Answer:
Absolute zero = 0 K or - 273°C
Explanation:
Absolute zero :
When the entropy and enthalpy of the ideal system reach at the minimum value then the temperature at that condition is known as absolute zero condition.
Absolute temperature is the minimum temperature in the temperature scale.The value of absolute zero is 0 K.
We know that

F=Temperature in Fahrenheit scale
K=Temperature in Kelvin scale
C=Temperature in degree Celsius scale
When K = 0


C= - 273°C
Absolute zero = 0 K or - 273°C
Explanation:
4 Fe + 3 O₂ → 2 Fe₂O₃
On the left side, there are 4 Fe atoms and 6 O atoms.
On the right side, there are 4 Fe atoms and 6 O atoms.
The reaction is balanced.

i really didn't understand the question
im soo so sorry
Answer:
The magnitude of the velocity of the third fragment is 212.13 m/s.
Explanation:
Given that,
Speed = 100 m/s
Vertical speed of first fragment = 150 m/s
Vertical speed of second fragment = 150 m/s
We need to calculate the vertical speed of third fragment
Using conservation of momentum


Put the value into the formula



We need to calculate the horizontal speed of third fragment
Using conservation of momentum


Put the value into the formula



We need to calculate the magnitude of the velocity of the third fragment

Put the value into the formula


Hence, The magnitude of the velocity of the third fragment is 212.13 m/s.
The environmental impact of mining affects, nesting habitats for wildlife. Wildlife either moves on, or dies.
