Particle initially located at the origin has an acceleration of vector a = 2.00ĵ m/s2 and an initial velocity of vector v i = 6.00î m/s. (a) find the vector position of the particle at any time t (where t is measured in seconds). ( t î + t2 ĵ) m (b) find the velocity of the particle at any time t. ( î + t ĵ) m/s (c) continued in next problem with new numbers. find the coordinates of the particle at t = 5.00 s. x = m y = m (d) find the speed of the particle at t = 5.00 s. m/s

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
