The diver most likely refers to the ocean's surface when describing the squid's location. Option A is correct.
<h3>What is the height?</h3>
The vertical distance between the object's top and the bottom is defined as height. It is measured in centimeters, inches, meters, and other units.
The organism is shown as;
Seaweed = - 20 meters
Clownfish = - 23 meters
Squid = - 44 meters.
The given data is a reference from the surface of the ocean. The negative sign in the data shows that the given height is below the ocean surface.
The diver most likely uses the ocean surface as a reference point to describe the position of the squid.
Hence, option A is correct.

Answer:
a) T = 1,467 s
, b) A = 0.495 m
, c) v = 4.97 10⁻² m / s
Explanation:
The simple harmonic movement is described by the expression
x = A cos (wt + Ф)
Where the angular velocity is
w = √ k / m
a) Ask the period
Angular velocity, frequency and period are related
w = 2π f = 2π / T
T = 2π / w
T = 2pi √ m / k
T = 2π √ (1.2 / 22)
T = 1,467 s
f = 1 / T
f = 0.68 Hz
b) ask the amplitude
The mechanical energy of a harmonic oscillator
E = ½ k A²
A = √2 E / k
A = √ (2 2.7 / 22)
A = 0.495 m
c) the mass changes to 8.0 kg
As released from rest Ф = 0, the equation remains
x = A cos wt
w = √ (22/8)
w = 1,658
x = 3.0 cos (1,658 t)
Speed is
v = dx / dt
v = -A w sin wt
The speed is maximum when without wt = ±1
v = Aw
v = 0.03 1,658
v = 4.97 10⁻² m / s
Answer with Explanation:
We are given that
a.We have to find the torque on the particle about the origin.
We know that
Torque=
By using the formula
b.
Substitute the values then we get
Because 
Answer:
Electromagnetic wave are waves formed as a result of the oscillatory activities involving the electric and the magnetic field.
However in an Electromagnetic wave, the electric field and magnetic field carry equal amounts of energy and the magnitude of the electric field is directly proportional to the magnitude of the magnetic field. This direct proportionality gives rise to the speed of light being the constant between the two fields.
When the electric field is doubled then an equal action is to be set for the magnetic field so it doesn’t deviate from its main functions and characteristics.
