The others either change but don’t decrease or they increase.
Answer:
The number of complete vibration or wave made in
one second is called frequency.
Answer:
60 km
Explanation:
For an object (or a person, such as in this case) moving at constant speed, the speed is equal to the ratio between the distance travelled and the time taken:
where
v is the speed
d is the distance
t is the time taken
In this case, we have:
v = 120 km/h is the speed
t = 30 min = 0.5 h is the time taken
Therefore, we can rearrange the equation to find the total distance travelled:
To develop the problem we will start by finding the energy taken by each cycle through the efficiency of the motor and the exhausted energy. Later the work will be found for the conservation of energy in which this is equivalent to the difference between the two calculated energy values. Finally the estimated time will be calculated with the work and the power given,








PART A)
Work done by the heat engine in each cycle = W



According to the value given we have that,


Power is defined as the variation of energy as a function of time therefore,




Therefore the interval for each cycle is 0.75s
