We begin by investigating whether the lengths are the same. find the length of the vector, c, starting with the components given in equations 3 and 4.express your answer in terms of a, b, and θ.equation 3: \evec{c}_x = a + b\cos(\theta) andequation 4: \evec{c}_y = b\sin(\theta).c = somehow do not understand how to get the problem right on mastering engineering. i square each equation, add them, and use the pythagorean theorem.

When you turn on a battery-operated device, an electrical circuit is

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
