Answer:
Matter is anything that has mass and occupies space. The flame itself is a mixture of gases (vaporized fuel, oxygen, carbon dioxide, carbon monoxide, water vapor, and many other things) and so is matter. <em><u>The light produced by the flame is energy, not matter.</u></em>
<em><u></u></em>
Answer:
1:knowledge of the structure of DNA
2:an understanding of hemoglobin
4:ground fault circuit interrupters
7:aerogel
Explanation:
Explanation:
Work Done = Force * Displacement
= (4N)(10m) = 40J.
Power = Work Done / Time
= (40J)/(20s) = 2J/s = 2 Nm/sec.
Centripetal Force, F = mv²/r
Where m = mass in kg, v = velocity in m/s and r = radius of curvature in m.
Centripetal Force, F = 2000 * 25² / 80. Use your calculator.
F = 15 625 N.
Answer:
1.241/s
Explanation:
From this question, we have the following information:
Mass of oscillator = 310
The time Period, t = 0.180
Decrease = 20 %
Amplitude of oscillation has the formula
A = Aoe^yt
1-20% = 80%
= 0.80
Y x 0.18 = -ln(0.8)
= 0.18Y = 0.2234
Y = 0.2233/0.18
Y = 1.241/s
The damping constant y is Therefore equal to 1.241s
