What is not an essential part of isolated soldier guidance
mel-nik [20]

Answer:

Option B, visual sightings

Explanation:

Options for the question are

A) accountability mechanism

B) visual sightings

C)  intelligence

D) surveillance

E) reconnaissance  operations, or communications

Solutions

The Fundamentals of Army Personnel Recovery (PR) outlines certain circumstances under which a person has to undergo survival situation thereby taking the necessary steps to avoid capture and return safely to their respective unit.

An isolated soldier is expected to know where they are, upcoming route and rally points. They are supposed to know the near and far recognition signals, recovery site protocols, challenge and password etc. A proper preparation is to be done for this including planning, medicines, kits, etc.  

Visual sightings is not an essential part of isolated PR

Hence, option B is correct

How much work (in j) must be done to lift a stack of bricks, which has a mass of 400 kg, from the ground to a height of 3 m? (g
svetoff [14.1K]
Given: Mass m = 400 Kg;   Height h = 3 m;     g = 10 m/s²

Required:  Work = ?

Formula: Work = Force x distance  F = ma    a = g    F = mg

W = fd

W = mgh

W = (400 Kg)(10 m/s²)( 3 m)

W = 12,000 Kg.m²/s²

W = 12,000 J

You connect five identical resistors in series to a battery whose EMF is 12.0 V and whose internal resistance is negligible. You
avanturin [10]

Answer:

The resistance of each resistor is 2.5 Ω

The potential difference across each resistor is 2.4 V.

Explanation:

By Ohm's law,

<em>V </em>=<em> IR</em>

where <em>V</em> is the potential difference or voltage across an element, <em>I</em> is the current flowing through it and <em>R</em> is its effective resistance.

For the group of five resistors, let their combined resistance be <em>R</em>.

Then

(12.0 V) = (0.961 A)(<em>R</em>)

R = \dfrac{12}{0.961}\,\Omega

Because they are in series, <em>R</em> is the arithmetic sum of their individual resistances. Because they are all identical, the resistance of each resistor is

= \dfrac{12}{5\times0.961}\,\Omega = 2.5\,\Omega

Also, because they are in series and are equal, the EMF is distributed across them equally. Therefore, the potential difference across each resistor is

\dfrac{12.0\text{ V}}{5} = 2.40\text{ V}
