A good visual lead is 20-30 seconds from the front of the vehicle, focusing in the center of the path of travel. Searching 20 to 30 seconds ahead, gives you time to assess within the next ..12-15 seconds, actions you may need to take to control an approaching risk.
Discussion:
Keeping eye focus centered in a path of travel at an interval of 20 to 30 seconds away from the vehicle is critical to gaining enough info. as possible in the driving scene. Good targeting sets up good sight lines for referencing and good peripheral fields for observing changes.
- It is important to look ahead 12-15 seconds into your target area as one drives. Compromise. space by giving as much space to the greater of two hazards.

Answer:
The claim is false. (
).
Explanation:
The real coefficient of performance of the food freezer is:
The ideal coefficient of performance, that is, when freezer has a reversible process, is:
A real freezer has a coefficient of performance lesser than or equal to ideal coefficient of performance. Since supposed real coefficient of performance is greater than ideal coefficient of performance. The claim is proved to be false.
Answer:
Gas constant = 0.499 kJ/kg.K
Explanation:
n = number of moles
nN2 = 2 kmol
nCO2 = 4 kmol
Total number of moles = 2 + 4 = 6 kmol of mixture
let y be the mole fractions of the mixture:
yN2 = number of moles of N2/total number of moles = 2/6 = 0.33 kmol/kmol
yCO2 = number of moles of CO2/total number of moles = 4/6 = 0.67 kmol/kmol
The molar mass of an ideal gas mixture is defined by the mass of mixture divided by the total number of moles of the mixure:
We assume there is 100 kg of the gas mixture if the mass is not given.
Therefore:
Molar mass of mixture = mass of mixture/total moles of mixture = 100kg/6kmol = 16.67kg/kmol
The gas constant of a mixture is defined as the universal gas constant (ideal gas constant = 8.314 kJ/kmol.K) divided by the molar mass of the mixture.
Therefore:
The gas constant of the mixture = 8.314kJ/kmol.K/16.67kg/kmol = 0.499 kJ/kmol.K
