A body moves in a straight line with a uniform acceleration of 2 m / s. If the initial velocity of the body is 10 m / s, find the velocity of the body after covering 75 m and the time taken by the body to attain this velocity.

I'm thinking it's 2 you are asked to explain the earth's magnetic field. which is the best reply? 1. the earth's magnetic south is similar to the north pole of a magnet. 2. the earth's core has a strong magnetic charge similar to the south pole of a magnet. 3. the earth's geomagnetic south is similar to the south pole of a magnet. 4. the earth's magnetic charge is not centered at either pole; it varies based on location.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
