Conceptual Analysis

Ribar observed that the use of a conceptual model helps in the understanding of how children get fed and why some go hungry, provides insight into how various programs work, and helps identify potential challenges for program effectiveness. Ribar pointed to the Gundersen discussion in Chapter 2 on the development of conceptual models, to the Institute of Medicine and National Research Council (IOM/NRC) report (2013), and specifically to Barrett’s (2002) model of how household food security is determined. The Barrett model adapted Becker’s (1965) household production model, and is very similar to Grossman’s health production model (1972). Ribar used the Barrett model in his discussion.

The model assumes a household that faces a life-cycle utility function with two objectives in each period. One is to advance its physical wellbeing, and the other is to consume things based on a preference function that incorporates tastes and culture. Finally, the model assumes that the household will discount the future and that the future will be uncertain.

The line graph below shows the number of downloads of two songs after
daser333 [38]

Answer: D

1200

Explanation:

Song 1 is spotted with a cube sign.

At 3 minute, trace the spot to the vertical axis. And you will notice that it a little bit above 10.

Since it is above 10, let assume it is equal to 12.

The number of song downloaded are in hundreds. Therefore, multiply the 12 by 100

12 × 100 = 1200 downloads

Approximately, song 1 has 1200 downloads at minute 3

A 0.560 kg snowball is fired from a cliff 14.2 m high with an initial velocity of 13.3 m/s, directed 26.0° above the horizontal.
enot [183]

Answer:

a) v = 21.34 m/s

b) v = 21.34 m/s

c) v = 21.34 m/s

Explanation:

Mass of the snowball, m = 0.560 kg

Height of the cliff, h = 14.2 m

Initial velocity of the ball, u = 13.3 m/s

θ = 26°

The speed of the slow ball as it reaches the ground, v = ?

The initial Kinetic energy of the snow ball, KE_{0}  = 0.5 mu^{2}

Potential energy of the snow ball at the given height, PE = mgh

Final Kinetic energy of the ball as it reaches the ground, KE_{f} = 0.5mv^{2}

a) Using the principle of energy conservation,

KE_{0} + PE = KE_{f} \\0.5mu^{2} + mgh = 0.5mv^{2}\\v^{2} =2( 0.5u^{2} + gh)\\v^{2} =u^{2} + 2gh\\v = \sqrt{u^{2} + 2gh} \\v = \sqrt{13.3^{2} + 2*9.8*14.2}\\v = 21.34 m/s

b) The speed remains v = 21.34 m/s since it is not a function of the angle of launch

c)The principle of energy conservation used cancels out the mass of the object, therefore the speed is not dependent on mass

v = 21. 34 m/s
