How come a 60 watt light bulb has a higer temperature that a 40 watt light bulb?
the formula for power is P=H/t where P stands for power, H for heat and t for time. here heat is directly proportional to power and time inversely propotional to power.there as power increases, heat increses ,whereas power decreses heat decreses.
Why the speed decreases when the poles increases in a motor?
because N=(120*f)/P where N= speed in rpm f= frequency in Hz P= no. of poles as the relations shows above it is cleare that speed of machine inversly proportional to no. of poles.. so as the poles increses, speed of the machine decreses
Is population a problem in our country?
yes,population is a problem in our country because it brings many problems.some of the problems are. 1.unemplyment increses 2.pollution increses 3.economic growth desreases 4.economic problems increses

Does automation increase the cost of production?
NO,basically automation helps to decreses the cost of production.by the help of automation ,large number of units are produced with very little amount of time with higher accuracy.if large number of units produced,slowly slowly cost decreses.But initially,may be the cost of unit was high because of huge infrastructure cost but day by day,it decreses as some costs are fixed cost .so more often cost of production directly affected by varriable cost.So finally,i want to conclude that,industrial automation helps to decrese the cost of production secondarily,but at primary stage,cost of production increses by automation due to huge initial investment.
How are sound frequency and wavelength related?
As freuency increses so does it's wavelength
