Answer:

45.6 m at 80.5^{\circ} south of west

Explanation:

Let's take the north-south direction as y-direction (with south being positive) and east-west direction as x-direction (with west being positive). Therefore, the two components of Cody's motion are:

- d_y = 45.0 m (south)

- d_x = 7.50 m (west)

Since they are perpendicular, the magnitude of the net displacement can be calculated by using Pythagorean's theorem:

d=\sqrt{d_x^2+d_y^2}=\sqrt{7.50^2+45.0^2}=45.6 m

The direction instead can be measured as follows:

\theta = tan^{-1} (\frac{d_y}{d_x})=tan^{-1}(\frac{45.0}{7.50})=80.5^{\circ}

And given the convention we have used, this angle is measured as south of west.

A closed system’s internal energy changes by 178 J as a result of being heated with 658 J of energy. The energy used to do work
nika2105 [10]

Answer:

480J

Explanation:

Using the formula:

Delta U = Q - W

Q:Heat (J)

Delta U: Changes in internal Energy (J)

W:Work (J)

We can plug in the give numbers, Q and W.

Delta U = 658J - 178J = 480J

Lisa [10]

Answer:

<h2>30 N</h2>

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 15 × 2

We have the final answer as

<h3>30 N</h3>
