Answer:
To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.
From the definition of acceleration,
a = (velocity change)/(time required)
In this case you know that a = 5.0 m/s^2, so
time = (10.0 m/s)/(5.0 m/s^2)
= 2.0 seconds
Answer:
(D) all of the above
Explanation:
All of the choices describe matter.
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.

Answer:
As described, The mantle causes the tectonic plates to move.
Answer:
x = 0.327 m
Explanation:
Block 2 of mass 1.00 kg is at rest
spring constant = 200 N/m
Block 1 of mass 2 kg moving at 4 m/s
m₁ v₁ = (m₁ + m₂)V
2 x 4 = (2 + 1) V
V = 2.67 m/s
loss of kinetic energy = gain elastic potential energy
x = 0.327 m
hence, the spring compressed distance is equal to x = 0.327 m
