What comes before Action-reaction?

1 answer:

4 0

These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.

Finding spring constant given displacement of spring and distance traveled by a cart

Alborosie

- (spring constant) (new length of spring - original length of spring) = Force applied to spring.
that is
-kx=F

Did you only have how far the cart traveled? No mass or acceleration or speed or time taken?

A 0.32 kg turntable of radius 0.18 m spins about a vertical axis through its center. A constant rotational acceleration causes t

Kruka [31]

Answer: $18.85 rad/s^2$

Explanation:

Given

mass of turntable $m=0.32 kg$

radius $r=0.18 m$

$N=24 rev/s$

$\omega =2\pi N=2\pi 24$

$\omega =48\pi rad/s$

time interval $t=8 s$

using $\omega =\omeag _0+\alpha t$

where $\omega =final\ angular\ velocity$

$\omega _0=initial\ angular\ velocity$

$\alpha =angular\ acceleration$

$t=time$

$48\pi =0+\alpha \times 8$

$\alpha =6\pi rad/s^2$

$\alpha =18.85 rad/s^2$

Imagine that you work for a conservation organization. Your job is to make recommendations to restore an area of a prairie that

ella [17]

Answer:

The damaged prairie area can be restored through site preparation, replanting and putting species back on the landscape.

Explanation:

Prairie- this is a type of habitat with mostly grasses. It also consists of trees, occasional shrubs and flowering plants. This can be found around the world and is ecologically important for providing habitats for native animals and insects. It is perfectly adapted to the climate and requires minimal maintenance.

Once a prairie is damaged, it becomes an essential move to restore it immediately. This can be done through different human activities such as the following:

1. Site preparation- before doing anything else, it would be best to prepare the prairie site by removing debris from the fire. This will make everything easier once you start planting the crops or plants.

2. Replanting- this is probably the most essential move you can do. It would be best to plant high quality food plants that would provide nectar, pollen and seeds throughout the season. This will entice many birds and butterflies into the area. It will also make the native plants abundant which will, in turn, increase ecological diversity.

3. Putting species back on the landscape- when a wildfire occurs, it is a common sense that species also run away from their home (habitat). In order to create that natural habitat again, it would be best to put the species back to where they belong so they can restart their lives. This will resume the natural food webs and nutrient cycles.

The wavelength at which Earth’s emitted radiation is maximum is ______ at which the wavelength of the Sun’s emitted radiation pe

tatiyna

Answer:

inversely proportional to the temperature

Explanation:

Wein's displacement law states the wavelength at which Earth’s emitted radiation is maximum is inversely proportional to the temperature at which the wavelength of the Sun’s emitted radiation peaks.

λmax $= \frac{b}{T}$

where,

λmax is the maximum wavelength

b is a constant of proportionality called Wien's displacement constant (b = 2.897 × 10⁻³ m.K)

T is the absolute temperature in kelvins
