• Component of B perpendicular to the plane = Bcos25° => emf induced in the coil ε = Bcos25° * 1.2 * v = => current in the bar, I = ε/R = (v/R) * 1.2 Bcos25° Force opposing the downward motion F = I * L * Bcos25° = (v/R) * (1.2 Bcos25°…

• Let t = time for the stone to reach the ground => 125 = 4.905t^2 => t = √(125/4.905) = 5.0482 seconds Time for the sound to reach the top after the stone reached the ground = 125/343 = 0.3676 sec. Time of hearing the sound after the…

• V=1/2 (w)(L)(h) This formula is for right triangular prism. If the triangular base is just any triangle, then formula is Area of triangle * length of prism Area of any triangle can be known if the lengths of three sides, a, b, and c are known…

• x^10 - 9x^8 + x^7 + 4x^6 - 9x^5 - 36x^4 + 4x^3 - 36x = (x^10 + x^7 + 4x^6 + 4x^3) - (9x^8 + 9x^5 + 36x^4 + 36x) = x^3 (x^7 + x^4 + 4x^3 + 4) - 9x (x^7 + x^4 + 4x^3 + 4) = x(x^2 - 9) [x^7 + x^4 + 4(x^3 + 1)] = x(x - 3)(x + 3)[ x^4(x^3 + 1) + 4(x^…
