Explanation:Let the resistance of each resistor be R. Series connection : Equivalent resistance (maximum) R  s ​   =R+R+....+N terms ⟹ R  s ​   =nR PARALLEL connection : Equivalent resistance (minimum)   R  P ​    1 ​   =  R 1 ​   +   R 1 ​   +...+n terms We get   R  p ​    1 ​   =  R n ​    ⟹ R  p ​   =  n R ​    Thus RATION of maximum to minimum resistance   R  p ​    R  s ​    ​   =  R/n nR ​    ⟹   R  p ​    R  s ​    ​   =n  2

:The lamp consumes power of 30 watt, when connected with 12V supply. (1)Power, P = V^2/R, where R is the Resistance of the Bulb filament. R= V^2/P = 12×12/36 =4 Ohms.(2) Current DRAWN by the bulb when connected to 12 V supply is V/R = 12/4 = 3 AMPERE.

hat, three resistors of resistance 3ohm, 2ohm and 1 ohm are connected in series across a 6V battery.We have to find the current FLOWING through 1ohm resistor.Let's denote the FIRST resistor i.e. 3ohm by R1, 2ohm by R2 and 1ohm by R3.R1, R2 and R3 are connected in series and the potential difference is 6V as shown below:-------| R1 |------| R2 |-------| R3 |-----------------------------| V |-----------------------For series combination:Rs = R1 + R2 + R3For parallel combination:1/Rp = 1/R1 + 1/R2 + 1/R3Given in QUESTION that, all the resistors are connected in series. So,Rs = R1 + R2 + R3Substitute value of R1 = 3ohm, R2 = 2ohm and R3 = 1ohmRs = 3 + 2 + 1Rs = 3 + 3Rs = 6Therefore, the equivalent resistance of all the three resistors in series is 6ohm.From ohm's law we can say that,V = IRFrom above calculations we have R = 6ohm and V = 6V (given in question)Substitute the value of R and V to find the value of I (current).6 = I × 66/6 = I1 = I(All the resistors are connected in series and in series current is same.)Therefore, the current flowing through 1ohm resistor is 1A.

In the absence of external FORCE, the rate of CHANGE of momentum must be zero i.e., d/dt (pB+pA) must be zero. This is nothing but Newton's third law of motion. HENCE, third law of motion is CONTAINED in the second law.

The two MAIN systems of wiring are: (i) the TREE system, and (ii) the ring system. Out of these systems, the ring system is better. The reason is that this system of wiring is cheaper because a LOW rating wire can be USED for CONNECTION of appliances.

Clouds move because the wind is carrying the parcel of cloudy air ALONG. Wind occurs at all levels of the atmosphere from the ground up to HIGHER than a jumbo jet can fly. SOMETIMES there can be no wind on the ground, but cirrus clouds very high up can be seen MOVING because of the wind where they are.Explanation:PLS mark as brainliest answer plzzzzzzzzzzzzzzzzz✌✌and hope it help u

According to distance - TIME graph,Distance-time graph means that Distance is the y axis, and Time is the x axis.If we draw a line that is parallel to the x axis, then it's slope is null .USING the first derivative of motion, change in distance is VELOCITY.∆x=vSince the change in distance is zero, because the slope is zero, we can DEDUCE that the velocity is also zero.Hence, Option B is correct.

Translational motion is the motion by which a BODY shifts from one point in space to another. One EXAMPLE of translational motion is the the motion of a bullet fired from a gun. An object has a RECTILINEAR motion when it MOVES along a straight line.

Intermolecular Forces. Two factors determine whether a substance is a solid, a liquid, or a gas: The kinetic ENERGIES of the particles (atoms, molecules, or ions) that make up a substance. ... The attractive intermolecular forces between particles that tend to draw the particles together.A few typical solids undergo sublimation at low PRESSURES (under vacuum). At standard, atmospheric pressure, a few solids which will sublime are iodine (at slightly higher than room temperature), carbon dioxide (dry ice) at -78.5 degrees Celsius, as well as naphthalene (used in mothballs) and arsenic. Then it's CALLED sublimation. ... Sublimation is the transition of a substance directly from the solid to the gas PHASE without passing through the intermediate liquid phase.Sublimation is an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram. Those substances that dont have liquid phase due to sublimation. This happens because the vapour pressure of some substances is higher when in the solid form than the liquid form. ... Sublimation is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase.Explanation:MARK ME AS BRAINLIEST ANSWER PLZZ

At resonance condition we OBSERVE maximum current flowing in a LCR circuit.Thus, from graph both circuits have resonance frequency omega as 1we have at resonanceω2=1LCfor ω=1we have,L=1C ( ans i)(ii) POWER Factor=RZAs resistance of circuit 2 is greater than that of 1 ( can be observed from VALUE of current )Thus, power factor of 2 is greater than that of R(iii) Quality factorQ=1RLC−−√ ( for SERIES circuit )since L and C is same for both case.we see circuit (ii) has lesser value of max current correspondingly its resistancemust be greater.Thus Q∝1R we have Q factor of 1 greater than 2.

Polygon LAW of VECTOR addition states that if a number of vectors can be REPRESENTED in magnitude and DIRECTION by the sides of a polygon taken in the same order, then their resultant is represented in magnitude and direction by the closing side of the polygon taken in the opposite order.

Since all temperature VALUES are positive in the Kelvin scale, the temperature affects the magnitude of the entropy term. ...

ies of bar magnet are : Attractive Property – Magnet attracts FERROMAGNETIC MATERIALS like iron, cobalt, and nickel.Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.Directive Property – A freely SUSPENDED magnet always points in a NORTH-south direction._____________________________________________Applications of Magnets : A magnet is used to separate the useful magnetic substance like steel and iron from waste by the method of magnetic separation. This is done as follows. An electromagnet is fitted to the long arm of the CRANE. This is lowered over the heap of waste material and electromagnet is switched on._____________________________________________Question and Answer:Q1. Poles are not marked in a bar magnet. How will you find out its poles?Ans: To find out the poles, we will take another bar magnet with known poles. We will bring one of the poles of the given magnet close to the north pole of the magnet. If it attracts the pole is the south pole. If it repels it is North pole.Q2. You are provided with two identical metal bars. One out of the two is a magnet. Suggest two ways to identify the magnet.Ans: Both are freely suspended. One who will align in the north-south direction is a magnet, Bring a magnet close to both the metal bars and test with both the poles. One who shows repulsion is a magnet._____________________________________________Mark me as brainliest

In this CASE the NET force is zero.According to NEWTON's third law of motion: For every ACTION, there is an equal and opposite reaction. In this case the net force is zerohope this ANSWER will help you ✌️♥️

Distance travelled by object = half the circumference→ 1/2 × 2πr→ πrTaking π as 22/7,22/7 × 70→ 220 metres.Hence, distance travelled = 220 metres.After COMPLETING half a circle, the object will be diametrically opposite to it's inital POSITION. Now we know that displacement is the shortest distance between INITIAL and final position. Hence, it's displacement will equal the value of diameter of the circle.Diameter of circle = 2 × R = 2 × 70 m = 140 mHence, MAGNITUDE of displacement = 140 m

Unlike the dot PRODUCT, the vector product is a vector. The DIRECTION of the vector (A crossB) is defined by the so-called RIGHT-hand rule. Using the fingers of the right hand pointed in the direction of A, the fingers are rotated into the vector B(remember - the smaller of the two possible angles).

e have been provided with velocity - time graph of an object.To Discuss :Type of motion of the particle in various phases of journey using slope method Concept:We should remember that the slope of Velocity vs Time graph gives us the ACCELERATION of the particleCalculation:1. In the part O - A :So particle is following Accelerated Motion (constant Acceleration)2. In the part A - B :So particle is Following uniform motion with constant velocity3. In the part B - C :So the particle is again following Negatively Accelerated motion such that it's velocity is REDUCING .4. In the part C - D :It is still Following retarded motion with same MAGNITUDE of acceleration such that the velocity of the particle has changed its direction.The particle is MOVING in opposite direction now.5. In the part D - E :So the particle is experiencing accelerated Motion in a direction opposite to the previous part .Finally the velocity became zero .
