How is Behaviorism and Psychoanalysis theories are similar and different?
ser-zykov [4K]
Behaviorism and psychoanalysis are two such schools of thought. Behaviorists give prominence to the external behavior of individuals and believe that behavior is a response to external stimuli. On the other hand, psychoanalysis emphasizes the centrality of the human mind.

While the two theories have been described as polar opposites, two major similarities exist between them. First, the theories are deterministic as they try to explain the factors that result in certain behaviors. Second, both theories acknowledge the important role that experiences play in shaping future behaviors.

Two point charges exert a 6.10 N force on each other. What will the force become if the distance between them is increased by a
anzhelika [568]

Answer:

0.0953125 N

Explanation:

Applying,

F = kq'q/r²................. Equation 1

Where F = electrostatic force, k = coulomb's constant, q' and q = first and second charge respectively, r = distance between the charge.

From the equation,

If both charges remain constant,

Therefore,

F = C/r²

C = Constant =  product of the two charge(q' and q) and k

Fr² = F'r'²................ Equation 2

From the question,

Given: F = 6.10 N

Assume: r = x m, r' = 8x

Substitute these value into equation 2

6.1(x²) = F'(8x)²

F' = 6.1/64

F' = 0.0953125 N

Hence the new force will become 0.0953125 N

A car drives over a hilltop that has a radius of curvature 120 m at the top of the hill. at what speed would the car be travelin
FinnZ [79.3K]
The speed of a car travelling over a hill that has a radius of curvature should not exceed a certain speed other it will topple. This speed is related to the radius of curvature and the gravitational acceleration as shown below:

V^2 = Rg, where V = maximum speed, R = Radius of curvature, g = gravitational acceleration.

Substituting;
V = Sqrt (Rg) =  Sqrt (120*9.81) = 34.31 m/s
