Answer:
The speed of light becomes slower in denser medium which is water in this case.
Explanation:
We know the lens law of Refraction which states
Refractive index of second medium /Refractive index of the first medium
= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)
When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.
When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.
Answer:
0.94 L
Explanation:
Step 1: Write the balanced reaction
2 Al + 3 Br₂ = 2 AlBr₃
Step 2: Calculate the moles of Br₂ required to produce 12 moles of AlBr₃
The molar ratio of Br₂ to AlBr₃ is 3:2. Then,
Step 3: Calculate the mass of bromine corresponding to 18 moles
The molar mass of bromine is 159.81 g/mol. Then,
Step 4: Calculate the volume of bromine corresponding to 2.9 × 10³ g
The density of bromine is 3.1 g/mL. The volume of bromine is:
Answer:
= 0.551J/(g°C)
Explanation:
Specific heat is the amount of heat to required to raise the temperature of 1 gram substance to 1° C
The formula
C = q / m × ΔT ______ (1)
where ,
C = specific heat
q = heat
m = mass
ΔT = change in temperature
mass of the stainless steel is m = 1.55g
heat of the stainless steel is q = 141 J
the change in temperature is ΔT = 178°C
substitute all the value in the equation (1)
Answer:
a property ( colour,hardness and boiling point)
The nucleus is the part of the atom where energy is released after said atom is split.
Hope this helped :3
