Identical objects, Object X and Object Y, are tied together by a string and placed at rest on an incline, as shown in the figure
goblinko [34]

The slope of the velocity time graph of an object moving with constant acceleration is constant

It will take approximately <u>3 seconds</u> for the center of mass of Object X to reach point J near the bottom of the incline

The reason why the above time value is correct is given as follows:

Known parameters:

Initial velocity of the objects, u = 0

The graph  in the question is a straight line graph with data points

(0, 0), (0.5, 1.0), (1.0, 2), (3.0, 6), and (3.5, 7)

Given that the slope of the velocity-time graph is constant, we have that the acceleration is constant and is given as follows;

a = \dfrac{\Delta v}{\Delta t } = \dfrac{v_2 - v_1}{t_2 - t_1}

Therefore;

a =  \dfrac{6 - 2}{3.0 - 1.0} = 2

The acceleration, a ≈ 2 m/s²

The distance from the center of mass of the Object X to the point J near the bottom = 9 m

The equation for distance travelled is given as follows;

s = u\cdot t + \dfrac{1}{2} \cdot a \cdot t^2

Which gives;

9 =  0\times t + \dfrac{1}{2} \times 2 \times t^2 = t^2

t = √9 = 3

The time it will take the center of mass of Object X to reach point J near the bottom of the incline is t = <u>3 seconds</u>

As a clump of interstellar gas contracts to become a main-sequence star, its changing position on the H-R diagram tells us _____
Stels [109]

Answer:

how its outward appearance is changing

Explanation:

H-R diagram is a fundamental tool used to classify stars. The position of stars on the H-R diagram is dependent on its luminosity and temperature.  

The position of the star is represented by its outward appearance specially the color. The hottest and brightest the star, the more it lies between the red and blue color range.  

The cooler stars lie on the right side of the H-R diagram while the hot stars lie on the left side of the H-R diagram.
