Answer:
The 80 mph car
Because the formula says 1/2 mass but for the velocity it is squared
<span>
Reaction rates are affected by reactant concentrations and temperature. this is accounted for by the c</span>ollision model.
-Hope this helps.
The answer is C. <span>Light travels at different speeds in water and in glass.</span>
Answer: 90 kgm/s
Explanation:
The momentum (linear momentum)
is given by the following equation:
Where:
is the mass of the skater
is the velocity
In this situation the skater has two values of momentum:
Initial momentum: 
Final momentum: 
Where:


So, if we want to calculate the difference in the magnitude of the skater's momentum, we have to write the following equation(assuming the mass of the skater remains constant):
Finally:
