Answer:
1.0 m/s
Explanation:
First, convert to SI units.
0.30 km × (1000 m / km) = 300 m
5.0 min × (60 s / min) = 300 s
Speed is distance divided by time:
300 m / 300 s = 1.0 m/s
When an object in simple harmonic motion is at its maximum displacement, its <u>acceleration</u> is also at a maximum.
<u><em>Reason</em></u><em>: The speed is zero when the simple harmonic motion is at its maximum displacement, however, the acceleration is the rate of change of velocity. The velocity reverses the direction at that point therefore its rate of change is maximum at that moment. thus the acceleration is at its maximum at this point</em>

Answer:

Explanation:
We have given mass m=0.155 kg
Force constant K = 305 N/m
Distance 
Velocity 
The total energy at any position of the motion is give by
here
is energy due to motion and
is energy due to spring elongation
So total energy 
Answer: ionic bond
Explanation: This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge.
Answer:
Explanation:
The velocity is 340, but the distance is not. Here's how you do this:
You need to find out the velocity of the that sound in that temp which has a formula of
v = 331.5 + .606T where T is the temp in Celcius. Filling in and using the correct number of sig dig:
v = 331.5 + .606(20) and
v = 331.5 + 10 and
v = 340 m/s. Now we need to use that in d = vt:
d = 340(2.00) so
d = 680 m
