Please help in finding the x ohm resistor

Answer»

The equivalent resistance b/w A and B is 4 ohmClearly , 4 Ω and 8 Ω resistance are connected in series combination Thus ,R' = 4 + 8 R' = 12 ohmAlso , x Ω and 5 Ω resistance are connected in series combination Thus ,R" = (x + 5) ΩNow , The resistance R' form a parrallel combination with R" Thus , the equivalent resistance b/w A and B is ➡1/R = 1/12 + 1/(x + 5)➡1/R = (x + 17)/(12x + 60)➡R = (12x + 60)/(x + 17)SINCE , the equivalent resistance b/w A and B is 4 ΩThus ,Hence , the value of x is 1 ohm

Derive magnetic force acts on a charged particle

Answer»

For a particle moving in a plane perpendicular to external magnetic field we know that:F = qvBsinθ = mv^2/rorF = mv^2r^-1thus,r^n = r^-1orn = -1-------OR-------When a charge particle is projected with VELOCITY V perpendicular to the magnetic field,B, the force due to field isF = q(vXB), where q is charge of particle. This force is perpendicular to B and v. This fact SHOWS that the particle is moving on circular path in the field. In this situation the magnetic force PROVIDES the centripetal force necessary for circular motion. Therefore ,mv^2/r=qvB.If we stop here, then n=-1. But, if we write mv^2/r=mrw^2, then n =1.Read more on Brainly.in - brainly.in/question/5295433#readmoreExplanation:

Answer»

A concrete dam with 1.5M wide at the top, 5m wide at BOTTOM and 10M in high, with UPSTREAM face verticalTo find:  A) height of the water to be stored in the dam               B) Base WIDTH of the dam for no tension at the base of the dam when water is stored up to the top of the dam .Solution:Now we have given the dimension of dam, that is 1.5m wide at the top, 5m wide at bottom and 10m in high.So the height of the water to be stored in the dam  will be 10 m.Now we know the formula for pressure:                P = ρ1g1h1 + ρ2g2h2 So, the pressure at the bottom of the dam when it is full will be:                P = ( 2500 × 10 × 10 ) + ( 1000 × 10 × 10)                    = 350000 Pa Now the force at bottom of the dam :is:                 F = ρgAh                    = 3500 × 10 × 32.5                   = 1137500 NAnswer:               So the height of the water to be stored in the dam  will be 10 m, pressure at the bottom of the dam when it is full will be 350000 Pa  and the force at bottom of the dam is  1137500 N.
