Please see the complete question below.
Hart volunteers with Habitat for Humanity. When he is at a work site, he is so engrossed in activity that he loses all sense of time and self-awareness. Hart is experiencing
A. early-onset dementia.
B. environmental mastery.
C. self-efficacy.
D. flow.
Answer:
The answer is flow (Option D)
Explanation:
An individual experiences a flow state in work when the mental state of the individual performing the work or activity is fully invested in the work such that he or she enjoys it and loses track of time.
This kind of state is also known as "being in the zone". Individuals in flow state like Hart (in the question) have energized focus when working on a particular project or getting a job done such that they also lose self-awareness.
Answer:
10 m/s/s or m/s²
Explanation:
Acceleration can be calculated by using the formula;
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
In other terms, acceleration (a) can be represented as ∆V/t.
According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:
a = 30 - 10/2
a = 20/2
a = 10m/s².
