<span>the transverse wve that requires a medium to move is : sound waves
in order to travel, sound waves need to jumped on between one particle to another, no matter it's liquid, solid , and gases. Which explains why you wont hear a thing in outer space, simply because the sound waves got no particle to jumped into</span>
The reflected ray is rotated through 12°.
<h3 /><h3>What is reflection?</h3>
Freflection can be defined as the turning back of a ray of light when its strikes a plane's surface.
There are 2 laws of reflection
<h3>Laws of reflection</h3>
(1) The first law of reflection states that the incident ray the reflected ray and the normal all at the point of incidence lie in the same plane
(2) The second law of reflection states that the angle of incident is equal to the angle of reflection.
From the question, if the incidence ray is rotated through 6°, then the reflected ray is rotated through 12°
Hence, The reflected ray is rotated through 12°.
2pi x (3/4) = 3 pi /2
as we knw that
1: 45 min --> 105 s
<span>so the</span>
<span>rate = d/t = 3pi / 2 / 105 s = pi /70 rad/s
hope it helps</span>
Answer:
448 J/kg/°C
Explanation:
m₁ C₁ (T₁ − T) + m₂ C₂ (T₂ − T) = 0
(0.0414 kg) C (243°C − 20.4°C) + (0.411 kg) (4186 J/kg/°C) (18°C − 20.4°C) = 0
(9.22 kg°C) C − 4129 J = 0
C = 448 J/kg/°C
