Answer:
Explanation:
The fundamental mode of the standing wave in string is expressed as;
fo
F = V/2L where;
V is the speed of the transverse wave
L is the length of the string
Given
V = 40.0m/s
L = 2.00m
F = 40.0/2(2)
F = 40/4
F = 10Hertz
Hence the fundamental mode of the standing wave is 10Hz
<em></em>
<em>Overtone/harmonics are integral multiples of the fundamental frequency.</em>
Note that 1st overtone is also called second harmonic
Second harmonic
First overtone F1 = 2F
Second overtone/Third harmonics = 3F
First overtone F1 = 2*10
First overtone = 20Hz
3rd harmonic = 3*10
3rd harmonic = 30Hz
Answer:
The situation given in option A and B are examples for moving an object toward left side while the option C and option D are examples for moving an object toward right side. Option B will also be an example for not moving the object.
Explanation:
As per the option A statement, the force acting towards left is greater than the force acting toward right side. So the net force will be towards the direction having maximum magnitude. Thus, the box will move toward left side in option A. The same situation arises for the object in option B. But here the difference in the forces is only 1 N, so the change in the position of the object will be very less. Thus it may look like there is no acceleration in the box of option B.
Similarly, the force acting on the objects given in option C and D have magnitude greater towards the right side than towards the left side. So these two will be accelerated toward the right side.

Answer:
The correct answer is - distress.
Explanation:
Eustress is a type of stress that is beneficial to person and caused by adrenaline. Hypostress is a stress that is caused due to boredom or no work. It is stress comes with wasting the time.
Distress is the bad stress caused by anxiety, sadness, grief, and such type of stress that is caused irritability. Irritability is caused not just by stress but many factors.
