The correct Answer is:
To devise a circuit that opens a common gate when a car enters either of the two garages (Garage A or Garage B) or both, we can utilize diodes to create an OR gate configuration. Here’s a step-by-step solution: ### Step 1: Understand the Requirements We need a circuit that allows the gate to open if: - A car enters Garage A (input A) - A car enters Garage B (input B) - Both garages have cars entering ### Step 2: Create a Truth Table We can summarize the conditions in a truth table: | Input A (Garage A) | Input B (Garage B) | Gate Output | |---------------------|---------------------|-------------| | 0 | 0 | 0 | | 1 | 0 | 1 | | 0 | 1 | 1 | | 1 | 1 | 1 | This truth table indicates that the gate should open (output = 1) if either input A or input B is 1. ### Step 3: Recognize the Logic Gate The truth table resembles the behavior of an OR gate. Therefore, we can use diodes to create this OR logic. ### Step 4: Draw the Circuit 1. **Components Needed**: - 2 Diodes - 1 Resistor - A gate mechanism (represented as a load) 2. **Circuit Configuration**: - Connect the anode of the first diode to the input from Garage A. - Connect the anode of the second diode to the input from Garage B. - Connect the cathodes of both diodes together to one end of the resistor. - Connect the other end of the resistor to the gate mechanism (load). - Connect the ground to the other side of the gate mechanism. ### Step 5: Explain the Working - When a car enters Garage A, the input A becomes high (1), allowing current to flow through the first diode, turning on the gate. - When a car enters Garage B, the input B becomes high (1), allowing current to flow through the second diode, also turning on the gate. - If both garages have cars entering, both diodes conduct, ensuring the gate opens. ### Final Circuit Diagram ``` Garage A ----|>|----+ Diode 1| +---[R]--- Gate Diode 2| Garage B ----|>|----+ ```

The colloidal particles are electrically charged as a indicated by their migration towards cathode or anode under the applied electric field. In a particular colloidal system, all particles carry either positive charge or negative charge. The electric charge on colloidal particles orginate in several ways. According to preferential adsorption theory, the freshly obtained precipitate particles adsorb ions from the dispersion medium, which are common to their lattice and acquire the charge of adsorbed ions. For example, For example, freshly obtained Fe(OH)_(3) precipitated is dispersed, by a little FeCl_(3) , into colloidal solution owing to the adsorption of Fe^(3+) ions in preference. Thus sol particles will be positively charged. In some cases the colloidal particles are aggregates of cations or anions having ampiphilic character. When the ions posses hydrophobic part (hydrocarbon end) as well as hydrophilic part (polar end group), they undergo association in aqueous solution to form particles having colloidal size. The formation of such particles, called micelles plays a very important role in the solubilization of water insoluble substances, (hydrocarbon, oils, fats, grease etc.). In micelles, the polar end groups are directed towards water and the hydrocarbon ends into the centre. The charge on sol particles of proteins depends on the pH. At low pH, the basic group of protein molecule is ionized (protonated) and at higher pH (alkaline medium), the acidic group is ionized. At isoelectric pH, characteristic to the protein, both basix and acidic groups are equally ionized. The stability of colloidal solution is attributed largely to the electric charge of the dispersed particles. This charge causes them to be coagulated or precipitated. On addition of small amount of electrolytes, the ions carrying oppiste charge are adsorbed by sol particles resulting in the neutralization of their charge. When the sol particles either with no charge or reduced charge, come closer due to Brownian movement, they coalesce to form bigger particles resulting in their separation from the dispersion medium. This is what is called coagulating or precipitation of the colloidal solution. The coagulating power of the effective ion, which depend on its charge, is expressed in terms of its coagulating value, defined as its minimum concentration (m mol/L) needed to precipitate a given sol. Which of the following ions would have the minimum coagulating value for sol obtained on peptizing Sn(OH)_(4) by little NaOH solution?

Now when the surface is smooth , the toy car travels larger distance. It is found that friction is caused by interlocking of irregularities on the two surfaces in contact . Irregularities between two surfaces in contact. The above figure shows minute irregularities on two surfaces which are locked into one another . If we want to move any surface , some part of the external force applied is used to overcome this interlocking want to maove any surface , some part of the external force applied is used to overcome this interlocking . A rough surface has a large number of irregularities , so the force of friction is greater . A smooth surface has small number of irregularities , so the force of friction is less. 2. Normal reaction : The force of friction depends on the normal reaction also. As the normal reaction increases , the interlocking between two surfaces in contact increases as they press harder against each other and hence friction increases .

An unmanned satellite A and a spacecraft B are orbiting around the earth in the same circular orbit as shown. The spacecraft is ahead of the satellite by some time. Let us consider that some technical problem has arisen in the satellite and the astronaut from B has made it correct. For this to be done docking of two ( A and B ) is required (in layman terms connecting A and B ). To achieve this, the rockets of A have been fired in forward direction and docking takes place as shown in the figure below: Take mass of the earth =5.98xx10^(24)kg Radius of the earth =6400 km Orbital radius =9600km Mass of satellite A=320 kg Mass of spacecraft =3200 kg Assume that initially spacecraft B leads satellite A by 100s , i.e., A arrives at any particle position after 100 s of B’s arrival. Based on the above information answer the following questions. To dock A and B in the above-described situation, one can use the rocket system of either one, i.e., either of A or of B . To accomplish docking in the minimum possible time which is the best way?
