In a completely inelastic collision, the two objects stick together after the collision.
Semenov [28]3 years ago
3 0
<h3><u>Answer;</u></h3>

A. Stick and move together

<h3><u>Explanation;</u></h3>
  • <u><em>A perfect inelastic collision is a type of collision in which in which part of kinetic energy is converted to other form of energy during the collision.</em></u>
  • In an elastic collision on the other hand, is a type of collision in which both conservation of momentum and conservation of kinetic energy are observed.
  • <em><u>During perfectly inelastic collision, the objects or bodies involved stick together and move as a single object after the collision.</u></em> These type of collisions result to in loss of maximum kinetic energy, which is converted into heat or in the work done in deforming the objects involved.

A boy is listening to the radio. The loudspeaker plays a musical note by vibrating 256 rimes esch second. How many times does th
Svet_ta [14]

Answer:

 f_tympanum = 256 Hz.

Explanation:

The eardrum is the vibrating membrane of the human ear, it works by resonance, that is, an external stimulus (force) makes it vibrate, as the eardrum is extremely light it can vibrate at the same frequency of the incident sound.

Consequently if the incident vibration is f = 256 hz, the eardrum resonates at the same frequency

            f_tympanum = 256 Hz.

As a reference the response of the eardrum goes from f = 20 Hz f = 20000 Hz

It took Eric 11 hours to drive to a football game. On the way home, he was able to increase his average speed by 12mph and make
yarga [219]

Answer:

54mph

Explanation:

Speed is defined as the change in distance of a body with respect to time.

Let x be the speed of Eric on his way to the football game, if he used 11hours to the football game, his distance will be the product of his speed and time taken i.e

Distance = speed × time

Distance= x × 11

Distance = 11x... (1)

During his return journey, his speed increases by 12mph with a return drive in only 9hours i.e speed = x+12 and time is 9hours

Since distance = speed × time (return Journey)

Distance = (x+12)×9

Distance = 9x+84...(2)

Note that the distance to and fro the journey is the same as such we will equate equations 1 and 2 to get his initial speed "x" to have;

11x = 9x+84

11x-9x = 84

2x = 84

x = 42mph

This means that his initial speed on his way to the football game is 42mph. Since his speed increases by 12mph during his return drive, his return speed will be 42mph + 12mph which gives 54mph.
