Explanation:
The net force along the horizontal direction is
where f is the frictional force. We can find the frictional force by looking at the vertical forces acting on the couch:
From the definition of frictional force,
Therefore, the net force on the couch is
Answer:
Nodes = 5 and antinodes = 4
Explanation:
Nodes are the points of zero amplitude and appear to be fixed. On the other hand, antinodes are points on a stationary wave that oscillates with maximum amplitude.
In this given standing wave, there are 5 points where the amplitude is 0. So, there are 5 nodes. Also, there are 4 points where the amplitude is maximum.
So, there are 5 nodes and 4 antinodes.
Answer:
8.19m
Explanation:
Parameters given:
Pressure, P= 11.6 psi = 79979.185 Pa
Gauge pressure is given as:
P = h*d*g
=> h = P/(d*g)
Where
h = height of tank
d = density
g = acceleration due to gravity
Density of water = 997 kg/m³
Therefore, the height of the tank is:
h = 79979.185/(997 * 9.8)
h = 8.19m
Answer:
since each loop is ewuvivalent to one half wave lenght . the length of the string is equal to two halves of a wavelength . put in the form of an equation in the same reasoning also
