Physics

Answer:

See explanation

Explanation:

1) There are two main types of waves;

Mechanical waves and electromagnetic waves.

Mechanical waves usually require a medium for propagation, e.g sound, waves on a spiral spring, etc

Electromagnetic waves do not require a medium for propagation e.g microwaves, x-rays etc

2) The phenomenon is known as refraction. Refraction occurs at the boundary between two media because of the change in the speed of a wave as it moves from one medium to another.

Explain how sound is being produced from this 'Stomp' group.
Ira Lisetskai [31]

Answer:

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.

In many ways, sound waves are similar to light waves. They both originate from a definite source and can be distributed or scattered using various means. Unlike light, sound waves can only travel through a medium, such as air, glass, or metal. This means there’s no sound in space!

the jamaican bobsled team hit the brakes on their sled so that it decelerates at a uniform rate of 0.43 m/s, how long does it ta
IceJOKER [234]
 <span>here's a cheap trick 
it would take the same time to accelerate from rest to top speed 
as it would take to decelerate from top speed to zero 
so 
instead of 
d = Vi t + 1/2 a t^2 where Vi is positive and a is negative 
we'll use 
Vi = 0 and a is positive 
giving 
85 = 0 + 1/2 (0.43) t^2 = 0.215 t^2 
t^2 = 395.345 
t = 19.88s or 20. s to 2 sig figs 

or we ccould find Vi from 
Vf*2 = Vi^2 + 2 a d 
0 = Vi^2 + 2 (0.43) 85 
Vi^2 = 71.4 
Vi = 8.45m/s 
then 
85 = 8.45 t + 1/2 (-0.43) t^2 
85 = 8.45 t - 0.215 t^2 
0.215 t^2 - 8.45 + 85 = 0 
t = 19.65s or 20. s to 2 s.f.(minor difference arises from rounding Vi) 
or another cheap trick 
when a is constant 
Vavg = (Vf + Vi) /2 = 8.45/2 = 4.225 
and 
d = Vavg t 
85 = 4.225 t 
t = 20.12 or 20. s to 2 s.f. (minor differences from intermidiate roundings) 

anyway you choose you get 20. s</span>
