As Douglas considers his wife’s condition, he realizes that the change having the most impact is “the one that began to steal he

r memories”. Why do you think that the loss of Phyllis’s memories is perceived as the most tragic symptom of her illness? Use an example from the story to explain how memories construct individuals, personalities, and day-to-day interactions with others and the way life is lived

I believe that the loss of Phyllis' recollections is thought to be the most heartbreaking side effect of her ailment in light of the fact that once a man's memory scatters then piece of the individual begins to vanish with them. A memory holds a considerable measure of essential data, for example, people's identity, where They have lived, and their connections that they have had with individuals.

How can a large force result in a relatively small power?
Sav [38]

Answer:

hey mate here is your answer

So if an object has a very small velocity (not moving very far over time, even though a large force may be applied to it, the Power will remain small. ... Stepping on the gas, or "speeding up" the car, is applying a force which will increase velocity and increase power.

A 4.0-kg block is pushed up a 36 incline by a force of magnitude P applied parallel to the incline. When P is 31 N, it is obser
denpristay [2]

Answer:

15.1 N

Explanation:

mass of block (m) = 4 kg

angle of inclination = 36 degrees

applied force (P) = 31 N

acceleration due to gravity (g) = 9.8 m/s^{2}

since the block is moving at a constant speed, it means the acceleration is 0 and therefore the summation of all the forces acting on the body is 0

therefore

P - f - mgsinθ = 0

where

  • P = applied force
  • f = frictional force
  • m = mass
  • g = acceleration due to gravity
  • θ = angle of inclination

when P = 31 N and the block is pushed upward

31 - f - (4 x 9.8 x sin 36) = 0

f = 7.96 N

now that we have the value of the frictional force we can find P required to lower the block, our equation becomes p + f - mgsinθ = 0 since the block is to be lowered

P + f - mgsinθ = 0

P = mgsinθ - f

P = (4 x 9.8 x sin 36) - 7.96 = 15.1 N

Bogdan [553]
In a parallel circuit, the total power supply current is the sum of the
currents through all of the individual branches.

The output current (not the voltage) of the power supply is 5 A.
So the individual currents in the circuit branches is 5 A.

The current through the first 2 resistors is (1 + 0.5) = 1.5 A.

So the current through the 3rd resistor is (5 - 1.5) = <u>3.5 A</u>.

A piece of taffy slams into and sticks to another identical piece of taffy that is at rest. The momentum of the two pieces stuck
-Dominant- [34]

Answer:

C. 50%

Explanation:

Lets consider that the mass of taffy is m and its initial velocity is u and final velocity is v. Momentum is conserved so we can write it as,

mu = 2mv\\v = \frac{u}{2} \\

The initial kinetic energy = \frac{mu^{2} }{2}

As the Kinetic energy partly converted into heat.

The final kinetic energy = \frac{m(\frac{u}{2})^{2}  }{2} = \frac{mu^{2} }{4}

Change in the kinetic energy = \frac{mu^{2} }{2} - \frac{mu^{2} }{4} = \frac{mu^{2} }{4}

now we can determine the fraction of kinetic energy that has turned into heat

                           = \frac{Heat energy}{initial K.E} = \frac{\frac{mu^{2} }{4} }{\frac{mu^{2} }{2} }  = 1/2

                           = 50%

If an object falls for 4 seconds, how fast is it going when it hits the ground?
MArishka [77]

Acceleration due to gravity is about 9.8 m/s²

So after every second, the speed increase by 9.8 m/s

After 1 second, the object would fall at a speed of 9.8 m/s

After 2 seconds the object would fall at a speed of 19.6 m/s

So after 4 seconds, the object is going to be at a speed of:

9.8 x 4 = 39.2 m/s

-------------------------------------------------

<u>Answer</u>

39.2 m/s
