The sound wave produced can be described As a longitudinal wave of constant frequency

Longitudinal waves are waves in which the displacement of the medium is in the same direction as or the opposite direction to , the direction of travel of the wave. In a constant frequency, our brain will acknowledge this wave as 'sound'

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.

A cell membrane consists of an inner and outer wall separated by a distance of approximately 10nm10nm. Assume that the walls act
Mademuasel [1]

Answer:

the correct answue are  B, A, C, C, B

Explanation:

1) The electric field is requested, let's approximate the membrane by a parallel plate with surface charge density

         E = \frac{\sigma }{2 \epsilon_o }

         E = \frac{ 10^{-5}}{2 \ 8.85 \ 10^{-12}}

         E = 5.65 10⁵ N / C

the correct answer is B

2) A calcium ion has two positive charges, so the force applied by each side of the membrane (plate)

         F = q E

         F = 2  1.6 10⁻¹⁹  5.65 10⁵

         F = 1.8 10⁻¹³ N

the total force is the sum of the force of each membrane and the two forces go to the same side

         F = total = 2 F

         F_total = 3.6 10⁻¹³ N

the correct answer is A

3) the field and the electric potential are related

          ΔV = - E s

          ΔV = - 5.65 10⁵  10 10⁻⁹

          ΔV = - 5.65 10⁻³ V

          the correct answer is C

4) In the exercise they indicate that the outer wall has a positive charge, therefore, as they indicate that we approximate the system to a capacitor, the inner wall must be negatively charged.

The electric field goes from the positive to the negative charge, which is why it goes from the outer wall to the inner wall

the correct answer is C

5) For this part we use conservation of energy

starting point. On the inside wall, brown

            Em₀ = U = qV

final point. On the outside

             Em_f = K

energy is conserved

           Em₀ = Em_f

           q V = K

            K = 3 10⁻¹⁵  5.65 10⁻³

            K = 1.7 10⁻¹⁷ J

the correct answer is B

it would not be safe to connect the electric cooker hob to the mains electricity supply by plugging it into a standard power soc
zvonat [6]

Answer:

Switches in mains circuits should always be included in the live wire so that when the switch is open no electrical energy can reach an appliance. If the switch is included in the neutral wire, electrical energy can still enter an appliance, and could possibly cause an electric shock (Figure 7.10).

A man has a mass of 70kg. Calculate his weight on earth where the gravitational strength is 10 N/kg​
maw [93]

Answer:

So the weight of the body is 700N

Explanation:

mass of the object=70kg

force of gravity=10N/kg

weight of the object=w-?

as we know that

weight=mass × force of gravity

weight=70kg × 10N/kg

WEIGHT OF THE BODY=700N

I HOPE IT WILL HELP YOU

GOOD LUCK FOR THE ASSIGNMENT
