$ $\bullet\textsf{ Dimensions of Time Period (T) =\textbf{[M$^ \text0$L$^ \text0$T$^ \text1$]}}\\ \\$ $\dashrightarrow\:\:\sf [M^1 L^0 T^0] = [M^1 L^1 T^{-2}]^{x} \: [M^0 L^1 T^{-1}]^{y} \: [M^0 L^0 T^1]^{z} \\$ $\dashrightarrow\:\:\sf [M^1 L^0 T^0] = [M]^{x} \: [ L]^{x + y} \: [T]^{ - 2x - y + z} \\$ Now, on COMPARING the POWERS of LHS and RHS we get : $\longrightarrow\:\:\sf x = 1 \qquad \qquad...(i)\\$ $\longrightarrow\:\:\sf x + y = 0 \\$ From equation (i) Substituting x = 1 in above equation we get : $\longrightarrow\:\:\sf 1 + y = 0 \\$ $\longrightarrow\:\:\sf y = - 1 \qquad \qquad....

If force (F). velocity (V) and time (T) are taken asfundamental units, then the dimensions of massare[AIPMT-2014](1) [F V T-](2) [F VT(3) [FV-T'(4) [F V-T]

Answer»

$\maltese \: \underline{\sf AnsWer :} \: \maltese \\$

$\dashrightarrow\:\:\sf m \propto [F]^{x} \: [V]^{y} \: [T]^{z} \\$

By adding 'k' as a proportionality constant we get :

$\dashrightarrow\:\:\sf m = k \: [F]^{x} \: [V]^{y} \: [T]^{z} \\$

$\\\bullet\textsf{ Dimensions of mass (m) =\textbf{[M$^ \text1$L$^ \text0$T$^ \text0$]}} \\$

$\bullet\textsf{ Dimensions of force (F) = [M] [LT$^{ \text{-2}}$] = \textbf{[MLT$^{ \text{-2}}$]}} \\$

$\bullet\textsf{ Dimensions of velocity (V) = $\dfrac{ \text{[L]}}{ \text{[T]}}$ = \textbf{[M$^\text0$LT$^{ \text{-1}}$]}} \\$

$\bullet\textsf{ Dimensions of Time Period (T) =\textbf{[M$^ \text0$L$^ \text0$T$^ \text1$]}}\\ \\$

$\dashrightarrow\:\:\sf [M^1 L^0 T^0] = [M^1 L^1 T^{-2}]^{x} \: [M^0 L^1 T^{-1}]^{y} \: [M^0 L^0 T^1]^{z} \\$

$\dashrightarrow\:\:\sf [M^1 L^0 T^0] = [M]^{x} \: [ L]^{x + y} \: [T]^{ - 2x - y + z} \\$

Now, on COMPARING the POWERS of LHS and RHS we get :

$\longrightarrow\:\:\sf x = 1 \qquad \qquad...(i)\\$

$\longrightarrow\:\:\sf x + y = 0 \\$

From equation (i) Substituting x = 1 in above equation we get :

$\longrightarrow\:\:\sf 1 + y = 0 \\$

$\longrightarrow\:\:\sf y = - 1 \qquad \qquad.... (ii)$

$\longrightarrow\:\:\sf - 2x - y + z = 0 \\$

From equation (i) and (ii) Substituting the VALUE of x and y in above equation:

$\longrightarrow\:\:\sf - 2(1) - ( -1 ) + z = 0 \\$

$\longrightarrow\:\:\sf - 2 + 1 + z = 0 \\$

$\longrightarrow\:\:\sf - 2 + 1 = - z\\$

$\longrightarrow\:\:\sf - 1 = - z\\$

$\longrightarrow\:\:\sf z = 1\\$

Hence, our FINAL answer will be :

$\dashrightarrow\:\: \underline{ \boxed{\frak{m = [F]^{1} \: [V]^{-1} \: [T]^{1}}}} \\$

Hence,the OPTION (4) is correct answer.

What does it mean？Q:2 why should plastics be recycled rather than incinerated or burried？Q:3 in what ways are plastics responsible for pollution？Q:4 how would you distinguish between a thermoplastic and a thermosetting plastic？PLEASE HELP ME
Answer» Answers : 1. Any substance that cannot be decomposed by the microorganism in nature into its monomers and causes harm to the environment is called a non - biodegradable substance . Plastic is a polymer that cannot be decomposed by microorganism and remains unaffected even for the period of MILLION of YEARS . Hence , these are termed non - biodegradable . 2. Plastic should be recycled rather than incinerated ( put down to ashes in incineration chambers) or burried inside soil because when burned plastic releases toxic gases and carbon DIOXIDE which causes global warming . Burying plastics will lead to increased LANDFILLING repeatedly . Thus they should be recycled into another usable form for AVOIDING any damage to the environment. 3. Plastics are non - biodegradable substance. When buried inside the soil , they do not get decomposed for over a span of millions of years causing soil pollution . They also choke the water bodies causing water pollution . Plastics are also a main source of air pollution because when burned , these release toxic gases into the environment . 4. A thermoplastic is a kind of plastic that can be molded repeatedly to another usable form whereas a thermosetting plastic is the one that once used cannot be molded again .

Burying plastics will lead to increased LANDFILLING repeatedly . Thus they should be recycled into another usable form for AVOIDING any damage to the environment.

3. Plastics are non - biodegradable substance. When buried inside the soil , they do not get decomposed for over a span of millions of years causing soil pollution . They also choke the water bodies causing water pollution . Plastics are also a main source of air pollution because when burned , these release toxic gases into the environment .

4. A thermoplastic is a kind of plastic that can be molded repeatedly to another usable form whereas a thermosetting plastic is the one that once used cannot be molded again .

38.	Middle man Ofcirculatry system
Answer» Answer: The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The circulatory system includes the lymphatic system, which circulates lymph.[1] The passage of lymph takes MUCH longer than that of blood.[2] Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. Lymph is essentially recycled excess blood plasma after it has been filtered from the interstitial fluid (between cells) and returned to the lymphatic system. The cardiovascular (from LATIN words meaning "heart" and "vessel") system comprises the blood, heart, and blood vessels.[3] The lymph, lymph nodes, and lymph vessels FORM the lymphatic system, which returns filtered blood plasma from the interstitial fluid (between cells) as lymph. The circulatory system of the blood is seen as having two components, a SYSTEMIC circulation and a pulmonary circulation.[4] While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never LEAVES the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The lymphatic system, on the other hand, is an open system providing an accessory route for excess interstitial fluid to be returned to the blood.[5] The more primitive, diploblastic animal phyla lack circulatory systems. Many diseases affect the circulatory system. This includes cardiovascular disease, affecting the cardiovascular system, and lymphatic disease affecting the lymphatic system. Cardiologists are medical professionals which specialise in the heart, and cardiothoracic surgeons specialise in operating on the heart and its surrounding areas. Vascular surgeons focus on other parts of the circulatory system.

40.	I want to use 100 to 150 SMD LEDs of 1w 3.3v in a project and light them, how can I convert 3.7v to 3.3v to use them from a single lipo battery keeping it as cheap as possible
Answer» Answer: Explanation:I keep receiving requests from the readers who seem confused with the connection details of 5mm LEds with a 3.7V Li-ion cell. The requests inspired me to write this post, hopefully it WOULD answer the many related queries. Using a Cellphone Li-ion Cell Since standard 3.7V Li-Ion cells which are normally used in cell phones are rated at around 800 to 1100mAh, are quite capable of supporting a few 5mm LEDs, and would be able to keep them illuminated for quite sometime. A normal 5mm white LED requires about 20mA current at 3.3V for getting illuminated optimally. The circuit involved for illuminating 5mm LEds through a 3.7V Li-Ion cell is actually too simple, primarily because the parameters are closely matched with each other. Here, connecting the 5mm LEDs in series wouldn't be feasible because the maximum volts from the cell is just 3.7V while even two LEDS in series would call for above 6V. Therefore the only option left is putting them in parallel. Ideally when parallel connections are involved, a series limiting RESISTOR becomes imperative with each LED in the array. This helps ensure uniform light distribution or emission from the LEDs. However it's not an absolute requirement, ESPECIALLY when the driving voltage is close to the forward voltage of the LEDs. Also taking the simplicity factor into account, a single limiting resistor may be used in such cases and therefore here too we have eliminated individual resistors. How to Connect the LEDs The circuit diagram below shows a simple configuration comprising of a 3.7V Li-ion cell, 5nos 5mm LEDs and a limiting resistor R1. The procedure shows how simply a Li-ion cell may be used for illuminating 5mm LEDs for a reasonably long period of time. Each LED is supposed to consume 20mA current, therefore 5nos would together consume around 100mA, therefore R1 may be calculated as follows: The Formula R = (Supply voltage - LEd forward voltage)/LED current = (3.7 - 3.3)/100 = 0.4/0.1 = 4 ohms. The required wattage would be 0.4 x 0.1 = 0.04W, so a 1/4 watt resistor would be more than enough. Assuming the cell to be rated at 800mAH, with 5 LEDs, the APPROXIMATE back up time available from the cell could be calculated using the following cross-multiplication. 800/100 = x/1100x = 800x = 800/100 = 8 hours ideally. However practically you would find the above calculated back up time to be considerably less due to many inherent inefficiencies associated with the system or the circuit.
