Two identical small charged spheres are a certain distance apart, and each one initially experiences an electrostatic force of m
monitta

Answer:

1/4F

Explanation:

We already know thatThe electrostatic force is directly proportional to the product of the charge, from Coulomb's law.

So F α Qq

But if it is now half the initial charges, then

F α (1/2)Q *(1/2)q

F α (1/4)Qq

Thus the resultant charges are each halved is (1/4) and the first initial force experienced at full charge.

Thus the answer will be 1/4F

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.

How much heat is absorbed by a 66g iron skillet when its temperature rises from 7oC to 20oC?
fenix001 [56]
The heat absorbed is calculated using the following equation:
Q = mCΔT

Q = heat absorbed
m = mass = 66 g
C = specific heat of iron = 0.449 J/g.°C
ΔT = temperature change = 20 - 7 =13°C

Therefore,
Q = 66*0.449*13 = 385.242 J
