First let's calculate the vertical and horizontal components of the distance:

\begin{gathered} dh=19500\cdot\cos (32\degree) \\ dh=16536.94 \\  \\ dy=19500\cdot\sin (32\degree) \\ dy=10333.43 \end{gathered}

Then, since we have the time required, let's find the speed in each direction:

\begin{gathered} vh=\frac{dh}{t} \\ vh=\frac{16536.94}{9.2} \\ vh=1797.49 \\  \\ vy=\frac{dy}{t} \\ vy=\frac{10333.43}{9.2} \\ vy=1123.2 \end{gathered}

Now, let's decompose the given speed in its components:

\begin{gathered} Vh=1810\cdot\cos (20\degree) \\ Vh=1700.84 \\  \\ Vy=1810\cdot\sin (20\degree) \\ Vy=619.06 \end{gathered}

in a circuit, where do electric charges go once they have left the voltage source and traveled along the wires?
S_A_V [24]
In an electric circuit, the free electrons are moving around. Since equal charges repel and opposite charges attract, the electrons move from the negatively charged to the positively charged pole of the voltage source.

What constant acceleration is required to increase the speed of a car from 27 mi/h to 53 mi/h in 3s?
mario62 [17]

Answer:

8.87 m/s^2  

Explanation:

Acceleration is change in velocity over a change in time

27 to 53 = 26 m/s   change in velocity

26 m/s / 3 s = 8.87 m /s^2
