Answer:
a = 4.59 m/s²
Explanation:
given,
initial speed of the car = 0 m/s
final speed of the car = 145 km/h
1 Km/h = 0.278 m/s
145 Km/h = 145 x 0.278 = 40.31 m/s
time, t = 8.78 m/s
Acceleration of car before collision
a = 4.59 m/s²
The magnitude of acceleration before collision is 4.59 m/s²
The answer is A, an insulator.
N2+3H2->2NH3
When 3 moles of H2 react, they produce 2 moles of NH3
3 moles of H2 have a mass of 2.02 g
2 moles of NH2 have a mass of 17.0 g
So when 2.02 g H2 react, they produce 17.0 g NH3
If 26.3g H2 react with a yield of 100%, we expect…
2.02g H2_____17.0gNH3
26.3g H2_____x=221gNH3
So now let’s calculate the percentage:
221gNH3_________100%
79.0gNH3_________x=79.0*100/221=35.7%
Answer:
These terms overlap in meaning, but: "harmonic" includes the fundamental frequency and all of the overtones above it, while "overtones" include all frequencies greater than the fundamental frequency. The harmonics are multiples of the fundamental frequency.
Explanation:
Answer:
3.78 m on the left side of the seesaw
Explanation:
The net torque in this situation is zero, so the torque from each side of the pivot point must balance each other out:
(50.0 kg x 10.0 m/s^2)(3.4m) = (450 N) r
Solve for r, and you get 3.78 on the left side.
Hope this helps!
