A control volume is a special type of closed system that does not interact in any way with its surroundings. FALSE

Answers

Answer 1

The given statement is false

What is closed system?

A system can be either closed or open: A closed system is a system that is completely isolated from its environment.

A closed system is that in which only the exchange of energy is allowed but the exchange of matter is not allowed. Example-When we boil water with a closed lid, the heat can exchange but matter cannot.

There are two types of systems: open and closed. An open system is one in which energy can be transferred between the system and its surroundings. The stovetop system is open because heat can be lost into the air. A closed system is one that cannot transfer energy to its surroundings.

An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.

Two points in a rectangular coordinate system have the coordinates (5.0, 2.7) and (−3.1, 5.5), where the units are centimeters. Determine the distance between these points.

Answers

Answer:

V2 = 5.0 i + 2.7 j

V1 = -3.1 i + 5.5 j vector description of points in question

Or (X2 - X1) = 5.0 - (-3.1) = 8.1 distance between x-coordinates

(Y2 - Y1) = 2.7 - 5.5 = -2.8 distance between y-coordinates

S = [(X2 - X1)^2 + (Y2 - Y1)^2]^1/2

S =[(8.1^2 + (-2.8)^2)]^1/2 = (8.1^2 + 2.8^2)^1/2

S = 73.45^1/2 = 8.57

a ball is tied to a string and swung so that the ball follows a circular path that lies in a horizontal the following statements is true in an inertial reference frame, i.e. a reference frame that is at rest with respect to the earth?

Answers

A: "The ball has changing velocity & changing acceleration" is true in regard to inertial reference frame.

The ball has changing acceleration and changing velocity in an inertial reference frame. As it moves in a circular path, it experiences a centripetal acceleration directed towards the center of the circle, which changes its velocity direction. This means the velocity of the ball is not constant in an inertial reference frame and is constantly changing, which is why the acceleration is also changing.
