Answer:
the rocket average speed is 12 kilometers per second
Explanation:
Given that
The distance is 1140 km
And, the time is 95 seconds
We need to determine the average speed in kilometers per second (km/s)
So as we know that
Speed = distance ÷ time
= 1,140 km ÷ 95 seconds
= 12 kilometers per second
hence, the rocket average speed is 12 kilometers per second
To cause the reaction, catalysts use the catalytic cycles, decomposition reactions, and combustion cycles.
<h3>What do you mean by a reaction?</h3>
A reaction refers to the chemical process where substances mutually act and are changed into different substances.
Catalytic cycles refer to the multistep reaction that involves the catalysts. It is considered the main method that describes the major role of catalysts.
Decomposition and combustion cycles are also used by the catalysts.
Therefore, A and B are the correct options.

Answer:
48%
Explanation:
The relative humidity can be determined using a dry bulb and a wet bulb. The wet bulb temperature is usually lower than the dry bulb temperature. Hence, to determine the relative humidity, the wet bulb temperature is subtracted from the dry bulb temperature to determine the difference. Then the relative humidity is now determined using this difference and the dry bulb temperature.
Difference between dry bulb temperature and wet bulb temperature = 12°C - 7°C = 5°C
We locate the difference of 5 at a with a dry bulb temperature of 12°C on the table to get:
Relative humidity = 48%
Answer:
2) broken windows
Explanation:
All of these are techniques of crime prevention through environmental design (CPTED) except for broken windows. This strategy states that the manipulation of the environment can help deter crime by making it more difficult for people to commit crimes, or by giving the impression that detection and apprehension are likely. Some of the measures used in this technique are planting trees and shrubs, using light effectively or encouraging pedestrian traffic.
