A projectile is in perfect-parabola motion. It has an initial velocity of Vi at an angle of θ, above the horizontal. It reaches the highest point of the arc, h max at time 't'. It has gone a horizontal distance 'd' at the maximum height. all of the following are true except:

Who was the first scientist to measure speed as distance over time?

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.
