Velocity = Frequency x Wavelength
= 18 x 13 = 234 mm/s
The magnitude of the action–reaction pair between the two boxes (A and B) will be "18.2 N".
According to the question,
Mass of box A,
Mass of box B,
Horizontal force,
From the Newton's law,
→ 
or,
→ 
Bu substituting the values, we get
→ 
→ 
→ 
We can see that between the two boxes, the action-reaction pair exist.
then,
→ 
→ 
→ 
(magnitude)
Thus the above solution is appropriate.

Answer:
Width = 680 [m]
Explanation:
To solve this problem we must know the speed of sound in the air, conducting an internet search, we find that this speed has a value of v = 340 [m/s].
We apply the following kinematic equation, which relates space to time, to define speed.
v = x /t
where:
x = distance [m]
t = time [s]
v = velocity [m/s]
Now replacing:
x = 340 * 4
x = 1360 [m]
But the width of the cannon is calculated when the sound wave hits the wall of the canyon, so this width is half the distance.
Width = 1360 / 2 = 680 [m]
Answer:
4.78 × 10⁻³ T.m²
Explanation:
The expression for the magnetic flux is given by
∅ = BAcosФ
where B = magnetic field strength
A = Area of circular loop = πr²
r = radius of the wire loop
substitute πr² for A in the first equation
∅ = Bπr²cosФ
∅ = 2.55 × 3.14 × 0.025² × cos 17.3°
∅ = 4.78 × 10⁻³ T.m²
OR
0.00478 T.m²
