Answer:
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
Answer: Gamma rays
Explanation: Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
Answer: 0.002 newtons
===================================================
Work Shown:
I'm assuming you meant to write "at 20 m/s^2" at the end. If so, then,
0.10 grams = 0.10/1000 = 0.0001 kg
m = 0.0001 kg = mass
a = 20 m/s^2 = acceleration
F = ma .... newton's second law
F = 0.0001*20
F = 0.002
The force required is 0.002 newtons
gaining thermal energy in form of heat
Explanation:
When the thermal energy of a matter is increasing, it will directly increase the kinetic energy of the matter.
- Temperature changes causes the average kinetic energy of molecules to increase or decrease.
- If the kinetic energies of particles are increasing, the temperature must have been on rise.
- Increase in temperature causes molecules to start vibrating and moving about.
- The gain more energy that helps them to move away from their original position

Answer:
The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 
.
Explanation:
Velocity is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. Then, the average velocity relates the change in position to the time taken to effect that change.
Velocity considers the direction in which an object moves, so it is considered a vector magnitude.
In this case, the displacement is 192 m and the time period is 8 s. Replacing:
Solving:
velocity= 24
<em><u>The average velocity of a train moving along a straight track if its displacement is 192 m was during a time period of 8.0 s is 24 </u></em><em><u>.</u></em>
