<span>KE = (1/2)mv^2
KE = (1/2)(600 kg)(12 m/s)^2
KE = (1/2)(600 kg)(144 m^2/s^2)
KE = 43,200 kg*m^2/s^2 = 43,200 Joules
The kinetic energy of the car is 43,200 Joules.</span>
Answer:
Nitric oxide.
Explanation:
Superoxide may be defined as the compounds that contain the superoxide anions like oxygen anion (O2-). This is also known as the reactive oxygen species.
These anions are generated by the immune system to kill the pathogens. These superoxide include the species like NO, NO2. These super oxide anions are toxic to the cell membrane and also plays an important role in the process of ageing.
Thus, the correct answer is option (A).
Solar System Formation. Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.
Answer:
Air speed of bird is 
mph
Explanation:
let the speed of the bird in still air be "X"
Speed of the bird when it flies in the direction of flow of wind 
Speed of the bird when it flies in the opposite direction of flow of wind 
The total time taken is equal to 
minutes
hours
The distance in miles is equal to 
miles
On solving the above equation, we get -
Air speed of bird is mph
