Answer:

When two objects collide and stick together, what will happen to their speed, assuming momentum is conserved? They will move at the same velocity as whichever object was fastest initially. They will move at the same velocity of whichever object was slowest initially.

Explanation:

The correct answer is that when two objects collide and stick together, BOTH objects will change speed.
If they are moving in the same direction, the faster moving object will slow down and the slower moving object will speed up.
If they are moving in opposite directions the faster will slow down and the slower one will change direction.

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

At one moment during a walk around the block, there are four forces exerted upon Fido - a 10.0 kg dog. The forces are:
Ann [662]

Explanation:

Given that,

Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)

Fnorm = 64.5 N, up

Ffrict = 27.6 N, left

Fgrav = 98 N, down

(a) Resolution of the applied force:

Horizontal component,

F_x=F\cos\theta\\\\=67\times \cos(30)\\\\=58.02\ N

Vertical component,

F_y=F\sin\theta\\\\=67\times \sin(30)\\\\=33.5\ N

(b) Net horizontal force :

F_x=58.02+(-27.6),\ \text{frictional force act in opposite direction of motion}\\\\F_x=30.42\ N

It is positive, it will act in right side

Net vertical force :

F_y=33.5+64.5+(-98),\ \text{gravitational force acts in downward direction}\\\\F_y=0

Hence, it is clear that the net force is in horizontal direction i.e. 30.42 N due right side.

What is the wavelength of the sound you hear as a train
NeX [460]

As the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.

<h3>What is wavelength?</h3>

Wavelength is the distance traveled by a wave in a given period of time.

Relationship between wavelength, speed and frequency of sound

v = fλ

where;

  • v is the speed of the sound
  • f is the frequency of the sound
  • λ is the wavelength of the sound

As the frequency of the sound increases, the wavelength of the sound decreases.

Thus, as the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.
