False. Heat radiation from the sun cannot reach Earth, we cannot receive TV or GPS signals from satellites, and we cannot detect the light from distant stars.
Oh, wait . . .

Identify the type of circuit in which the user retains the physical path through the network, but only for the duration of a cal

Switched Circuit: This type of connection only maintains a dedicated physical circuit or path between two network nodes for the duration of the connection before data may be transmitted.

<h3>What do you mean by circuit?</h3>

A circuit in electronics is a complete circular channel via which electricity flows. A current source, conductors, and a load make up a straightforward circuit. The term circuit can be used in a broad sense to refer to any permanent path that energy, data or a signal can go through.

<h3>What are the 3 types of circuits?</h3>

Circuits can be divided into three categories: series, parallel, and series-parallel. The typical configuration of a single electrical circuit includes one or more resistance or load devices.

<h3>What function does a circuit represent?</h3>

The closed loop in which electricity can move is referred to as a circuit. Electricity can flow in a closed circuit without interruption from the power source through the conductor or wire to the load before returning to the ground or power source.

Three deer, A, B, and C, are grazing in a field. Deer B is located 62m from deer A at an angle of 51° north of West. Deer C is l

Anna71 [15]

Set deer A's position to be the origin. Let $c$ be the distance from deer A to deer C. We're given that deer B is 95 m away from deer C, which means the length of the vector $B-C$ is 95 (or $C-B$ ). Then

$|B-C|^2=(B-C)\cdot(B-C)=B\cdot B-2B\cdot C+C\cdot C=|B|^2-2B\cdot C+|C|^2$

$|B-C|^2=|B|^2-2|B||C|\cos(180-77-51)^\circ+c^2$

$95^2=62^2-2(62)(c)\cos52^\circ+c^2$

$c^2-124\cos52^\circ c-5181=0\implies c=120\,\mathrm m$
