Answer:
causes: unemployment, poverty,Lack of education,urbanization e.t.c
solutions:making people educated, giving people jobs
Reeeeeeeeeeeeeeeeeeeeeeeeeeee
Answer:
No
Explanation:
Heat engine is a device which operates between two thermal reservoir.One thermal reservoir supply the thermal energy to the heat engine and another thermal reservoir absorb heat rejected by heat engine.These thermal reservoir are infinite amount of heat capacity system.Temperature of thermal reservoir remain constant always.
So we can say that heat engine can not operate by using only one thermal reservoir.
Admission to the Engineering course at Cambridge is highly competitive, both in terms of the numbers and quality of applicants. In considering applicants, Colleges look for evidence both of academic ability and of motivation towards Engineering. There are no absolute standards required of A Level achievement, but it should be noted that the average entrant to the Department has three A* grades. You need to get top marks in Maths and Physics.All Colleges strongly prefer applicants for Engineering to be taking a third subject that is relevant to Engineering.
Hope that helps and good luck if you are applying. Can you please mark this as brainliest and press the thank you button and if you have any further questions please let me know!!
Generator Hz comes in because competing frequencies in a machine might cause instability and equipment damage. Thus, option B is correct.
<h3>
What is the role of hertz in the alternator?</h3>
This alternator will produce 30 cycles of voltage in a second if it has two poles. The frequency would thus be defined as 30 cycles per second, or 30 Hertz. The alternator's rotating speed and frequency are directly inversely related.
When compared to a two-pole alternator, a four-pole alternator produces two cycles of voltage in a second (or one hertz of frequency). The number of poles in an alternator has a direct relationship to its frequency.
RPM is a common unit of measurement for engine power (rpm). The ability of an engine to deliver power is indicated by frequency, which is a significant number.
Therefore, Tech B says that hertz is the amount of current flow produced by an alternator.
