3.) Find μ so that x - 3 is a factor of μx³ - 13x² - μx - 3.

A step down transformer has 3200 windings in the primary coil and a primary voltage of 100 V. determine the number of windings in the secondary coil if the secondary voltage is 45 V.

An object (m=5kg) moves from 15 m/s to 10 m/s in 5 sec. what is its change in kinetic energy?

The coefficient of friction of the box (m = 183 183 kg) and μs = 0.15 between the car platform 0.15 . Specify the shortest time for the car to reach speed 60.0 km / h without the box sliding on the car platform?

Which mdern devices works on the principle of maxwell's equations. I need atleast 15 names.

Use the Remainder Theorem to determine the remainder when P(x) is divided by D(x). Determine if D(x) is a factor of P(x).

1. P(x) = x³ - x² + x - 1; D(x) = x - 1
2. P(x) = 20x³ - 17x² + 6x - 26; D(x) = x + 1
3. P(x) = 2x³ - 5x + x² + 2; D(x) = x + 2
4. P(x) = 12x³ - 8x² + 4x - 3; D(x) = 2x - 1

Divide P(x) by D(x) using synthetic division. Write P(x) in the form Q(x)D(x) + R(x).

1. P(x) = x⁴ + x³ - 3x² - 5x - 2; D(x) = x - 2
2. P(x) = x³ - 9x - 12; D(x) = x + 3
3. P(x) = -2x³ - 5x⁴ + 2x⁵ - 3x + 1; D(x) = 2x - 1
4. P(x) = 4x⁴ - 3x² + x - 17; D(x) = 2x + 3

A spaceship travelling between the earth and the moon.the distance between the center of the earth and the moon is 3.8x10⁸m.calculate the distance of spaceship from the earth when it experiences zero gravitational force.(mass of the earth=5.97x10²⁴kg;mass of the moon =7.35x10²²kg)

show that [x, e^iap/h]= -ae^iae/h
