Answer:
See explanation for details
Explanation:
The full mechanism of the nitration of an aromatic ring (benzene) is shown in the image attached. The electrophile is NO2^+. It us generated from HNO3/H2SO4. it attacks the benzene ring and leads to the formation of a delocalized intermediate which rearranges to form the product, in this case, nitrobenzene. Note that the intermediate can also be represented by a number of resonance structures.
Gravitational Potential Energy (GPE) = 9.8m/s² (rate of gravity) x 8,000,000kg of water x 50.0m
GPE = 3,294,000,000 Joules (J) which is also the change in GPE

Let x be the speed of the slower car and that x + 20 be the speed of the faster car. The time it takes for the object to travel a certain distance is the quotient when distance is divided by the speed.
t = d / S
Substituting the given and equating their times,
t = 225 / (x + 20) = 165 / x
The value of x is equal to 55. Therefore, the value of t is equal to 3 hours.
The velocity of the object at the end of 3.00 seconds is 29.4 m/s.
Find the initial velocity of an object by dividing the time it took the object to travel the specified distance by the total distance. An object at rest has zero velocity and remains so. Such an object does not change its state of motion unless an unbalanced force acts on it. The velocity of a body at rest must be zero, but the acceleration of a body at rest obviously cannot be zero.
Particles thrown vertically upwards will momentarily stop at the highest point of their movement. In free fall the object is affected only by gravitational acceleration. Acceleration is a non-zero value, so the velocity changes and increases as the object falls. This is because acceleration is defined as the rate of change of velocity with respect to time.
