A school bus is moving 26.8 m/s on

Physics
1 answer:
Elodia [21]2 years ago
3 0

The time taken for the bus to travel 95.1 m is 2.8 s

<h3>How to determine the final velocity</h3>
  • Initial velocity (u) = 26.8 m/s
  • Acceleration (a) = 4.73 m/s²
  • distance (s) = 95.1 m
  • Final velocity (v) = ?

v² = u² + 2as

v² = 26.8² + (2 × 4.73 × 95.1)

v² = 1617.886

Take the square root of both sides

v² = √1617.886

v = 40.2 m/s

<h3>How to determine the time</h3>
  • Initial velocity (u) = 26.8 m/s
  • Acceleration (a) = 4.73 m/s²
  • Final velocity (v) = 40.2 m/s
  • Time (t) = ?

v = u + at

40.2 = 26.8 + (4.73 × t)

Collect like terms

4.73 × t = 40.2 - 26.8

4.73 × t = 13.4

Divide both side by 4.73

t = 13.4 / 4.73

t = 2.8 s

Which of the following statements describes integrity? A. honesty regulated by a governmental regulatory committee B. honesty as
dolphi86 [110]

The correct answer is C. Honesty regulated by a person’s sense of right and wrong.

Explanation:

Integrity is a personal quality that encompasses moral and ethical correctness that allows an individual to be honest and behave appropriately in different situations and make decisions. This quality is closely related to morals and ethics because these two factors define what is right or wrong, and therefore determine the correct behaviors. Moreover, these factors might vary with the cultural context; for example, if culture emphasizes the importance of respecting the elderly any form of attack to this population would be considered as opposite to integrity. According to this, integrity is "Honesty regulated by a person’s sense of right and wrong."

A rocket moves upward from rest with an acceleration of 40 m/s2 for 5 seconds. It then runs out of fuel and continues to move up
Snezhnost [94]

Answer:

Maximum height of rocket  = 2538.74 m

Explanation:

We have equation of motion s = ut + 0.5 at²

For first 5 seconds

          s = 0 x 5 + 0.5 x 40 x 5² = 500 m

Now let us find out time after 5 seconds rocket move upward.

We have the equation of motion v = u + at

After 5 seconds velocity of rocket

         v = 0 + 40 x 5 = 200 m/s

After 5 seconds the velocity reduces 9.8m/s per second due to gravity.

Time of flying after 5 seconds

          t=\frac{200}{9.81}=20.38s

Distance traveled in this 20.38 s

          s = 200 x 20.38 - 0.5 x 9.81 x 20.38² = 2038.74 m

Maximum height of rocket = 500 +2038.74 = 2538.74 m

Normal conversation has a sound level of about 60 db. How many times more intense must a 100-hz sound be compared to a 1000-hz s
vampirchik [111]

Answer:

5.65 times

Explanation:

60 db sound is equal to 60 phons sound when frequency is kept at 1000Hz.

But when the frequency of sound  is changed to 100 Hz , according to equal loudness curves , the loudness level on phon scale will be 35 phons.

A decrease of 10 phon on phon- scale makes sound 2 times less loud

Therefore a decrease of 25 phons will make loudness less intense by a factor equal to 2²°⁵ or 5.65 less intense . Therefore intensity at 100 Hz

must be increased 5.65 times so that its intensity matches intensity of 60 dB sound at  1000 Hz  frequency.
