Answer:
Pardon
Explanation:
Using the fundamental laws of mass-energy conservation. We can determine that the photon particle is fundamental and delivers the energy required to change the mass of an object into energy.
Answer:
there are 1,000m in a km, so 200km is 200,000m
200,000m/10m/s = 20,000s

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
