Satellite technology has allowed us to monitor areas that were once so remote that we had no way of monitoring them. Review the

statements and choose the one that best describes how we can use this technology to benefit the environment.
Large ocean liners use satellites to aid in navigation. This type of navigation aid is also used on cruise ships. Using satellites can help these large ships navigate waters during bad storms.

Satellite surveillance can be used to aid in port security. Satellite data can be monitored and evaluated by complex computer systems. These systems can alert officials when something unusual occurs.

Satellite technology allows us to monitor and track the changes in the polar ice sheets. This can help us plan and direct conservation efforts for the animals that depend on polar ice in order to survive.

Satellite surveillance has allowed us to map areas that were previously too remote to observe. This helps developers to locate and choose sites for large resorts.

Answer: Satellite technology allows us to monitor and track the changes in the polar ice sheets. This can help us plan and direct conservation efforts for the animals that depend on polar ice in order to survive.

Explanation:

A satellite orbits around Earth. We have different satellites for different purposes. A satellite has transmitter and receiver for sending and receiving information.  For the use of environment, only one statement seems correct that is: Satellite technology allows us to monitor and track the changes in the polar ice sheets. This can help us plan and direct conservation efforts for the animals that depend on polar ice in order to survive.

Rest options are true but not from the environment point of view.

We know that animals are dependent on the environment for their survival. polar ice caps are difficult to reach and monitor. For making conservation plan for the animals residing in these remote areas, satellite technology is very crucial.

What three factors decide how much gravitational potential energy a body has?
nikdorinn [45]

Answer:

1. Mass

2. Height

3. Gravitational Force Field

Explanation:

The three factors that decide how much gravitational potential energy a body has are: 1) The mass of the body itself, 2) The relative height at which the body is, because gravitational force varies with height i.e distance away from earth surface. 3) and finally the strength of the gravitational field the body is in.

A student standing in a canyon yells "echo", and her voice produces a sound wave of frequency of f = 0.61 kHz. The echo takes t
klasskru [66]

Answer:

d=627.9\ m  is the distance from the obstacle of reflection.

wavelength \lamb=0.5279\ m

Explanation:

Given that:

  • frequency of sound, f=610\ Hz
  • time taken for the echo to be heard, t=3.9\ s
  • speed of sound, v=322\ m.s^{-1}

We know,

\rm distance = speed \times time

<em>During an echo the sound travels the same distance back and forth.</em>

2d=v.t

2d=322\times 3.9

d=627.9\ m  is the distance from the obstacle of reflection.

<u>Now the wavelength of sound waves:</u>

\lambda=\frac{v}{f}

\lambda=\frac{322}{610}

\lamb=0.5279\ m

You testify as an expert witness in a case involving an accident in which car A slid into the rear of car B, which was stopped a
AfilCa [17]

Answer:

Explanation:

a Downward acceleration of car A along the slope

= g sinθ - μ g cosθ

= g ( sinθ - μ  cosθ)

= 9.8 ( sin 12 - .6 x cos 12 )

= 9.8 x ( .2079 - .5869 )

= - 3.714 m / s²

So there will be deceleration

v² = u² - 2 a s

= 18² - 2 x 3.714 x 24

= 324 - 178

= 146

v = 12 .08 m /s

b )

In the second case , kinetic friction changes

downward acceleration

= g ( sinθ - μ  cosθ)

= 9.8 ( sin12 - .1 x cos 12 )

9.8 ( .2079  -  .0978 )

= 1.079 m /s

there will be reduced acceleration

v² = u² - 2 a s

= 18² +2 x1.079 x 24

= 324 + 52

= 376

v = 19.4  m /s

8. Object A has a momentum of 80 Ns and collides and sticks to object B which has a momentum of -30 Ns. What is the momentum of
BigorU [14]

Given,

The momentum of the object A before the collision, p₁ =80 Ns

The momentum of the object B before the collision, p₂=-30 Ns

Given that the objects stick together after the collision.

From the law of conservation of momentum, the total momentum of a system should always remain the same. Thus the total momentum of the objects before the collision must be equal to the total momentum of the objects after the collision.

Thus,

p_1+p_2=p

Where p is the total momentum of the system at any instant of time.

On substituting the known values,

\begin{gathered} p=80-30 \\ =50\text{ Ns} \end{gathered}

Therefore the total momentum of the system is 50 Ns

Thus the momentum of the object AB after the collision is 50 Ns
