Two trains are traveling in the same direction.The first one leaves at 8 AM with a speed of 40km/hr and the second leaves at 11 AM with a speed of 60 km/hr. At what time will the second train catch the first train?
As per the question we can arrange the given data for the two trains as, Train 1 Spee…
A boat travels 30 km upstream in the same amount of time it takes to travel 60 km downstream in the same river. If the speed of the river is 4 km/h, what is the speed of the boat in still water?
From the given situation in the question above, let us assume that speed of the boat …
Two cars start at the same time from one point and move along two roads at right angles. Their speeds are 36 km/hr and 48 km/ hr respectively. After 15 seconds, what will be the distance between them?
There are two speeds given in the question, V₁ = 36km/hr V₂ = 48km/hr converting the…
A series LCR circuit with R = 20 Ω, L = 1.5 H and C = 35 µF is connected to a variable-frequency 200 V ac supply. When the frequency of the supply equals the natural frequency of the circuit, what is the average power transferred to the circuit in one complete cycle?
The given data can be listed as, R = 20 Ω L = 1.5 H C = 35 µF RMS V = 200 Volt To find…
