What can be said about the relative direction of the contributions due to the entire segments KL, LM, and MN to B⃗ net at point P? What can be said about the relative direction of the contributions due to the entire segments KL, LM, and MN to at point P? The magnetic fields due to KL and MN have the same direction; the magnetic field due to LM has the opposite direction. The three magnetic fields have different directions. All three magnetic fields have the same direction.

The base of a 50-meter tower is at the origin; the base of a 50-meter tree is at (0, 50, 0). the ground is flat and the z-axis points upward. the following parametric equations describe the motion of six projectiles each launched at time t = 0 in seconds. (i) r (t) = (50 + t2)k (ii) r (t) = 2t2 j + 2t2k (iii) r (t) = 50 i + 50 j + (50 − t2)k (iv) r (t) = 2t j + (50 − t2)k (v) r (t) = (50 − 2t) i + 2t j + (50 − t)k (vi) r (t) = t i + t j + tk (a) which projectile is launched from the top of the tower and goes downward? at time t = , the projectile hits the ground at point (x, y, z) = . (b) which projectile hits the top of the tree?
