Answer:

The formula for speed is speed=<u>d</u><u>i</u><u>s</u><u>t</u><u>a</u><u>n</u><u>c</u><u>e</u>

time

Explanation:

to work out what the units are for speed,you need to know the units for distance and time.In this example,distance is in metres(m) and time is in seconds (s) , so the units for speed is metre per second (m/s).

What is the molality of a solution that contains 54 grams of NaOH dissolved in 1.50 kg of water? (The molar mass of NaOH 40.00 g
expeople1 [14]

Answer:

0.900 mol/kg

Explanation:

Molality is moles of solute per kilograms of solvent.

Converting 54 grams of NaOH to moles:

54 g NaOH × (1 mol NaOH / 40.00 g NaOH) = 1.35 mol NaOH

So the molality is:

m = (1.35 mol) / (1.50 kg)

m = 0.900 mol/kg

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 <u>in the middle of a list </u> 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.

<em>(Rearranging the list can aid total recall)</em>

We can model the motion of a bumblebee's wing as simple harmonic motion. A bee beats its wings 250 times per second, and the win
zlopas [31]

Answer:

The amplitude of the wing tip's motion is 1.6 mm.

Explanation:

Given that,

Beat = 250 /s

Speed = 2.5 m/s

We need to calculate the amplitude of the wing tip's motion

Using the equation for the maximum velocity

v_{max}=2\pi f A

A=\dfrac{v}{2\pi f}

Where,

v = speed

f = frequency

A = amplitude

Put the value into the formula

A=\dfrac{2.5}{2\pi\times250}

A=0.00159 = 1.59\times10^{-3}\ m

A=1.6\ mm

Hence, The amplitude of the wing tip's motion is 1.6 mm.
