The ring usually FORMS nearer to the hydrochloric acid end of the TUBE because HYDROGEN chloride diffuses more slowly than AMMONIA. This is because hydrogen chloride has ALMOST twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas.

noExplanation:the TRUCK of mass 1500 kg moves in its DIRECTION and the truck of mass 500kg MOVE along the truck which had HIGHER mass

the mass of SMALL ANIMAL is negligible as COMPARED to the mass of the earth.HOPE THE ANSWER IS HELPFUL TO YOU.

We use PARALLEL arrangement so that equal voltage is supplied to both. I would use a parallel arrangement as in SERIES if one BULB DEFECTS then the other cannot get the required CURRENT.also i would save the current. Also series circuit will have high resistance......

(B)parallel circuit Explanation:(b) parallel circuit as the VOLTAGE remains the same while in series voltage splits(c) parallel as it has the most voltage. it is also due to its high power dissipation.(d) series circuit as the circuit is broken(e)parallel as the CURRENT is SPLIT while the current STAYS the same in series circuit

Explanation: better WAY to connect lights and other electrical appliances in domestic wiring  is Parallel CircuitBecause parallel circuit will allow independent USE of light & appliances. Christmas tree lamps are usually wired in series.  if ONE lamp breaks then Whole Christmas tree stop workingAn electrician has wired a house in such a way that if a lamp gets fused in one room of the house, all the lamps in other rooms of the house stop working=> Electrician has USED series wiring instead of Parallel Wiring

(a) the law of conservation of momentum states that in the ABSENCE of net external force on the SYSTEM, the momentum of the system REMAINS unchanged m1u1+m2u2=m1v1 +m2v2(B)

cricketer does this to lower the force. When the PLAYER brings his hands backwards, it helps is increasing time of the force action. So as the time increases, the force also gets reduced and the player does not get injured in his hands.b) Given,Mass = 150 gNow, we SHALL convert it into kg.m = 0.15 kgThe starting velocity is 30 m/sSo,Starting momentum = 0.15 x 30 = 4.5 kgm/sFinal value of momentum = 0Change OCCURED for momentum = 0 - 4.5Change occured for momentum = 0 - 4.5 = -4.5kgm/sMomentum's rate of change will be =-4.5/0.05-90 NTHE value of the force exerted is 90 N

a) for every ACTION, there is an equal and opposite reaction if F1 is ACTING and F2 is REACTING then by definition F1 = -F2here (-)sign is used to SHOW opposite direction

circuit (ii), the lamps are dimmest. (b) In circuit (III) the lamps are equal brightness in circuit (i) as both are connected in parallel.(C) in circuit, (ii), gives out the maximum light.explanation : generally, brightness or dimness depends on power SUPPLIED to appliances (i.e., lamp or bulb), lamp will be more brighter when it gets more power. in case of series combination, power supplied DECREASES due to increase equivalent resistance. hence, lamp will be dimmer when resistors are joined in series combination.but in case of parallel combination, power increase due to decrease equivalent resistance. hence, lamp will be brighter when resistors are joined in parallel combination.

of unloaded truck=2000kg acceleration=0.5m/s2 FORCE= mass × acceleration F=2000kg×0.5m/s2 F= 1000N mass of LOADED truck =2000kg TOTAL mass=(2000+2000)KG =4000kg acceleration=? Force=m×a a=f/m =1000/4000 =0.25m/s2

d. YES MOVING BICYCLE is ALWAYS moving

-if one appliance does not WORK the others still work while in SERIES it does not-the voltage is the same through out the circuit-current SPLITS

udent,◆ Answers -(a) For decorating a hotel building from outside -Series connection should be preferred to decorate hotel building from outside because large no of low-power LEDs will WORK effectively in this manner.(B) For lighting inside the rooms of the hotel -Parallel connection should be used to light rooms of hotel because we need use high power BULBS to enlighten room. Also defect in individual bulb will not affect working of other bulbs.Thanks dear...

the SOLUTION. I HOPED that this solution will HELP you.

n:Solution:SONAR is an ACRONYM for SOUND Navigation And Ranging. It is an acoustic device used to measure the depth, direction, and speed of under-water OBJECTS such as SUBMARINES and ship wrecks with the help of ultrasounds. It is also used to measure the depth of seas and oceans.

Centripetal force is the NAME given to any force which causes a change in DIRECTION of velocity toward the center of the CIRCULAR motion. Explanation:The COMPONENT of the force which is PERPENDICULAR to the velocity is the part resulting in the centripetal force.

t=u/gExplanation:APPLY EQUATION of MOTIONS.

he force ACTING on an OBJECT perpendicular to the SURFACE is called thrust.PressureThe force acting per UNIT area of a surface is called pressure.♣ The thrust on unit area is called pressure.

ergy of ELECTRON in the ground state of hydrogen atom = -13.6eV when beam of electrons of energy 12.9 electron volt Banbard hydrogen atom the energy of electron in the hydrogen atom, = EN = -13.6 + 12.9 = -0. 85eV now using, En = -13. 6/N^2 we get n^2 = -13. 6/En = -13. 6/0.85= 16 n =4

The ANSWER is 2..I HOPE it's HELP you

Galileo's laws of MotionAccording to this law all bodies accelerate at the same RATE regardless of their SIZE or mass. He developed the concept of motion in terms of velocity ( speed and direction ) through the use of inclined PLANES. He is the one who developed the idea of force, as a CAUSE for motion.Through his EXPERIMENTS, he also countered the pervasive Aristotelian view, which held that heavier objects fall faster than lighter objects.

a) 5ohmb) 2ampc) 4Vd) 6VExplanation:Although the above given question has not given the circuit, but from the question we can conclude that the voltage is 10V and two resistances are 2 ohm and 3 ohm respectively.a) When two resistors are CONNECTED in series combination, the combined resistance given by them would be (2+3)ohm = 5ohm.b) We know that the amount of voltage = Amount of current passed × Resistance given.So , I = V/ R I = 10/5 [ combining resistance of two resistors in series combination, 2+3 =5] Therefore I = 2 amp.c) At 2 ohm resistor, the potential DIFFERENCE is :V= I×R So, 2×2= 4V.d) At 3 ohm resistor, the potential difference is:V= 2×3 =6V

R1 and R2 are in SERIES and RS and R3 are in parallel

action forces and reaction forces act on different objects. They are equal in magnitude and opposite in direction. they are simultaneous.Explanation:1. Action and Reaction are TERMS that express force.2. These forces act in PAIRS. One force cannot exist by itself.3. Action and Reaction forces Act simultaneously.4. Action and reaction forces act on different objects. They do not act on the same objects and HENCE CANCEL each other's effect. 5. Eg. When hitting a ball with a bat, the SPEED of the ball decreases.

a) 9.16ampb) 4.58 ampc) 18.33 ampExplanation:An electric heater is connected to a supply LINE that has a voltage of 220V.This supply line has TWO resistance coils A and B.Resistance of A is 24ohm and B is also 24ohm.So, we can conclude that resistance of A and B are equal.Now, we know that the amount of voltage PASSED = amount of current drawn × Resistance. V=IRa) So, the amount of current drawn when A coil is used is : I= V/R I= 220/24 I= 9.16 ampb) When coil A and B are being used in series the amount of current drawn is : 220/48[ Since A+B = 24+24=48] Therefore I = 4.58 ampc) When coil A and B are in parallel series, TOTAL resistance would be 1/24 + 1/24 = 2/24 = 1/12Therefore amount of current drawn is : 220/12 = 18.33ampTherefore I = 18.33 amp

iven that, CURRENT through 5Ω resistor is 1amp.all the given resistors are joined in PARALLEL combination.and we know, POTENTIAL difference across all resistors will be same if these are joined in parallel combination.so, potential difference across 5Ω resistor , V= 5Ω × 1ohm = 5volts now current through 10Ω resistor = V/R = 5volts/10Ω = 0.5Ampcurrent through 4Ω resistor = V/R' = 5volts/4Ω = 1.25 amp

a To obtain max current we will connect it in SERIES CONNECTION whereas to obtain min.current we will connect it in PARALLEL connection.b the current FLOWING in series connection is 0.4A whereas in parallel connection is 1.8A

The answer is 3 METER (in case the DISTANCE covered before applying BRAKES)While in case the distance covered after applying brakes = 18.75And hence the total distance he would cover after he sees the need to STOP = 18.75 + 3 = 21.75 meters.Explanation:Refer to the PIC.
