Answer:
Force constant will be 1195.85 N/m
Work done will be 1.6859 J
Explanation:
We have given the force, F = 63.5 N
Spring is stretched by 5.31 cm
So x = 0.0531 m
Force is given , F = 63.5 N
We know that force is given by 
So 
k = 1195.85 N/m
Now we have to find the work done
We know that work done is given by
Answer: If the forces on an object are balanced, the net force is zero. If the forces are unbalanced forces, the effects don't cancel each other. Any time the forces acting on an object are unbalanced, the net force is not zero, and the motion of the object changes.
Answer:
A. Close to 14 is considered a strong base
Explanation:
A substance with a pH close to 14 is considered a strong base

Answer:
v=39.05 m/s
Explanation:
Given that
x= 56 cm
F= 158 N
m= 58 g = 0.058 kg
Lets take spring constant = k
At the initial position,before releasing the arrow
F= k x
By putting the values
F= k x
158= 0.56 k
k=282.14 N/m
Now from energy conservation
Lets take final speed of the arrow after releasing
k x²=mv²
282.14 x 0.56² = 0.058 v²
v=39.05 m/s
Answer:
A) attachment.
Explanation:
The psychiatrist and psychoanalyst John Bowlby (1907 - 1990) believed that the causes of mental health and behavioral problems could be attributed to early childhood. In fact, John Bowlby's <u>attachment theory states that we have been biologically preprogrammed to build bonds with others and that they help us survive.
</u>
Bowlby was greatly influenced by ethological theory in general, but above all by Konrad Lorenz's study of the imprint done with ducks and geese in the 50s. From this, Lorenz demonstrated the survival value of the attachment bond by Your innate character
Thus, Bowlby thought that attachment behaviors were instinctive and that, in addition, their activation depended on any condition that could threaten the achievement of proximity, such as separation, insecurity or fear.
John Bowlby's attachment theory defends that children are biologically programmed to form bonds with others.
