Three resistors are connected in series across a battery. the value of each resistance and its maximum power rating are as follows: 6.7ω and 15.9 w, 30.4ω and 9.12 w, and 16.3ω and 12.3 w. (a) what is the greatest voltage that the battery can have without one of the resistors burning up? (b) how much power does the battery deliver to the circuit in (a)?

Describe uniform velocity and variable velocity in short

Acar starts from rest at a stop sign and reaches a velocity of 25 m/s w in 4 seconds. determine the acceleration of the car. question 3 options: a) 6,25 m/s2 b)6.25 m/s c)100 m/s2 d)100 m/s

Currents in dc transmission lines can be 100 a or higher. some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. for a line that has current 150 a and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? express your answer in teslas and as a percentage of the earth’s magnetic field, which is 0.50 g. is this value cause for worry?
