A motorist travels 406 km, West during a 7.0 hr period. What was the average velocity in (a) km/hr and (b) m/sec?

Average velocity = (displacement) / (travel time)

Without more details, I just have to assume that the 406 km
is the displacement ... that is, the straight-line distance between
the start point and the end point.  If there were any turns, loops,
or backtracks during the trip, then this question couldn't be answered,
because we don't know the displacement. 

a). Average velocity = (406 km) / (7.0 hours) = 58 km/hr West.

According to the requirements stated in the question, I still
have to convert this answer to a different unit in order to 
rightfully claim the full 5-points bounty.

b). (58 km/hour) x (1,000 m/km) x (1 hour / 3600 sec) =  16-1/9 m/sec .

Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Crazy boy [7]

Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.

If a 100 N net force acts on a 50 kg car, what will the acceleration of the car will be?
Allushta [10]
According to newton's law Force = mass * acceleration
so , 100 = 50 * a
so , a= 2 m/s^2

If the absolute temperature of a gas is 600 K, the temperature in degrees Celsius is
gavmur [86]
Kelvin is a base unit of temperature scale from SI that defines as zero degree Kelvin (absolute zero). The absolute zero is a hypothetical statement that all molecular movement stops because there is no transient of energy for the molecules to move. When converting temperature in degree Celsius to Kelvin, add 273. You are given 600K and you are asked to find it in degrees Celsius.  

T(K) = T(C) + 273
600 K = T(C) + 273
T(C) = 600 – 273
T(C) = 327 °C
