<h3><u>Answer;</u></h3>

<em>A mechanical wave transfers energy through matter</em>

<h3><u>Explanation;</u></h3>
  • A<em><u> wave is a transmission of a disturbance </u></em>from one point to another. Wave<u><em> involves transmission of energy from one point to another through a materials medium.</em></u>
  • Waves may require or may nor require a material medium for transmission. Those wave that do not require material medium for transmission are electromagnetic waves while <em><u>those that require material medium are called mechanical waves.</u></em>
  • <u><em>Mechanical waves</em></u> such as sound wave transfers energy from one point which is the wave source to another point through a material medium.

Fiora starts riding her bike at 20 mi/h. after a while, she slows down to 12 mi/h, and maintains that speed for the rest of the
hammer [34]
<span>d = r*t

t = hours at 20 mi/hr


20t + 12*(4.5 - t) = 70
8t = 16
t = 2 hours

d at 20 mi/hr = 20*2 = 40 miles

40/20 + 30/12 = 4.5 hours

Fiora travels a total distance of 4.5 hours</span>

When analyzing a position time graph the direction of the slope positive or negative tells us:
Sphinxa [80]

Answer:

Explanation:

Positive values for position indicate that the object is in front of the starting point and negative values tell us that the object is behind the starting point. (time = 9.5, position = 0) the object is at the starting point.

Which has the most momentum?
boyakko [2]

Answer:

Both objects have the same magnitude of momentum.

Explanation:

If an object of mass m is moving at a velocity of v, the momentum of that object would be m\, v.

The 100\; {\rm g} (0.1\; {\rm kg}) object is moving at a speed of 1\; {\rm m\cdot s^{-1}}. The magnitude of the momentum of this object would be 0.1\; {\rm kg} \times 1\; {\rm m\cdot s^{-1}} = 0.1\; {\rm kg \cdot m \cdot s^{-1}}.

Similarly, the momentum of the 1\; {\rm g} (10^{-3}\; {\rm kg}) object moving at a speed of 100\; {\rm m\cdot s^{-1}} would be 10^{-3}\; {\rm kg} \times 100\; {\rm m\cdot s^{-1}} = 0.1\; {\rm kg \cdot m \cdot s^{-1}}.

Hence, the magnitude of momentum is the same for the two objects.
