One mole of an ideal gas expands isothermally from 0.01 m3 to 0.05 m3. The final pressure of gas is 1.2 atm. [15 Marks] determin
erik [133]

Answer:

Initial pressure = 6 atm. Work = 0.144 J

Explanation:

You need to know the equation P1*V1=P2*V2, where P1 is the initial pressure, V1 is the initial volume, and P2 and V2 are the final pressure and volume respectively. So you can rearrange the terms and find that (1.2*0.05)/(0.01) = initial pressure = 6 atm. The work done by the system can be obtained calculating the are under the curve, so it is 0.144J

A 120 V potential difference is applied to a space heater that dissipates 674 W during operation. (a) What is its resistance dur
Annette [7]

Answer:

(a) 21.36 ohms

(b) 5.62 A

Explanation:

Parameters given:

Potential difference, V = 120 V

Power, P = 674 W

(a) Power is given as:

P = V²/R

Where R is resistance

=> R = V²/P

R = 120²/674

R = 14400/674

R = 21.36 ohms

(b) Power is also given as:

P = I*V

Where I = Current (time rate of flow of Electric charge)

=> I = P/V

I = 674/120

I = 5.62 A

A baseball is launched horizontally from a height of 1.8 m. The baseball travels 0.5 m before hitting the ground. How fast is th
zysi [14]

Answer:

0.83 m/s

Explanation:

FIrst of all, we have to find the time of flight, i.e. the time the baseball needs to reach the ground. This can be done by using the equation for the vertical motion:

h=ut+\frac{1}{2}gt^2

where

h is the initial height

u = 0 is the initial vertical velocity

g = 9.8 m/s^2 is the acceleration of gravity

t is the time

Substituting h = 1.8 m and solving for t,

t=\sqrt{\frac{2h}{g}}=\sqrt{\frac{2(1.8)}{9.8}}=0.61 s

We know that the horizontal distance travelled by the ball is

d = 0.5 m

Therefore, we can find the horizontal velocity (which is constant during the whole motion):

v= \frac{d}{t}=\frac{0.5}{0.60}=0.83 m/s

Answer:

The Baltes' model of successful aging and its considerations for Aging Life Care

Explanation:

Baltes theory of successful aging – usually referred to as the SOC (selection, optimization, compensation) model. This model seemed to say that the old school of thought – disengagement – could be replaced by actively pursuing the means to make any specific situation better.

The selection, optimization and compensation (SOC) model, first presented by Baltes and Baltes (1990), provides a general theory for conceptualizing processes of successful development generally and in aging in particular (S.-C. Li & Freund, 2005). The meta-model of SOC evaluates cognitive-motivational processes regulating human development across the life span and was originally designed and developed as an explanatory framework for adaptation to aging.

The key concept of SOC describes a general process of adaptation that individuals are likely to engage in throughout life and is essential for the achievement of higher levels of functioning (P. B. Baltes & Baltes, 1990). The model takes the global view that at all stages of human development individuals manage their lives successfully through the developmental regulation processes of selection, optimization, and compensation. Successful development involves the orchestration of these three processes (selection, optimization, and compensation) which in turn, regulate the maximization of gains and minimization of losses over time. Selection, optimization, and compensation can be conceived of as one single “integrative” process of adaptive mastery and also on a lower or more micro level of aggregation, the facets of SOC can be viewed as separate processes, each contributing to successful development (Freund & Baltes, 1998b).

Selection refers to an individual focusing attention on fewer, more important goals e.g. rescaling/reconstructing goals. Optimization involves engaging in goal-directed actions and means; examples include investing time and energy into the acquisition, refinement and application of goal-relevant means, seizing the right moment, persistence, acquisition of new skills/resources, and practice of skills.

Compensation maintains a given level of functioning in the face of loss and decline in goal-relevant means by individuals investing in compensatory means.
