Question-Cyclist starts from rest and acceleration at the rate of 2 metre per second square what will be his velocity after 5 seconds.─────────────────────Dont spam plzAnswer with explanationCaution - whose spam in my ques there 5 question i reported !! |
Answer» Answer:10 m/s Explanation:
Acceleration (a) = 2 m/s² Initial velocity (u) = 0 m/s Time (t) = 5 s
Final velocity (v) = ?
Analysis: There is a cyclist STARTS from rest accelerates with an acceleration of 2 m/s². Now we have to calculate final velocity of cyclist after 5 seconds. Let's find now ! If we remember, we have Newton's first law of motion i.e, [just put all the given values]
__________________________________
[put all the values again in the formula] ⟹ 10 = 0 + 2 × 5 ⟹ 10 = 0 + 20 ⟹ 10 = 10 LHS = RHS. Hence, verified ✔. Hope it HELPED you dear... |

. Find out the value of current throughresistance for the given circuit---1) 5A2)2A3) zero4) 4APlease answer this question. No spam plzz |
|
Answer» Answer: GIVEN:A circuit has been provided consisting of 2 resistance LOOPS connected by a resistance. To find:Current through the 2 ohm resistance. Concept:First of all , you should remember that current flows through a circuit only when the circuit is closed and forms a loop. If you look at the circuit, it is clear that the 2 ohm resistance I not present in a closed or looped circuit. So NO CURRENT flows through the 2 ohm resistance. Alternative way to think this :Assume that current flows through that 2 ohm resistance, then how will it come back because there is no other wire to RETURN back the current. So , FINAL answer : Current through 2 ohm resistor = 0 amp.Correct option : |

Meter rule is balanced by placing the knife edge at 50 cm mark and suspending a weight of 20 gf from 0 end.The centre of gravity of the ruler is2 pointsat the centre ie 50 cm marktowards the right of 50 cm marktowards the left of the 50 cm mark ie towards 20 gf weightnone of these |
|
Answer» Answer: Explanation: The center of gravity of a uniform half meter rule is 25 cm. The rule balances horizontally on a KNIFE edge at 29 cm mark when a weight of 20 kgf is SUSPENDED from one end. The difference in the center of gravity and the POINT of balance=29−25=4cm(Y) The weight is suspended at one of the extremes, Let US assume at the 50 cm end. Therefore, the distance from the point of knife edge to the weight =50−29=21cm(X) Weight of meter rule =YX× Suspended weight ∴ Weight of meter rule =421×20=105 kgf |
