Stopping distance of vehicles : When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initial velocity ( v 0 ) and the braking capacity, or deceleration, ?a that is caused by the braking. A car travelling at speed 72km/hr suddenly applies the brake with the deceleration of 5m/s2. Find the stopping distance of the car -Science

Vehicle tyres are inflated properly – (1) to ensure smooth running. (2) to allow the vehicle to take more load. (3) to avoid skidding and to minimize friction (4) to go fast and save fuel.

Description : Vehicle tyres are inflated properly – (1) to ensure smooth running. (2) to allow the vehicle to take more load. (3) to avoid skidding and to minimize friction (4) to go fast and save fuel.

Last Answer : (3) to avoid skidding and to minimize friction Explanation: Under-inflated tyres create more friction with the road, increasing fuel consumption by up to ten per cent and are prone to skidding on ... or slippery surfaces. Low pressures also lead to premature wear and risk of tyre blowout or bulging.

Vehicle tyres are inflated properly (1) to ensure smooth running. (2) to allow the vehicle to take more load. (3) to avoid skidding and to minimise friction (4) to go fast and save fuel.

A 15-year-old girl was seen by her family physician because of increasing lethargy. She had a recent history of the "flu". Biochemistry tests show that she has renal impairement. serum sodium 140 mmol/L (137 - 144) serum potassium 4.2 mmol/L (3.5 - 4.9) serum urea 28 mol/L (2.5 - 7.5) serum creatinine 280 µmol/L (60 - 110) Her condition does not improve after several weeks on corticosteroid therapy, so a renal biopsy is performed. The biopsy demonstrates the presence of segmental sclerosis of 3 of 10 glomeruli identified in the biopsy specimen. Immunofluorescence studies and electron microscopy do not reveal evidence for immune deposits. What is the most appropriate advice to give regarding her condition? 1) She has an underlying malignancy 2) She may require a renal transplant in 10 years

Biochemistry tests show that she has renal impairement. ... will likely develop a restrictive lung disease 5) She will probably improve with additional corticosteroid therapy

Last Answer : Answers-2 The findings point to focal segmental glomerulosclerosis (FSGS), which leads to chronic renal failure in half of cases. The lack of resolution with corticosteroid therapy and the progression to chronic renal failure is what sets FSGS apart from minimal change disease.
