The natural frequency is determined by the largest half wavelength that will fit in the body. Since frequency is inversely proportional to the wavelength, larger bodies have lower frequencies. This is why larger musical instruments are typically used for bass and smaller ones (like piccolos) are used for high frequencies
Answer:
The North Atlantic Treaty or Washington Treaty
Explanation:
The North Atlantic Treaty or Washington Treaty is the treaty that constituted the North Atlantic Treaty Organization (NATO). It was signed in Washington on April 4, 1949.
There it is established that the purpose of NATO is to guarantee the freedom and security of its member countries through political and military means.
Answer: The reason weight for average adult is 530N
Explanation: The clearly see this answer, let's convert this weight to kg using F=mg
530=m×9.8
g is a constant of 9.8m/s2
We divide both sides by 9.8 to get
54kg then this weight is reasonable for an average adult.
Answer:
solved
Explanation:
a) F_net = (F2 - F3)i - F1 j
b) |Fnet| = sqrt( (F2 - F3)^2 + F1^2)
= sqrt( (9- 5)^2 + 1^2)
= 4.123 N
c) θ = tan^-1( (Fnet_y/Fnet_x)
= tan^-1( -1/(9-5) )
= -14.036°
Answer:
The angle of the launch is 17.09 degrees.
Explanation:
Given that,
The initial speed of a cannon is 100 m/s
It is launched at some angle and it lands after being in the air for 6 s.
We need to find the angle of the launch.
The time taken by the projectile to reach the ground is called the time of flight. It is given by the formula as follows :
Here, = launch angle
Hence, the angle of the launch is 17.09 degrees.
