A car moves with a velocity of 12 rad/s in a curved road. If the driver used the break system to stop the car within 120m, Calculate the
angular acceleration was the driver moving the car with it. (r = 60 ml

The force will determine the acceleration.

There are weak or strong attractive forces between atoms of liquids with a high viscosity

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
