Light will make the object appear “broken” or in an irregular shape.
Refraction is the change in direction of waves.
1/2mv^2
1/2x12x10^2=600J
The kinetic energy is 600J
Answer:
354.72 m/s
Explanation:
= mass of lead bullet
= specific heat of lead = 128 J/(kg °C)
= Latent heat of fusion of lead = 24500 J/kg
= initial temperature = 27.4 °C
= final temperature = melting point of lead = 327.5 °C
= Speed of lead bullet
Using conservation of energy
Kinetic energy of bullet = Heat required for change of temperature + Heat of melting
