Answer:
F = M a = M v^2 / R
If v is increased by three the force will be increased by nine,
C) is correct
Answer; transverse wave
Explanation;
In transverse waves the particles vibrate perpendicular to the wave's motion.
Answer:
0.63 s
Explanation:
We have,
- Height, h = 2.0 m
- Initial velocity, u = 0 m/s
- Acceleration due to gravity, g = 10 m/s²
We have to find the time taken.
⠀⠀⠀⠀⇒ h = ut + ½gt²
⠀⠀⠀⠀⇒ h = ½gt²
⠀⠀⠀⠀⇒ 2 = ½ × 10 × t²
⠀⠀⠀⠀⇒ 2 = 5 × t²
⠀⠀⠀⠀⇒ 2/5 = t²
⠀⠀⠀⠀⇒ √(2/5) = t
⠀⠀⠀⠀⇒ <u>0.63 s = t</u>
Therefore, time taken is 0.63 seconds.
Answer:
= 1227.9K
Explanation:
Given that,
D₀ = 4.0 x 10⁻⁵ m²/s,
Qd = 230,000 J/mol,
D = 6.48 x 10⁻¹⁵ m²/s
Gas constant R = 8.31 J/mol-K
T = 
= 
= 
= 1227.93K
≅1227.9K
