Answer:
mass= 0.1993 kg
Explanation:
Using the formula c = Q / (mΔT)
Answer:
c
Explanation:
The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring.
Answer:
Therefore the amplitude of the resultant wave is 
Explanation:
The equation of wave:
y=A sin (kx-ωt)
For wave 1:
y₁=A sin (kx-ωt) =
sin (kx-ωt)
For wave 2:
y₂=A sin (kx-ωt+Φ) =
sin (kx-ωt+Φ)
Where A= amplitude=
The angular frequency 
,
= wave length.
t= time
T= Time period
= phase difference = 
The resultant wave will be
y = y₁ + y₂
=
sin (kx-ωt) +
sin (kx-ωt+Φ)
{sin (kx-ωt) + sin (kx-ωt+Φ)}



Therefore the amplitude of the resultant wave is



I believe that they are Ice Glaciers.
