Atest of the prototype of a new automobile shows that the minimum distance for a controlled stop from 95 km/h to zero is 55 m. find the acceleration, assuming it to be constant as a fraction of the free-fall acceleration. the acceleration due to gravity is 9.81 m/s 2 . answer in units of g

State the right hand rule of the direction of magnetic field in a conductor carrying current

It is really hard for me right know

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?
