Work = Force x displacement
Force= 20N
Displacement= 0.75m
W= 20(0.75)
W= 15 Nm
Answer:
Horizontal distance from the foot of the cliff is 40 m
Explanation:
Given :
Speed of stone 
Vertical distance
m
Gravitational acceleration

From the kinematics equation,

Where
initial velocity (
)
So time take to fall down,


sec
Now find horizontal distance travel by stone,


m
Therefore, the horizontal distance travel by stone is 40 m
Personality theorists often focus on differences in individuals.
Answer: Option A
<u>Explanation:
</u>
According to the personality psychology, personality scientists study personality and its variations amongst the individuals. They often focus on the thoughts, judgements and social behaviour of the individuals that they exhibit over time.
