Answer:
i believe there is something wrong in your question
Explanation:
B. Reversing the current direction will cause the force deflecting the
wire to be perpendicular to the magnetic field but in the opposite
direction.
Answer:
the index of refraction of the other material = 1.31
Explanation:
Critical angle is given by the formula;
sin(θ_crit) = n_r/n_i
Where;
θ_crit is critical angle
n_r is index of refraction of the Refractive medium
n_i is index of refraction of incidence medium
We are given that θ_crit = 81° and n_i = 1.33
Thus;
sin 81 = n_r/1.33
n_r = 1.33 × sin 81
n_r = 1.33 × 0.9877
n_r ≈ 1.31
Answer:
Each jump covers one center of the square to the other. If you can imagine the scenario, a single jump would cover a length of the side of one whole square. So, if it took three jumps, the total distance would be
d = 3 * 5 cm
d = 15 cm
Therefore, the magnitude or distance is 15 cm. The displacement depends on the direction of motion.
