Answer:

A chemical reaction expresses a chemical change. For example, one chemical property of hydrogen is that it will react with oxygen to make water. We can write that as follows:

hydrogen reacts with oxygen to make water

We can represent this chemical change more succinctly as

hydrogen + oxygen → water

A baseball is thrown horizontally from a cliff at 30 m/s and lands 7 seconds after the baseball was thrown. Calculate the horizo

ASHA 777 [7]

Answer:

The horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively.

Explanation:

Using the equation of the displacement in the x-direction, we have:

(let's recall we have a constant velocity in this direction)

$x=v_{ix}t$

Where:

v(ix) is the initil velocity in the x direction (v(ix) = 30 m/s)
t is the time (t = 7 s)

$x=30(7)$

$x=210\: m$

Now, we need to use the equation of the displacement in the y-direction to find the vertical distance. Here we have an acceleration (g)

$y=v_{iy}t-\frac{1}{2}gt^2$

Where:

v(iy) is the initial velocity at the y-direction. In this case, it will be 0
t is the time
g is the acceleration of gravity (g=9.81 m/s²)

Then, the vertical position at 7 s is:

$y=-\frac{1}{2}(9.81)(7)^2$

$y=-240.35\: m$

Therefore, the horizontal and vertical distances are x = 210 m and y = -240.35 m, respectively. The minus sign means the <u>negative value in the y-direction.</u>

I hope it helps you!

Use the circuit diagram to determine the voltage drop across the 8 Ω resistor.

Rainbow [258]

First we need to find the current flowing in the circuit. The three resistors are in series, so the equivalent resistance of the circuit is the sum of the three resistances:
$R_{eq} = R_1 + R_2 + R_3 = 10.0 \Omega + 8.0 \Omega +6.0 \Omega = 24.0 \Omega$

Then we can apply Ohm's law to the whole circuit, to find the current flowing:
$I= \frac{V}{R_{eq}}= \frac{12 V}{24.0 \Omega}=0.5 A$

And now we can apply Ohm's law to the resistor of $8.0 \Omega$ to find the voltage drop across it:
$V_{8\Omega} =IR=(0.5 A)(8.0 \Omega)=4 V$
