Answer:
0.256 m/s
Explanation:
Speed is distance over time.
Find the speed of each trial and then find the average.
Trial 1: v = 0.7 m / 2.5 s = 0.280 m/s
Trial 2: v = 0.7 m / 2.75 s = 0.255 m/s
Trial 3: v = 0.7 m / 2.98 s = 0.235 m/s
v_avg = (0.280 m/s + 0.255 m/s + 0.235 m/s) / 3
v_avg = 0.256 m/s
Round as needed.
If he wants to increase power, force must increase and decrease time.
Answer:
emission line or absorption line
Explanation:
A spectral line is uniform bands of bright and dark fringes. visible spectrum are just due to string spectral line which is unique for a different element.
when there is the transmission of an electron from one energy to another ( higher to lower energy level), there is the emission of photons that lead to emission-line on the spectrum while on the other side, the absorption line is formed when electron moves to the next level by absorbing electron.
Answer:
The force and texture of an object matter a lot.
Explanation:
If you were to try and run up a glass hill, could you? You maybe could, but it would be harder to than up carpet.
