Among the choices above, the one that is most closely related to an activated complex is the transition state. The answer is letter D. This formation forms quickly and does not stay in a way compound is. It usually forms during the enzyme – substrate reaction.
50. kilometers during the next 0.50 hour, and
40. kilometers in the final 0.50 hour. What is the
car’s average speed for the entire trip?
(1) 45 km/h (3) 85 km/h
(2) 60. km/h (4) 170 km/h
The average speed of the car for the entire trip can be calculate by using:
where S is the total distance covered by the car, and t is the total time taken.
The total distance travelled by the car is:
while the total time taken is:
so, the average speed of the car is:
so, the correct answer is (3) 85 km/h.
The average speed of the car for entire trip is .
Further Explanation:
Speed is the measure of a quantity of an object the tells how fast the object is moving in the other words we can define the speed that it is the distance covered by an body divided by the time taken to cover that distance. It is a quantity with only magnitude so it is a scalar quantity.
The average speed is defined as the sum of all the distance traveled by the body divided by the sum of time taken to travel that distance.
Given:
The distance travel by the car is for .
The distance travel by the car is for .
The distance travel by the car is for .
.
Concept:
The expression for the average can be written as:
S = …… (1)
The distance travel by the car is for , distance travel by the car is for and distance travel by the car is for .
The sum of the distance is:
The sum of time taken to travel the distance is:
Substitute for total distance and for total time in equation (1).
Therefore, the average speed of the car for entire trip is .

Answer:
The percentage of its mechanical energy does the ball lose with each bounce is 23 %
Explanation:
Given data,
The tennis ball is released from the height, h = 4 m
After the third bounce it reaches height, h' = 183 cm
= 1.83 m
The total mechanical energy of the ball is equal to its maximum P.E
E = mgh
= 4 mg
At height h', the P.E becomes
E' = mgh'
= 1.83 mg
The percentage of change in energy the ball retains to its original energy,
ΔE % = 45 %
The ball retains only the 45% of its original energy after 3 bounces.
Therefore, the energy retains in each bounce is
∛ (0.45) = 0.77
The ball retains only the 77% of its original energy.
The energy lost to the floor is,
E = 100 - 77
= 23 %
Hence, the percentage of its mechanical energy does the ball lose with each bounce is 23 %
Answer: 23

Plasma...I believe is always a good conductor of electricity. I was tempted to say a solid, but not all solids are the same in composition and that goes for liquid and gas as well.
Hopefully this helped and good luck.
