How do expectations relate to future schooling?

Snezhnost [94]

Expectations relate to future schooling by choosing classes that are at your skill level.

Answer: Option B

<u>Explanation: </u>

Each individual has a different set of skills blessed by the Mighty and each should enhance them according to his/her will and interest. For the future prospects of schooling and teaching, there is one noticeable point to be acted is that students should not be forced to study the subject beyond their skills and capability.

We should remember that a fish cannot fly and a bird cannot swim. They both cannot be trained under the same study programmes. Although they both can know how to swim and fly but it’s their capability and interest over the subjects that can lead them further to rule over either the sky or the oceans.

So, the future school programming should be done in such a way that individuals have an authority to choose their subjects accordingly and learn more about their skills.

you are designing an airport for small planes. one kind of airplane that might use this airfield must reach a speed before takeo

denis23 [38]

(a)The required speed for take off will be 24.49 m/sec.

(b)The minimum length must the runway have 193 m.

<h3>What is speed?
</h3>

Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. it is denoted by u for the initial speed while v for the final speed. its SI unit is m/sec.

(a)The required speed for take off will be 24.49 m/sec.

From the Newtons third equation of motion;

$\rm v^2 = u^2+2as \\\\ v=0+2 \times 2 \times 150 \\\\ v=\sqrt{600}\\\\ v=24.49 \ m/sec$

Hence, the required speed for take off will be 24.49 m/sec.

(b)The minimum length must the runway have 193 m.

From the Newtons third equation of motion;

$\rm v^2 = u^2+2as \\\\ (27.78)^2 = 0+2\times 2 s \\\\\ s=192.93 \ m$

Hence, the minimum length must the runway have 193 m.

A rabbit is traveling at a steady 6 m/s and (without knowing it) passes a wolf. The wolf takes off at the instant the rabbit pas

Katena32 [7]

Answer:

It takes the wolf 3 s to move as fast as the rabbit.

The wolf is 9 m from the rabbit when it reaches a speed of 6 m/s

Explanation:

The equations for the position and velocity of objects moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position of the object at time t

x0 = initial position of the object

t = time

v0 = initial speed

a = acceleration

v = velocity of the object at time t

For the first question, let´s use the equation of velocity of the wolf to find at which time its velocity is the same as the velocity of the rabbit ( 6 m/s):

v = v0 + a · t (v0 = 0 because the wolf starts at rest)

6 m/s = 0 + 2.0 m/s² · t

t = 3 s

Now, with this calculated time, let´s obtain the position of the wolf:

x = x0 + v0 · t + 1/2 · a · t² (Placing the center of the frame of reference at the point when the wolf starts running makes x0 = 0)

x = 1/2 · a · t²

x = 1/2 · 2.0 m/s² · (3 s)²

x = 9 m

Now, let´s calculate the position of the rabbit. Notice that a = 0. Then:

x = x0 + v · t x0 = 0

x = v · t

x = 6 m/s · 3 s = 18 m

The wolf is (18 m - 9 m) 9 m from the rabbit when it reaches a speed of 6 m/s
