Explanation:
1)a=16m
b=28m
c=10m
volume of one box: V=16*28*10=4480m³
volume of 100 boxes: 4480*100=448000m³
2) 1960
3) 7: meter-length, kilogramme-mass, second-time, ampere-electric current, kelvin-temperature, candela-luminous intensity, mole-amount of substance
4)Area: S=a*b
Volume: V=a*b*c
Answer:I think that is false
Explanation:
Answer:
It would take 1 s to hear the echo.
Explanation:
Here, the sound covered a total of 340 meters, since it bounces off the canyon wall and travels back to Miles in the form of echo.
The time elapsed can be determined by,
v =
⇒ t =
where: v is the speed of sound in air (343 m/s), D is the distance of the nearest canyon (170 m).
So that,
2D = 2 x 170 = 340 m
Thus,
t =
= 0.9913 s
t = 1 s
It takes 1s for Miles to hear his echo.
Answer: When force 3F is applied, the distance the puck travels in time t is 3x

Answer:
Control valves are used in many processes to control flow, pressure, temperature or other variables. The type of valve used will depend on the size of the pipe, the overall pressure that the system operates, the flowing media, process conditions, and other factors.
Also
A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.
