Answer:
4.32
Explanation:
The centripetal acceleration of any object is given as
A(cr) = v²/r, where
A(c) = the centripetal acceleration
v = the linear acceleration
r = the given radius, 1.9 m
Since we are not given directly the centripetal acceleration, we'd be using the value of acceleration due to gravity, 9.8. This means that
9.8 = v²/1.9
v² = 1.9 * 9.8
v² = 18.62
v = √18.62
v = 4.32 m/s
This means that, the minimum speed the cup must have so as not to get wet or any spill is 4.32 m/s
0.345 m.
<h3>Explanation</h3>
The wavelength is the distance that the wave travels in each cycle. The wave travels 345 meters in each second. Let the wavelength of this wave be 
. That's the distance the wave travels in one cycle.
The frequency of the sound wave is 1 000 Hz, meaning that there are 1 000 cycles in each second. The wave travels a distance of 1 000 wavelengths in one second. That would be a distance of 
.
From the speed of the wave, the wave travels 345 meters in one second. In other words,
.
.
To generalize:
,
where
- wavelength of the wave,
the speed of the wave, and
the frequency of the wave.
Answer:
Resultant vector is the sum of two or more vectors
Answer:
From the deepest ocean trench to the tallest mountain, plate tectonics explains the features and movement of Earth's continents/ surface in the present and the past. Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle called convection, the rocky inner layer above the core which has a high density.
Explanation:
Client-centered therapy, Gestalt therapy and Psychoanalysis are all examples of psychotherapy.
<h3>What is therapy?</h3>
Therapy is the process of working as a counselor to develop positive thinking and treat specific mental health conditions like depression or anxiety, trauma. Psycho word is all meant for emotions.
Psychoanalysis, client-centered therapy, Gestalt therapy, rational-emotive therapy, and cognitive-behavior therapy are all examples of psychotherapy.
Thus, Client-centered therapy, Gestalt therapy and Psychoanalysis are all examples of psychotherapy.
