Answer:
<em>500Hertz</em>
Explanation:
Given the fundamental frequency of the string given as 1.25x10²Hz
Harmonics are integral multiples of the fundamental frequency.
In strings, the third harmonic F3 is expressed in terms of the fundamental frequency expressed as;
F3 = 4F0
F0 is the fundamental frequency;
Given
F0 = 1.25x10²Hz
F3 = 4(1.25x10²)
F3 = 4(125)
F3 = 500Hz
<em>Hence the frequency of the third harmonic is 500Hertz</em>

Answer:
8.95 m/s
Explanation:
(3.5-1.0) x 2 = gt²
t = √5/9.8 = 0.714 sec
= X/t = 4/ 0.714 = 5.602 m/s
vertical velocity means it has to rise 1.0 m against gravity in 0.714s
= gt = 9.8 x 0.714 = 6.99 m/s
V = √²+ ² = √6.99²+5.602² = 8.95 m/s
Answer: D
X and Y
Explanation:
X The least amount of magnesium Took in magnesium
Y Slightly less magnesium than the cell Took in magnesium
Because active transport occurs when ions or molecules move from less concentration region to high concentration region through semi membrane with the help of some energy.
