Explanation:
In the study of personality, the Five-factor model includes different traits that underlie one’s basic tendencies.
<h3>What is the Five-factor model?</h3>
The Five-factor model is a scientific theory that states traits of the personality of an individual are due to its biology and therefore they respond to adaptations, which are central in the biology field.
In conclusion, in the study of personality, the Five-factor model includes different traits that underlie one’s basic tendencies.

Answer:
Increase
Explanation:
q = Charge in the potassium ion = 
e = Charge of electron = 
= Change in potential = 
Change in electric potential is given by
The energy is
The potential energy will increase.
Answer:
Initial velocity of the object, u = 5 m/s
Final velocity of the object, v = 8 m/s
Mass of the object, m = 100 kg
Time take by the object to accelerate, t = 6 s
Initial momentum = mu = 100 — 5 = 500 kg m sˆ’1
Final momentum = mv = 100 — 8 = 800 kg m sˆ’1
Force exerted on the object, F = mv – mu / t
= m (v-u) / t
= 800 – 500
= 300 / 6
= 50 N
Initial momentum of the object is 500 kg m sˆ’1.
Final momentum of the object is 800 kg m sˆ’1.
Force exerted on the object is 50 N.

Answer:
Explanation:
Height attained by body = 50 cm
= .5 m
Initial velocity = u
v² = u² - 2gh
0 = u² - 2gh
u² = 2 x 9.8 x .5
u = 3.13 m /s
During the initial period , the muscle stretches by around 10 cm during which force by ground reacts on the body and gives acceleration to achieve velocity of 3.13 m/s from zero .
v² = u² + 2as
3.13² = 0 + 2 a x .10
a = 49 m/s²
reaction by ground R
Net force
R-mg = ma
R= m ( g +a )
= mg + ma
=W + (W/g) x a
W ( 1 + a / g )
= W ( 1 + 49 / 9.8 )
= 6W
