The answer is directed northward. The acceleration will be negative, since the car is decelerating. Thus the power that is slowing it down must be performing in the opposite direction to that which the car is traveling. Or in other words, when speed is lessening, acceleration is in the opposed direction to velocity. The change is CONTRASTING the velocity and so it slows it down.

Which of the following statements describes integrity? A. honesty regulated by a governmental regulatory committee B. honesty as
dolphi86 [110]

The correct answer is C. Honesty regulated by a person’s sense of right and wrong.

Explanation:

Integrity is a personal quality that encompasses moral and ethical correctness that allows an individual to be honest and behave appropriately in different situations and make decisions. This quality is closely related to morals and ethics because these two factors define what is right or wrong, and therefore determine the correct behaviors. Moreover, these factors might vary with the cultural context; for example, if culture emphasizes the importance of respecting the elderly any form of attack to this population would be considered as opposite to integrity. According to this, integrity is "Honesty regulated by a person’s sense of right and wrong."

One of these cars is black and the other is red (really). They are illuminated by sodium lamps which have dominantly yellow ligh
nekit [7.7K]

The two cars illuminated by sodium lamps appear black because the red and black colours are absorbed and no colour is reflected.

<h3>What is reflection of light?</h3>

Reflection of light is the ability of light rays to bounce back off a surface when they are incident on that surface

The ability of light to be reflected gives rise to changes in the colour of objects

When light is incident on a surface, the colour that is reflected gives the colour of that object.

Therefore, when two cars of red and black colur are illuminated by sodium lamps, they appear black because the red and black colours are absorbed and no colour is reflected.

Two spheres having masses M and 2M and radii R and 3R, respectively, are released from rest when the distance between their cent
Andrei [34K]

Answer:

v_2 = \sqrt{\frac{GM}{3R}}

v_1 = 2\sqrt{\frac{GM}{3R}}

Explanation:

As we know by energy conservation that change in gravitational potential energy of the system = change in kinetic energy of the two ball

So here we can say

-\frac{GM(2M)}{12R} + 0 = -\frac{GM(2M)}{4R} + \frac{1}{2}Mv_1^2 + \frac{1}{2}(2M)v_2^2

Also since there is no external force on the system of two masses so here total momentum of the two balls will remains conserved

0 = Mv_1 + 2Mv_2

v_1 = -2v_2

now we have

\frac{GM^2}{2R} - \frac{GM^2}{6R} = \frac{1}{2}M(-2v_2)^2 + \frac{1}{2}(2M)v_2^2

\frac{GM^2}{3R} = Mv_2^2

v_2 = \sqrt{\frac{GM}{3R}}

v_1 = 2\sqrt{\frac{GM}{3R}}
