Answer:
5.9 km/hour
Explanation:
divide 12.5 by 2.1 and the answer is 5.9
In transversal wave particles do not oscillate along the line of the wave propagation but oscillate up and down about their mean position as the wave travels.thus transverse wave is the one in which individual particles of the medium move about their mean position in a direction perpendicular to the direction of wave propprgation.
In longitutional waves the individual particles of the medium move in the direction parallel to the direction of the propprgation of the disturbance. The particles do not move from one place to another but the simply oscillate back and forth about their position of the rest.

Answer:
Hydrogen gas/bubbles
Explanation:
Photosynthesis is defined as the process by which green plants and other organisms like blue-green algae etc. synthesize organic matter. In the presence of light energy, they convert CO2 and H2O into organic sugar with the release of O2 gas.
The plant was performing photosynthesis since there is the presence of CO2 (baking soda) and water and therefore the bubbles seen is hydrogen gas guven off from photosynthesis .
6CO2(g) + 6H2O(l) --> C6H12O6(s) + 6O2(g)
Answer:
Average acceleration = 6m/s²
Explanation:
Given the following data;
Initial velocity, u = 4m/s
Final velocity, v = 22m/s
Time, t = 3 seconds
To find the average acceleration;
Acceleration = (v - u)/t
Substituting into the equation, we have;
Acceleration = (22 - 4)/3
Acceleration = 18/3
Acceleration = 6m/s²
Answer:
kinetic energy
Explanation:
Kinetic energy is energy in motion
