Answer:
Mass = 2154 grams
Explanation:
Given the following data;
Acceleration = 520m/s²
Force = 11.2N
To find the mass;
Force = mass * acceleration
Mass = force/acceleration
Substituting into the equation, we have;
Mass = 11.2/520
Mass = 2.154 kg
Therefore, the value of mass in grams;
1000 grams = 1 kilograms
x grams = 2.154 kilograms
Cross-multiplying, we have;
2.154 * 1000 = 2154 grams.
Mass = 2154 grams.
Therefore, the mass of the model rocket is equal to 2154 grams.
Answer:
1.234567 kA
Explanation:
The prefix k stands for kilo-, or 10³. The prefix m stands for milli-, or 10⁻³. The sum shown is ...
1.234 kA + 0.000567 kA = 1.234567 kA
This Question has mistakes.Correct question is
An undamped oscillator has period τo=1.000s
, but I now add a little damping so that its period changes to τ1=1.001s.
What is the damping factor β? By what factor will the amplitude of oscillation decrease after 10 cycles? Which effect of damping would be more noticeable, the change of period or the decrease of the amplitude?
Answer:
β=0.28 /sec
Amplitude=0.0606
Explanation:
When water vapor (from condensation) comes close to something cold (like the drinking glass), the molecules of both the vapor and glass slow down and will form liquid water drops on the outside of the drinking glass.
