Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:
In our case x = 0, then y will be:
Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:

What metal is not at room temperature?
Mercury is a metallic chemical element that is an only metal that is not a solid at room temperature.
Answer:The formula for kinetic energy is
(1/2) M V^2.
With M in kg and V in m/s, the answer will be in Joules.
K.E = 40joule
Explanation:
Answer:
1196.02 °C
Explanation:
If the kinetic energy is converted into heat,
then,
Kinetic energy of the copper = heat energy of the copper
1/2m(v²) = cm(t₂-t₁)
where m = mass of copper, v = velocity of copper, c = specific heat capacity of copper, t₂ = final temperature of copper, t₁ = initial temperature of copper.
Since the mass of copper remains the same,
1/2v² = c(t₂-t₁)
make t₂ the subject of the equation
t₂ = 1/2(v²/c)+t₁..................... Equation 1
Given: v = 950 m/s, c = 387 J/kg°C, t₁ 30 °C
Substitute into equation 1
t₂ = 1/2(950²/387)+30
t₂ = 1196.02 °C
Hence the temperature the bullet reach before it was stopped = 1196.02 °C
