what is the total net force of 10n, 9n and 16n?

A truck is traveling at speed of 15 m/s on a slippery road. It will travel a distance of 57.4 meters before finally stop.

Using the Newton's 2nd law of motion:

Fs = m . a

Where:

Fs = friction force

m = mass of the truck

a = acceleration

Fs = μ . N

    = μ . mg

Where:

μ = coefficient of kinetic friction the tires and the road = 0.2

N = normal force = m . g

Hence,

μ . mg = m . a

a = μ . g

  = 0.2 x 9.8 = 1.96 m/s²

Using the equation of motion for a decelerated motion:

v² = u² - 2as

Where:

v = final speed = 0 (since the truck finally stop)

u = initial speed

s = distance

Hence,

0 = 15² - 2 x 1.96 x s

s = 225 / 3.92 = 57.4

Hence, the truck will travel a distance of 57.4 meters before finally stop.

If two separate containers A and B have the same volume and temperature, but container A has more gaseous molecules than B, then the container A will have higher pressure than container B.

According to the approximations of ideal gas conditions, the pressure of a gas is directly proportional to the number of molecules of a gas at constant temperature and volume.

Having this in mind, at constant temperature and volume, container A has more gaseous molecules than B, then container A will have higher pressure than container B.

Below is the calculation for proof that shows which container has the higher pressure while keeping the volume and temperature the same.

So, V a = V b

n a* T a/ P a = n b* T b/ P b

Here, T a = T b

P a = n a/n b * P b

n a/n b > 1

P a/ P b > 1

P a > P b

Thus, the container A will have higher pressure than container B.

Atoms' surrounding electron clouds can serve as diffraction gratings and x-ray scattering sites. This makes it possible to determine the structure of molecules as well as the solid-state structure (i.e., the lattice types and unit cell dimensions).

The principles of diffraction are based on Bragg's Law:

nλ=2dsinθ

n is the diffraction order, which is typically 1.

lambda is the radiation's wavelength of incidence

d is the distance between the lattice planes, where

is the angle between the incident radiation and the scattering plane.

Powder x-ray diffraction (PXRD), which gives the cell constants for the solid's unit cell, is used when the material is a powder.

The intensity of the diffraction peaks is utilised to determine all atom locations when the sample is a single crystal, which provides bond lengths and bond angles.

Newton (N) is the Unit of force. And 1 N is the force needed to accelerate 1 kilogram of mass at the rate of 1 meter/second..

In earth; 1 kg mass produce 9.81 N force in direction to the center of gravity of earth. In an other words, if mass produce 9.81 N force in  earth's surface that mass is must be 1 kg.

In your question; 600 N force is always 600N force.

When you measure the force of mass is 600 N on earth's surface, same mass is produce 600x(1.62/9.81) = 99.08 N on Moon, and 600x(3.71/9,81)= 226.91 N on Mars.

Resolving scaling factor you find the image vertices for dilation with center 0 0

Magnification is defined as a number or conversion factor used to change the size of a shape without changing its shape. Used to increase or decrease the size of an object. If you know the dimensions of the original shape and the dimensions of the enlarged (scaled up or down) shape, you can calculate the scale factor.

For example, a rectangle is 5 units long and 2 units wide. If you scale this rectangle by a factor of two, the sides are 10 and 4 units, respectively. So you can use the scale factor to get the dimensions of the modified figure.

The coordinates of the image vertices can be calculated as follows:

For vertex A (-3, 1) then A' (4 × -3, 4 × 1) = A' (-12, 4)

For vertex B then (4, -3) then B' (4 × 4, 4 × -3) = B' (16, -12)

The parallel axis theorem connects a shape's moment of inertia about a parallel centroidal axis to its moment of inertia about any other axis.

This theorem is particularly helpful since it allows us to compute a shape's moment of inertia around any parallel axis by adding the appropriate correction factor to our knowledge of the shape's centroidal moment of inertia. Alternatively, by deducting the same factor from the moment of inertia about an axis, we can determine the related centroidal moment of inertia.

The influence of salinity, temperature and physiological development on habitat choice by juvenile salmon is poorly understood.

Answer:

Below

Explanation:

It is likely that changes in salinity can affect the population of juvenile salmon in a number of ways. For example, if the salinity of the water increases, it can lead to increased stress on the fish and make it more difficult for them to survive.

This can lead to a decrease in the population of juvenile salmon. On the other hand, if the salinity decreases, it can make it easier for the fish to survive and potentially lead to an increase in the population.

It is important to note, however, that the exact response of the population to changes in salinity will depend on a variety of factors, such as the species of salmon, the specific environment in which they are living, and the magnitude of the change in salinity.
