An outlet of diameter 1 m is made 20 cm below the surface of water in a dam what would be the force with which the water spews out when it is fully opened (taking g as 10 Nkg -1and density of water 1gcm-3 )​

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?
