Answer: E = 5.80*10^-13 J
Explanation:
Given
We use the law of conservation of momentum to solve this
Momentum before breakup = momentum after breakup
0 = m1v1 + m2v2
0 = 238m * -2.2*10^5 + 4m * v2
0 = -523.6m m/s + 4m * v2
v2 * 4m = 523.6m m/s
v2 = 523.6 m m/s / 4m
v2 = 130.9*10^5 m/s
v2 = 1.31*10^7 m/s
Using this speed in the energy equation, we have
E = 1/2m1v1² + 1/2m2v2²
E = 1/2 * (238 * 1.66*10^-27) * -2.2*10^5² + 1/2 * (4 * 1.66*10^-27) * 1.31*10^7²
E = [1/2 * 3.95*10^-25 * 4.84*10^10] + [1/2 * 6.64*10^-27 * 1.716*10^14]
E = (1/2 * 1.911*10^-14) + (1/2 * 1.139*10^-12)
E = 9.56*10^-15 + 5.7*10^-13
E = 5.80*10^-13 J

Answer:
- Problem-recognition.
Explanation:
The consumer decision-making process is associated with the process of consumers recognizing their needs and requirements, collecting information followed by the evaluation of distinct alternatives available in the market and then finally reaching a decision to opt for a specific product to buy.
As per the given description, Gilbert's evaluation of his need that his current phone is not able to meet up his requirement and realization that he requires a phone with a longer-battery life exemplifies that he is in the '<u>problem-recognition</u>' phase of the consumer decision-making process. This stage would be followed by the assessment of alternatives(various phones with longer battery life) and reaching the conclusion to buy a specific chosen product after the evaluation.
