he circuit on the LEFT side,Potential difference = 10 VResistance = 5 ΩWe KNOW,V = IR⇒10 = I × 5⇒I = 10/5⇒I = 2 A◙ For the circuit on the right side,Potential difference = 20 VResistance = 10 ΩWe know,V = IR⇒20 = I × 10⇒I = 20/10⇒I = 2 AAs the 2 Ω resistor is connected with both the circuits in series, so the current flowing through the 2 Ω resistor is 2 - 2 = 0 A. (As the current of 2 A is reserved for the RESPECTIVE circuits, and don't flow beyond that.)

hat, an object of mass 10kg placed on the smooth horizontal table initially at rest. ALSO, a force of 10N acts on object.W have to find the displacement of the object after 5sec.From above data we have, mass (m) = 10 kg, force (F) = 10N and time (t) = 5 secForce is defined as the product of mass and acceleration. i.e.F = maSubstitute the known values in the above formula,10 = 10aDivide by 10 on both sides,10/10 = 10a/101 = aTherefore, the acceleration is 1 m/s². But we have to find the displacement (s) of the object.Using the Third Equation Of MOTION,s = UT + 1/2 at²Initial velocity of the object is 0 m/s because initially object is at rest.s = 0(5) + 1/2 × 1 × (5)²s = 0 + 1/2 × 25s = 25/2s = 12.5Therefore, the displacement of the object is 12.5 m.

Explanation:A body of mass m hung at one end of the spring executes simple harmonic motion . The force constant of a spring is k while its period of vibration is T. Prove by dimensional method that the equation T=2πm/k is correct. ... As the DIMENSIONS of two sides are not equal , hence the equation is incorrectCmk−−−√  Solution : The GIVEN equation is T=2πmk Taking the dimensions of both sides, we have [T]=[M][ML0T−2]=T2 As the dimensions of two sides are not equal , hence the equation is incorrect. Let the correct relation be T=Cmakb,whereC is constant. Equating the dimensions of both sides , we get [T]=[M]a[MT−2]b or [M0L0T]=[Ma+bL0T−2b] COMPARING the POWERS of M,L, and T on both sides , we get a+b=0and−2b=1. Therefore , b=−12anda=12 :. T=Cm−1/2k−1/2=Cmk−−−√ This is the correct equation

the capacitor was connected to 10 V for charging to 30mC.After disconnected let's say ‘Q’ total charge 30mC in capacitor (C1) is stored. After we connected it to ANOTHER uncharged capacitor let's say (C2) the charge in C1 start decreased and it will DECREASE till equilibrium is reached.So total charge will be then GIVEN byQ=Q1+Q2 where Q1 is charge at C1 and Q2 for C2 ,as C1 is double of C2 the charge will also be double at C1 Q=2Q2+Q2So after solving this we find charge at C1 will be 20mC and C2 will be 10mc

d for the preparation of solidified colloidal SULPHUR media. Tuovinen OH. The chemical reaction between TETRATHIONATE and sulphide produces colloidal sulphur and thiosulphate. This reaction can be employed to prepare agar media containing thiosulphate and finely divided colloidal sulphur particles.Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher INDOORS (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands.Organic chemicals are widely USED as ingredients in household products. Paints, varnishes and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.

magnetic Force : It includes electric and magnetic forces. If two particles having charges q, and qare at rest and at distance r, the force between them is given as :F = 1/(4πєo) × (Q1Q2)/r².This is KNOWN as Coulomb force. This force is attractive if charges are of opposite nature (one positive and the other negative). Otherwise, it isrepulsive. Charges in MOTION produce magnetic effects and a magnetic field gives rise to a force on a moving charge. Electric and magnetic effects are inseparable, hence the name electromagnetic force. Electrical repulsion between two protons at a given distance is 1036 times stronger than their GRAVITATIONAL attractive force.
