A 12.0N force with a fixed orientation does work on a
kvasek [131]

Answer:

(a) \theta=62.31^{\circ}

(b) \theta=117.68^{\circ}

Explanation:

It is given that,

Force acting on the particle, F = 12 N

Displacement of the particle, d=(2.00i -4.00j+3.00k)\ m

Magnitude of displacement, d=\sqrt{2^2+4^2+3^2}= 5.38\ m

(a) If the change in the kinetic energy of the particle is +30 J. The work done by the particle is given by :

W=Fd\ cos\theta

\theta is the angle between force and the displacement

According to work energy theorem, the charge in kinetic energy of the particle is equal to the work done.

So,

cos\theta=\dfrac{W}{Fd}

cos\theta=\dfrac{+30\ J}{12\times 5.38}

\theta=62.31^{\circ}

(b) If the change in the kinetic energy of the particle is (-30) J. The work done by the particle is given by :

cos\theta=\dfrac{W}{Fd}

cos\theta=\dfrac{-30\ J}{12\times 5.38}

\theta=117.68^{\circ}

Hence, this is the required solution.

1.How far is Object Z from the origin at t = 3 seconds?
GenaCL600 [577]

Answer:

Please find the answer in the explanation

Explanation:

1.) How far is Object Z from the origin at t = 3 seconds

The distance of the object Z from the origin will be the slope of the graph.

Slope = 4/2 = 2m

2.) Which object takes the least time to reach a position 4 meters from the origin ?

According to the graph given to the question above, object Z has the list time which is 2 seconds since object X does not start from the origin.

3.) Which object is farthest from the origin at t = 2 seconds?

The correct answer is still object Z because it has the highest slope.

Why do astronomers believe that triton is a captured moon?
Dafna11 [192]

Answer: Accoding to research "Triton is unique among all the large moons in the solar system because it orbits Neptune in a direction opposite to the planet's rotation (a "retrograde" orbit). It is unlikely to have formed in this configuration and was probably captured from elsewhere."
