Answer:

In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.

Sound waves because sound waves use sound to travel and vibration is also a sound so therefore is sound waves

With what initial velocity must an object be thrown upward from a height of 2 meters to reach a maximum hieght of 200 meters

larisa86 [58]

The equations of motion to use for a constant acceleration a = g = -9.81:
$v = gt + v_0$
$y = \frac{1}{2} g t^{2} + v_0t + y_0$

at the highest point the velocity must be zero:
$0 = gt + v_0 \\ v_0 = -gt$
combine both equations:
$y = \frac{1}{2} \frac{v_0^{2} }{g} - \frac{v_0^{2} }{g} + y_0= -\frac{1}{2} \frac{v_0^{2} }{g} + y_0$
Solve for v₀:
$v_0 = \sqrt{2g(y_0 - y)}$

A dump truck and a little toy matchbox car have the same velocity. which one has the greater momentum?

Zina [86]

That would be the dump truck. Momentum depends on how heavy a certain object is in motion. The more weight it has the harder it is to stop.

Sound waves need a medium to move through in order to keep moving. Through which of the following would sound travel the slowest

Troyanec [42]

Answer:A air

Explanation:Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.
