Sauron [17]






Hi Pupil Here is Your Answer ::




➡➡➡➡➡➡➡➡➡➡➡➡➡



Balanced Forces =》 If the resultant of several forces acting on a body is zero, the forces are said to be Balanced Forces.

Or

When two forces of equal magnitudes but acting in opposite direction on an object simultaneously then the object continuous in its state of rest all uniform motion in a straight line such forces acting on the object are known as Balanced Forces.



Unbalance Forces =》 If the resultant of several forces acting on a body is not zero, the forces are said to be Unbalanced Forces.

Or


When two forces of unequal magnitudes act in opposite direction on an object simultaneously then object moves in the direction of the force with larger magnitude forces. These force acting on the object are known as Unbalanced Forces.

PLS ANSWER FAST WILL GIVE BRAINLY!!!!!!!
Ivahew [28]

Answer:

the answer is the explaination

Explanation:

Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. Based on the research conducted, it is evident that new ways to prevent erosion must be obtained. Each way that is currently used has extensive negative effects on beaches and their natural tendencies.

Analyze why we say an object is accelerating when we usually mean that it is speeding up and an object slowing down also is acce
dem82 [27]

(And don't forget that an object going around a curve at a constant speed is also accelerating.)

I believe there are two reasons:

1). The term is inadequately taught in the American public school system ... along with much of the rest of Science and Math in general.

2). The word became permanently and indelibly corrupted when the automotive industry decided to name the gas pedal the "accelerator".

During which stage of the water cycle does water from the ocean form clouds?
Nataly [62]

Answer:

Condensation

Explanation:

Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds.

Two spherical shells have a common center. A -2.1 10-6 C charge is spread uniformly over the inner shell, which has a radius of
julsineya [31]

Answer:

a) E_total = 6,525 10⁴ N /C ,field direction is radial outgoing

b)  E_total = 1.89 10⁶ N / C, field is incoming radial

c) E_total = 0

Explanetion:

For this exercise we can use that the charge in a spherical shell can be considered concentrated at its center and that the electric field inside the shell is zero, since Gauss's law is

                Ф = E .dA = q_{int} /ε₀

inside the spherical shell there are no charges

The electric field is a vector quantity, so we calculate the field created by each shell and add it vectorly.

We have two sphere shells with radii 0.050m and 0.15m respectively

a) point where you want to know the electric field d = 0.20 m

shell 1

the point is on the outside,d>ro,  therefore we can consider the charge to be concentrated in the center

            E₁ = k q₁ / d²

             

shell 2

the point is on the outside,d>ro

             E₂ = k q₂ / d²

the total camp is

              E_total = -E₁ + E₂

              E_total = k ( \frac{-q_1 + q_2}{d^2})

              E_total = 9 10⁹ (-2.1 10⁻⁶+ 5 10⁻⁶ / .2²

              E_total = 6,525 10⁵ N /C

The field direction is radial and outgoing ti the shells

b) the calculation point is d = 0.10m

shell 1

point outside the shell d> ro

                 E₁ = k q₁ / d²

shell 2

the point is inside the shell d <ro

Therefore, according to Gauss's law, since there are no charges in the interior, the electrioc field is zero

                E₂ = 0

               

                 E_total = E₁

                 E_total = k q₁ / d²

                 E_total = 9 10⁹ 2.1 10⁻⁶ / 0.1²

                 E_total = 1.89 10⁶ N / A

As the charge is negative, this field is incoming radial, that is, it is directed towards the shell 1

c) the point of interest d = 0.025 m

shell 1

point  is inside the shell d< ro

                 

as there are no charges inside

                     E₁ = 0

shell 2

point is inside the radius of the shell d <ro

                    E₂ = 0

the total field is

                    E_total = 0
