Here are the solutions to all the questions in English: SECTION A 1. To calculate the volume of each drop, we first need to find the total volume of liquid dispensed. Step 1: Calculate the total volume of liquid dispensed. The initial burette reading was 22 cm^3 and the new reading is 56 cm^3. Total volume = New reading - Initial reading Total volume = 56 cm^3 - 22 cm^3 Total volume = 34 cm^3 Step 2: Calculate the volume of each drop. There are 50 drops dispensed. Volume per drop = Total volumeNumber of drops Volume per drop = 34 cm^350 Volume per drop = 0.68 cm^3 2. To calculate the tension, T_A, in string A, we will use the Principle of Moments. Given data: • Weight of the plank (W_p) = 50 N • Length of the plank (L) = 5 m • Weight of the block (W_b) = 100 N • String A is 2.0 m from the left end. • String B is 1.5 m from the right end, which is 5.0 m - 1.5 m = 3.5 m from the left end. • The center of the plank (where W_p acts) is 5.0 m / 2 = 2.5 m from the left end. • The block is placed at the center of the plank, so W_b also acts at 2.5 m from the left end. Step 1: Choose the pivot point. We will choose point B as the pivot to eliminate T_B from the moment calculation. Distance of T_A from B = 3.5 m - 2.0 m = 1.5 m. Distance of W_p from B = 3.5 m - 2.5 m = 1.0 m. Distance of W_b from B = 3.5 m - 2.5 m = 1.0 m. Step 2: Apply the Principle of Moments: Sum of clockwise moments equals sum of anticlockwise moments. Clockwise moments (from W_p and W_b) = (W_p × distance from B) + (W_b × distance from B) Anticlockwise moments (from T_A) = T_A × distance from B Step 3: Equate the moments and solve for T_A. T_A × 1.5 m = (50 N × 1.0 m) + (100 N × 1.0 m) T_A × 1.5 m = 50 Nm + 100 Nm T_A × 1.5 m = 150 Nm T_A = 150 Nm1.5 m T_A = 100 N 3. If a constant force is applied to an object moving at a constant velocity, the object will accelerate according to Newton's Second Law (F=ma). This means its velocity will change. Velocity includes both magnitude (speed) and direction. Here are two possible changes in the state of motion of the object: • Speed: The speed of the object will change. It can increase or decrease depending on the direction of the applied force relative to the initial direction of motion. • Direction: The direction of the object's motion will change. This will particularly happen if the applied force is not parallel to the initial direction of motion. 4. To calculate the density of the soil, we need the mass of the soil and the volume of the soil. Given data: • Mass of empty density bottle (m_b) = 23.5 g • Mass of bottle + soil (half-filled) (m_b+s) = 62.1 g • Mass of bottle + soil + water (completely filled) (m_b+s+w_1) = 98.1 g • Mass of bottle + water (completely filled) (m_b+w_2) = 73.5 g Step 1: Calculate the mass of the soil (m_s). m_s = m_b+s - m_b m_s = 62.1 g - 23.5 g = 38.6 g Step 2: Calculate the mass of water that fills the empty bottle (m_w\_full). m_w\_full = m_b+w_2 - m_b m_w\_full = 73.5 g - 23.5 g = 50.0 g Step 3: Calculate the volume of the bottle (V_bottle). We assume the density of water (_water) is 1 g/cm^3. V_bottle = m_w\_full_water V_bottle = 50.0 g1 g/cm^3 = 50.0 cm^3 Step 4: Calculate the mass of water added to the soil to fill the bottle (m_w\_added). m_w\_added = m_b+s+w_1 - m_b+s m_w\_added = 98.1 g - 62.1 g = 36.0 g Step 5: Calculate the volume of water added (V_w\_added). V_w\_added = m_w\_added_water V_w\_added = 36.0 g1 g/cm^3 = 36.0 cm^3 Step 6: Calculate the volume of the soil (V_s). The volume of the soil is the volume of the bottle minus the volume of the water added. V_s = V_bottle - V_w\_added V_s = 50.0 cm^3 - 36.0 cm^3 = 14.0 cm^3 Step 7: Calculate the density of the soil (_s). _s = (m_s)/(V_s) _s = 38.6 g14.0 cm^3 _s ≈ 2.757 g/cm^3 Rounding to three significant figures: _s = 2.76 g/cm^3 5. The stability of a body refers to its ability to return to its original position after being slightly displaced. Two factors that affect the stability of a body are: • Base Area: A larger base area increases stability because it provides a wider support region, making it harder for the center of gravity to move outside the base when tilted. • Height of the Centre of Gravity: A lower center of gravity increases stability. When the center of gravity is low, a larger tilt is required for the line of action of the weight to fall outside the base, thus making the object more stable. 6. To calculate the work done by the force, we use the formula for work done when the force is applied at an angle to the direction of motion. Given: • Force (F) = 10 N • Angle () = 60^ to the horizontal • Distance (d) = 5 m Step 1: Write down the formula for work done. W = Fd Step 2: Substitute the given values into the formula. W = (10 N)(5 m) (60^) Step 3: Calculate the value of (60^) and perform the multiplication. We know that (60^) = 0.5. W = (10 N)(5 m)(0.5) W = 50 Nm × 0.5 W = 25 J Last free one today — make it count tomorrow, or type /upgrade for unlimited.
