Average speed is defined as ratio of total distance covered and total time
now we will have
now total distance moved is
total time is given as
now average speed is given as
so its average speed is 0.1 km per minute
answer is 3 >
3x this the correct answer
Answer:
(a) the maximum temperature and pressure that occur during the cycle are 1780.46K and 4911.58kPa respectively.
(b) the net work output is 451.78kJ/kg
(c) the thermal efficiency is 56.47%
(d) the mean effective pressure for the cycle is 86.011kPa
(e) power output from the cycle - there is no data to get this value since the speed (revolution per minute) of the engine is not given.
Explanation:
It is difficult to get type the calculation here but I have attached them in pages of 4.

Answer:
3 Hz
Explanation:
A beat is the pattern of interference among two waves with frequencies which are different.
The difference of the frequencies of the waves gives us the beat frequency.
Here, one frequency is , the other frequency is
So, the beat frequency
The beat frequency that is produced is 3 Hz
The correct answer is *mechanical advantage*
