A 38-kg canoe breaks free from its dock and floats downriver at a speed of 2.2 m/s. What is the momentum of the canoe? 48.0 m/s
Brut [27]
Momentum of a body is calculated by multiplying the mass of a moving body with its velocity. When a body is at rest it has zero momentum since the velocity is also zero.
In this case the momentum of the canoe will be;
 38 kg × 2.2 m/s = 83.6 kgm/s
Therefore, the correct answer is 83.6 kg m/s

Justina dreamed last night that she was warding off villains in a life or death battle outside a fortified castle. In the dream,
zubka84 [21]

As a therapist who specializes in dreams, I would interpret Justina’s dream by using: 17. Freud’s wish-fulfilling theory.

<h3>Who is Sigmund Freud?</h3>

Sigmund Freud was an Austrian physiologist, neurologist, medical doctor and the founder of psychoanalysis. Also, Freud was born in Moravia on the 6th of May, 1856 and he was famously known around the world for his works on psychoanalytic theory of personality development.

In 1923, Sigmund Freud developed the personality theory through which he strongly argued that a person’s personality (human psyche) is structured into three (3) key parts and these include:

  • The Id (instincts).
  • Ego (reality).
  • Superego (morality).

According to Sigmund Freud, wish fulfillment simply means the satisfaction of a human desire through an involuntary thought process such as dreams. Thus, it typically happens to a person when unconscious desires are adequately repressed by both the ego and superego.

Define longitudinal wave​
Alja [10]

longitudinal wave, wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave. ... Sound moving through air also compresses and rarefies the gas in the direction of travel of the sound wave as they vibrate back and forth.

<u>FORMULA</u>

<h2>y(x,t) = y0 \: cos \: (w(t -  \frac{x}{c} ))</h2>

y = displacement of the point on the traveling sound wave

x = distance the point has traveled from the wave's source

y_0 = amplitude of the oscillations

\omega = angular frequency of the wave

t = time elapsed

c = speed of the wave

What best describes the relationship between wavelength and frequency in an electromagnetic wave? always equal no relationship d
melisa1 [442]

Answer:

Wavelength is inversely proportional to the frequency of wave.

Explanation:

The relationship between wavelength and frequency is inverse. Mathematically, it can be written as :

\lambda=\dfrac{v}{\nu}.......(1)

Where

v is the speed of the wave

\nu is the frequency of wave. It is defined as the number of oscillations per second.

\lambda is the wavelength i.e. it is the distance between two crests or troughs.

So, from equation (1) it is clear that the relationship between frequency and wavelength is inverse.
