Answer:

The correct answer is option D.

Explanation:

Acoustic : A branch of physics which study the properties of sound.

Consonance: Combination of notes occurring simultaneously due to relationship between their respective frequencies.

Timbre: A characteristic of a musical note which makes it distinct from another wave which also have same pitch and intensity.

Dissonance :When combination of two notes are played simultaneously with lack of harmony in between them.

Hence, the correct answer is option D.

Answer:

a) Team A will win.

b) The losing team will accelerate towards the middle line with 0.01 m/s^{2}

Explanation:

Given that Team-A pulls with a force , F_{1} = 50N

and Team-B pulls with a force , F_{1} = 45N

∵ F_{1} > F_{2}

The rope will move in the direction of force F_{1}.

∴ Team-A will win.

b) Considering both the teams as one system of total mass , m = 246+253 = 499 kg

Net force on the system , F = F_{1} - F_{2} = 50-45 = 5N

Applying Newtons first law to the system ,

F = ma , where 'a' is the acceleration of the system.

Since , both the teams are connected by the same rope , their acceleration would be the same.

∴ 5 = 499×a

∴ a = 0.01 m/s^{2}

Two soccer players kick the same 2-kg ball at the same time in opposite directions one kicks with a force of 15 n the other kick
Illusion [34]
Because the direction of the kicks are opposite, the net force between the applied forces is their difference.
                        Fn = F₂ - F₁
Substituting,
                        Fn = 15 N - 5 N
                        Fn = 10 N

From Newton's second law of motion,
                       Fn = m x a
where m is mass and a is acceleration. Manipulating the equation so that we are able to calculate for a,
                       a = Fn / m

Substituting,
                      a = (10 N) / 2 kg
                       a = 5 m/s²

<em>ANSWER: 5 m/s²</em>
