The height of the steel beam is 30.9 m
Explanation:
The gravitational potential energy of an object is the energy possessed by an object due to its position in the gravitational field. Near the Earth's surface, the gravitational potential energy of an object is given by
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object above the ground
For the steel beam in this problem, we have:
U = 100,000 J is the potential energy
m = 330 kg is the mass
Solving for h, we find the height of the steel beam:

The dog whistle is manipulating frequency. This is further explained below. Option B is correct.
The sound of a high-pitched sound is harsh and has a high pitch. Examples are:
In conclusion, for a high pitch, we alter the frequency.

Answer:
Frequency
Explanation:
(I believe don't count me on this) Amplitude is the wave height otherwise known as how loud it is or the maximum displacement of vibrating particles
