Question

solve the following question​

Answer 1

Answer:

Explanation: The time period of VCO is given as T=2×△t =(2×0.25×Vcc ×CT)/i =(0.5 V×cc×CT)/i = (Vcc×CT)/(2×i). 4. Determine the value of current flow in VCO, when the NE566 VCO external timing resistor RT =250Ω and the modulating input voltage Vc=3.25V. (Assume Vcc=+5v).

Answer 2

Answer:

✬ Distance = 1/4 km ✬

Step-by-step explanation:

Given:

Distance of Ali's house from school is 3/4 km.

Distance covered by him by bus is 1/2 km.

To Find:

Distance covered by him on foot ?

Solution: Let he walked x km. According to the question

➙ Total distance = Distance covered by (walk + Bus)

➙ 3/4 = x + 1/2

➙ 3/4 – 1/2 = x { 1/2 transported to LHS }

➙ 3 – 2/4 = x { LCM of 4 & 2 is 4 }

➙ 1/4 = x

Hence, Ali walked 1/4 km before taking bus.

★ Check ★

➮ Total distance = Distance covered by (walk + Bus)

➮ 3/4 = 1/4 + 1/2

➮ 3/4 = 1 + 2/4 { LCM of 4 & 2 is 4 }

➮ 3/4 km = 3/4 km

LHS = RHS
