<h2>Greetings!</h2>
Firstly, to find speed you need to remember the speed formula:
Speed = Distance ÷ Time
You can do it by doing 2800 ÷ 2 but that gives m/h (metres per hour)
So to convert hours into seconds, you multiply 2 by 7200 (amount of second in 2 hours:
2 * 7200 = 14400 seconds
Now we can do distance ÷ time by plugging the values in:
2800 ÷ 14400 =
≈0.194
<h3>So the average speed is 0.194m/s (metres per second) </h3><h3 /><h2>Hope this helps!</h2>
"<span>The process by which your body converts food into energy", sounds more accurate.
"</span><span>The amount of potential energy contained in food", is basically a long way of saying - Calories.
So, I would go with the one that talks about the process of converting food to energy.</span>
Answer:
Take the numbers and fill them in graph.
Plot time as X and speed as Y and afterward join then like a line graph.
Answer:
145.52137 m/s
1.4 m
0.7 m
60.6339 Hz
121.2678 Hz
Explanation:
T = Tension = 120 N
= Linear density = 
m = Mass of wire = 6.8 g
L = Length of wire = 1.2 m
n = Number of loops
Velocity is given by

The speed of waves on the wire is 145.52137 m/s
Wavelength is given by

The wavelength of the waves that produces one-loop standing waves is 1.4 m

The wavelength of the waves that produces two-loop standing waves is 0.7 m
Frequency is given by

The frequency of the waves that produces one-loop standing waves is 60.6339 Hz

The frequency of the waves that produces two-loop standing waves is 121.2678 Hz
Answer:
I think so
Explanation:
When the object is moving towards you the sound gets louder but when it's moving away it sounds farther away.
