First law: A ball is stationary on the ground. It doesn't want to move, but eventually a person will come and kick it.

Second law: A car will never be constant it will have to stop then go . Objects take time to accelerate and also take time to decelerate.

Third law: If your sitting on a chair at a table, and you want to go, what do you do? Push against the table. The table will push back at you and hence, your chair moves. If this law wouldn't work then you would have to move the chair manually.

Ordinarily, material presented ________ is usually the most difficult to remember due to interference

Brums [2.3K]

Memorizing items on a list are enabled by the effects of primacy and

recency.

Ordinarily, material presented in the middle of a list is usually the most

difficult to remember due to interference.

Reasons:

When memorizing a list of items, due to the primacy effect, the information

at the beginning of the list are given importance, in the brain, due to their

many attributes, which may be due to them being;

The first item

Definition of the task (assignment of importance level)

Idea of what to expect (preparation of the mind)

Also the last items on the list are recalled by the effect known as recency,

which is probably due to the tendency to store items in the short term

memory.

Therefore, in the course of memorizing a list, the first items on the list can

be stored in the long-term memory. The items that comes last in the

list are stored in the short-term memory, while the material presented in

the middle of the list are not allocated to a storage, and are usually

the most difficult to remember due to interference, by other items that

tend to come up during the retrieval process, from the long-term memory.

(Rearranging the list can aid total recall)

An air bubble at the bottom of a lake 36.0 m deep has a volume of 1.22 cm^3. If the temperature at the bottom is 5.9°C and at th

AlexFokin [52]

Answer:

volume of the bubble just before it reaches the surface is 5.71 cm³

Explanation:

given data

depth h = 36 m

volume v2 = 1.22 cm³ = 1.22 × $10^{-6}$ m³

temperature bottom t2 = 5.9°C = 278.9 K

temperature top t1 = 16.0°C = 289 K

to find out

what is the volume of the bubble just before it reaches the surface

solution

we know at top atmospheric pressure is about P1 = $10^{5}$ Pa

so pressure at bottom P2 = pressure at top + ρ×g×h

here ρ is density and h is height and g is 9.8 m/s²

pressure at bottom P2 = $10^{5}$ + 1000 × 9.8 ×36

pressure at bottom P2 =4.52 × $10^{5}$ Pa

so from gas law

$\frac{P1*V1}{t1} = \frac{P2*V2}{t2}$

here p is pressure and v is volume and t is temperature

so put here value and find v1

$\frac{10^{5}*V1}{289} = \frac{4.52*10^{5}*1.22}{278.9}$

V1 = 5.71 cm³

volume of the bubble just before it reaches the surface is 5.71 cm³
