Calculate Effective resistance and total current 5 diagram

Answer»

Explanation:formula resistances to connect parallel = 1/r+ 1/r+2/r resistance to connect series = r+r+r However, if you had a huge and complicated circuit with MANY resistors, then the EFFECTIVE resistance is the total resistance of the circuit. Effective resistance is usually measured between 2 points. In the figure above, the effective resistance is generally DEFINED as the total resistance across the battery. please follow me and mark as brainliest answer

A disc without slipping rolls down a hill of height 10m .it is a disc starts from the rest at the top of the hill. what is the speed at the bottom?

Answer»

c is placed at the top of a hill of height 1000 cm = 10 m. It posses potential ENERGY which is converted to kinetic energy as it rolls down. The motion of the disc during ROLLING down is of two TYPES; linear and rotational and hence do the kinetic energy. As the P.E is converted to K.E (WITHOUT slipping means there is no friction and all the potential energy is converted to  kinetic energy), therefore,Loss in potential energy = Gain in kinetic energyGiven                        Height = 10 m               vi = 0 m/s             g = 9.8 m/s2Required                  vf =?Now P.E = mgh, therefore,PUTTING these values,Putting the values

Focal length of concave lens is 15cm.if an image is 10cm away from this lens, at what distance the object from the lens is placed?

Answer»

- 6cm or 6 cm away from the lensExplanation:we know LENS FORMULA, 1/F = 1/v - 1/U,where f is FOCAL length            v is position of image             u is position of objecthere, by putting values we get1/15 = -1/10 - 1/u1/15+ 1/10 = - 1/uby taking lcm(2+3)/30 = -1/u5/30  = -1/u1/6  = -1/uu = -6 cm
