Answer:
Explanation:
Stokes' theorem relates a surface integral of a the curl of the vector field to a line integral of the vector field around the boundary of the surface.
<span>So we wan't to know which harmonic is the frequency of Fn=1056 Hz if we know that the fundamental frequency F1=528 Hz. So the frequency of n-th harmonic Fn is fundamental frequency F1 multiplied by n or Fn=n*F1. In our example we know the fundamental frequency and an overtone frequency and we want to know which harmonic it is so we are looking for n. So n=Fn/F1 and after we input our numbers we get that n=1056/528=2. So the frequency of 1056 is the frequency of the second harmonic.</span>

Answer:
3.1 s
Explanation:
we can assume that this motion has a horizontal projectile motion.
projectile motion happens when an object is subjected to only gravity. Gravity acts to influence the vertical motion of the projectile, it makes a vertical acceleration.
The horizontal motion of the projectile is the result of the constant velocity of the object.We assume no acceleration in the horizontal direction.
applying motion equations
where
s - distance
u - initial velocity
a-acceleration
t - time
s = ut + (1/2)at²
→ 165 = 50t + 0 (as no acceleration is in horizontal direction)
t = 3.1 s
Rearrange the equation F = ma to solve for acceleration. You can change this formula around to solve for acceleration by dividing both sides by the mass, so: a = F/m. To find the acceleration, simply divide the force by the mass of the object being accelerated.
This equation is the sum of n forces acting on an object. The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object, as shown in this formula. or F=ma which is force =mass*accleration
