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

A. Are created by vibrations

<h3><u>Explanation;</u></h3>

<em><u>Mechanical waves are waves which travel only through matter and involve the motion and vibration of particles of the matter they pass through. Sound waves are an example.</u></em>
Sound waves are longitudinal waves. Speed of sound is about 343 m/s (767 mi/h) in sea-level air at ordinary temperatures. Additionally, sound travels faster in liquids and solids than in gases.

A car with a mass of 600 kg is traveling at a velocity of 10 m/s. How much kinetic energy does it have?

vaieri [72.5K]

Answer:

30000 J = 30 kJ

Explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K.E. of an object using the equation,

K.E. = $\frac{1}{2} mv^{2}$

So you get,

K.E. = $\frac{1}{2} 600×10^{2}$

= 30000 J = 30 kJ

Using an example, explain how small atoms are.

Aliun [14]

Unlike a ball, an atom doesn't have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance... Does that answer your question?

Determine the slope of end a of the cantilevered beam. E = 200 gpa and i = 65. 0(106) mm4

DENIUS [597]

For E = 200 gpa and i = 65. 0(106) mm4, the slope of end a of the cantilevered beam is mathematically given as

A=0.0048rads

<h3>What is the slope of end a of the cantilevered beam?</h3>

Generally, the equation for the is mathematically given as

$A=\frac{PL^2}{2EI}+\frac{ML}{EI}$

Therefore

A=\frac{10+10^2+3^2}{2*240*10^9*65*10^6}+\frac{10+10^3*3}{240*10^9*65*10^{-6}}

A=0.00288+0.00192=0.0048rads

A=0.0048rads

In conclusion, the slope is

A=0.0048rads
