Explanation:
Answer:
The amplitude of the wing tip's motion is 1.6 mm.
Explanation:
Given that,
Beat = 250 /s
Speed = 2.5 m/s
We need to calculate the amplitude of the wing tip's motion
Using the equation for the maximum velocity


Where,
v = speed
f = frequency
A = amplitude
Put the value into the formula



Hence, The amplitude of the wing tip's motion is 1.6 mm.
Answer:

Explanation:
Given that
B(y, t) = k y ³t²
To find the total flux over the loop we have to integrate over the loop

Given that loop is square,so

B(y, t) = k y ³t²


We know that emf given as


So

Alkali metals
Nonmetals
