<span>Newtons 3rd law of motion states that action and reaction are equal and opposite. How it applies in this statement is that when you jump straight upward you hit the floor and you experience an equal magnitude of force against your feet, because force always acts as a result of two objects and whenever forces occur they do so in pairs of equal magnitude acting in opposite directions. I hope this helps!</span><span>

Answer:
T = 4.42 10⁴ N
Explanation:
this is a problem of standing waves, let's start with the open tube, to calculate the wavelength
λ = 4L / n n = 1, 3, 5, ... (2n-1)
How the third resonance is excited
m = 3
L = 192 cm = 1.92 m
λ = 4 1.92 / 3
λ = 2.56 m
As in the resonant processes, the frequency is maintained until you look for the frequency in this tube, with the speed ratio
v = λ f
f = v / λ
f = 343 / 2.56
f = 133.98 Hz
Now he works with the rope, which oscillates in its second mode m = 2 and has a length of L = 37 cm = 0.37 m
The expression for standing waves on a string is
λ = 2L / n
λ = 2 0.37 / 2
λ = 0.37 m
The speed of the wave is
v = λ f
As we have some resonance processes between the string and the tube the frequency is the same
v = 0.37 133.98
v = 49.57 m / s
Let's use the relationship of the speed of the wave with the properties of the string
v = √ T /μ
T = v² μ
T = 49.57² 18
T = 4.42 10⁴ N
The object is not moving, so the net force acting on it is zero.
The two given forces act in the same direction with a total magnitude of 2 N + 10 N = 12 N.
The third force acts counter to these with some magnitude <em>F</em> to give a net force of 0, so that by Newton's second law
<em>F</em> = 12 N
Answer:
A dicot is a flowering plant that has one seed leaves. The monocot plants have a single cotyledon. Maize only has one cotyledon in their seed, so it's a monocot. Seeds having two Cotyles are mainly called a Dicot. A pea is a dicotyledonous plant, the seed (the pea itself) has two halves, cotyledons, hence dicot being 2.
Explanation:
One or more of the cotyledons are the first to appear from a germinating seed. Based on the number of cotyledons, botanists classify flowering plants (angiosperms) into :
a) plants with one embryonic leaf, termed monocotyledonous (monocots).
b) plants with two embryonic leaves, termed dicotyledonous (dicots).

<h3>What is capitalism?</h3>
The term capitalism means a system in which the means of production is controlled by individuals rather than by the state. Hence, monopoly is possible in a capitalist economy.
