Weathering is where something is changed or mutilated by the weather. Erosion is hwere water or an other substance digs awaya at something and wears it out. I don't exactly know the last one or how to explain
Answer:
the number of additional car lengths approximately it takes the sleepy driver to stop compared to the alert driver is 15
Explanation:
Given that;
speed of car V = 120 km/h = 33.3333 m/s
Reaction time of an alert driver = 0.8 sec
Reaction time of an alert driver = 3 sec
extra time taken by sleepy driver over an alert driver = 3 - 0.8 = 2.2 sec
now, extra distance that car will travel in case of sleepy driver will be'
S_d = V × 2.2 sec
S_d = 33.3333 m/s × 2.2 sec
S_d = 73.3333 m
hence, number of car of additional car length n will be;
n = S_n / car length
n = 73.3333 m / 5m
n = 14.666 ≈ 15
Therefore, the number of additional car lengths approximately it takes the sleepy driver to stop compared to the alert driver is 15
There are a lot of volume units, most specifically in English units, that are greater than one liter. The following are as follows:
gallon, which is equal to 4.54 liters
minim
barrel
cord
peck
bushel and;
hogshead
Also included are metric units which are dekaliter onwards.
Mass is the amount of matter in an object whereas weight is the force of gravity acting on the mass of an object. Different planets exert a different force of gravity on an object-meaning that an object's weight will change depending on the force of gravity acting on it, but it's mad will remain unchanged.
Not knowing how to convert the type of measurement according to your way of learning from where ever you come from.
