MGVCL Exam Paper (30-07-2021 Shift 2) The wind speed increases with height because of reduction in the gravitational force reduction in lift effect of the air reduction of drag effect of the earth surface enhancement of drag effect on the earth surface reduction in the gravitational force reduction in lift effect of the air reduction of drag effect of the earth surface enhancement of drag effect on the earth surface ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Wind speed increases as the height from the ground increases mainly due to the decrease in the friction produced by land terrain.
MGVCL Exam Paper (30-07-2021 Shift 2) A MOSFET rated for 15 A, carries a periodic current as shown in figure. The ON state resistance of the MOSFET is 0.15 Ω. The average ON state loss in the MOSFET is 15 W 33.8 W 3.8 W 7.5 W 15 W 33.8 W 3.8 W 7.5 W ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Ip = 10 ATon = πT = 2πIavg = Ip*√(Ton/T)Iavg = 10*√(1/2)= 7.07 AThe average ON state loss in MOSFET, P = Iavg²*RP = 7.07²*0.15P = 7.5 W
