Answer:

Limited resources lead to competition between organisms

Explanation:

Competition is a negative interaction that occurs among organisms whenever two or more organisms require the same limited resource. All organisms require resources to grow, reproduce, and survive. However, organisms cannot acquire a resource when other organisms consume or defend that resource.

The direction of the electrostatic force on the second charge (charge 2) will be away from the first charge (charge 1).

The electrostatic force between the two charges is determined with Coulomb's law;

F = kq²/r²

F = (9 x 10⁹ x 0.0008²)/(2)²

F = 1,440 N

Since the two charges are the same (positive), the direction of the electrostatic force on the second charge (charge 2) will be away from the first charge (charge 1).

The error in the biceps force is determined from the ratio of the precision of the mass measurement and actual mass measurement.

The error obtained in the measurement of the bicep force is determined from the precision measurement of the masses, since the product of mass and acceleration gives the force applied to the biceps.

F = ma = mg

where;

Error percent = (precision/measured mass) x 100%

Error percent = (0.1/50) x 100% = 0.2%

Error percent = (0.1/100) x 100% = 0.1%

Error percent = (0.1/200) x 100% = 0.05%

Error percent = (0.1/500) x 100% = 0.02%

Thus, the error in the biceps force is determined from the ratio of the precision of the mass measurement and actual mass measurement.

When a car accelerates from 15 m/s to 60 m/s in 30 seconds, the acceleration of the car is 1 meter/second².

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Given parameters:

Initial speed: u = 15 m/s.

Final speed: v = 60 m/s.

Time interval: t = 30 seconds.

Then, according to definition of acceleration,

Acceleration of the car = change in speed/ time interval

= ( final speed - initial speed)/time interval

= ( 60 m/s - 30 m/s)/30 seconds

= 1 meter/second²

Answer:

independent variable- concentration of reactants

dependent variable- rate of reaction

Explanation:

A dependent variable is a variable that is placed under test and is measured under the process of a scientific experiment.

An independent variable is a variable that undergoes the change in the experiment performed. This change is done with respect to test the efforts that are observed on the dependent variable.

In the given hypothesis, 'concentration of reactants' is the independent variable and 'rate of reaction' is the dependent variable

Answer:

density = 0.16[gr/cm^3] = 160 [kg/m^3]

Explanation:

To solve this problem we must use the definition of density which tells us that this is equal to the relationship between mass and volume. In this way we have:

Since the body is a cube, its sides are equal we have:

v = 5 * 5 * 5 = 125 [cm^3]

m = 20 [grams]

density = m / v

density = 20/125

density = 0.16 [grams/cm^3]

Now if we convert the units to the international system, we have:

[tex]0.16[\frac{gr}{cm^{3} } ]*\frac{1kg}{1000gr} *\frac{100^{3} cm^{3} }{1^{3} m^{3} } \\= 160 [kg/m^{3} ][/tex]

The equation for kinetic energy of shm system is given by;

KE=0.5mw²(A²-x²)

where m is the mass of the object

w² is the angular frequency

A is the amplitude

and x is the positive

The equation for the potential energy is given by;

PE=0.5mw²x²

Solve KE=2PE and you get ur answer

[tex] \sf{\blue{«} \: \pink{ \large{ \underline{A\orange{N} \red{S} \green{W} \purple{E} \pink{{R}}}}}}[/tex]

Given:

Amplitude [tex]\displaystyle\sf A = 10\,\text{cm} = 0.1\,\text{m}[/tex]

We want to find [tex]\displaystyle\sf x[/tex] such that the kinetic energy [tex]\displaystyle\sf KE[/tex] is twice the potential energy [tex]\displaystyle\sf PE[/tex].

Using the formulas for kinetic energy and potential energy in SHM:

[tex]\displaystyle\sf KE = \dfrac{1}{2}mv^{2}[/tex]

[tex]\displaystyle\sf PE = \dfrac{1}{2}kx^{2}[/tex]

Since we are considering the same particle, the mass [tex]\displaystyle\sf m[/tex] cancels out. Therefore, we can compare the expressions for [tex]\displaystyle\sf KE[/tex] and [tex]\displaystyle\sf PE[/tex]:

[tex]\displaystyle\sf \dfrac{1}{2}kx^{2} = 2\left(\dfrac{1}{2}kA^{2}\right)[/tex]

Simplifying this equation:

[tex]\displaystyle\sf kx^{2} = 2kA^{2}[/tex]

Dividing both sides by [tex]\displaystyle\sf k[/tex]:

[tex]\displaystyle\sf x^{2} = 2A^{2}[/tex]

Taking the square root of both sides:

[tex]\displaystyle\sf x = \sqrt{2}A[/tex]

Substituting the value of [tex]\displaystyle\sf A[/tex]:

[tex]\displaystyle\sf x = \sqrt{2} \times 0.1\,\text{m}[/tex]

Calculating the value:

[tex]\displaystyle\sf x = 0.1414\,\text{m}[/tex]

Converting to centimeters:

[tex]\displaystyle\sf x = 0.1414 \times 100\,\text{cm}[/tex]

[tex]\displaystyle\sf x \approx 14.14\,\text{cm}[/tex]

Therefore, the distance from the mean position at which the kinetic energy is twice the potential energy is approximately [tex]\displaystyle\sf 14.14\,\text{cm}[/tex].

why does something fall faster if it is heavier?

➪ First of all I would like to inform you that this statement is not true. The acceleration does not depend on the mass of the object. Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

Lets see

According to Newton's second law

[tex]\\ \rm\rightarrowtail F=ma[/tex]

[tex]\\ \rm\rightarrowtail F\propto m[/tex]

[tex]\\ \rm\rightarrowtail m\propto \dfrac{1}{a}[/tex]

The compression of 10 cm by a 100 N force on the plane that has a

coefficient of friction of 0.39 give the following values.

Mass of the block, m = 3 kg

[tex]Spring \ constant, K = \dfrac{100 \, N}{0.1 \, m} = \mathbf{ 1000\, N/m}[/tex]

Coefficient of kinetic friction, [tex]\mu_k[/tex] = 0.39

Therefore, we have;

Friction force = [tex]\mathbf{\mu_k}[/tex]·m·g·cos(θ)

Which gives;

Friction force = 0.39 × 3 × 9.81 × cos(48°) ≈ 7.68

Work done by the motion of the block, W ≈ 7.68 × d

The work done = The kinetic energy of the block, which gives;

[tex]\mathbf{\dfrac{1}{2} \times k \cdot x^2 }= 7.68 \cdot d[/tex]

The initial kinetic energy in the spring is found as follows;

K.E. = 0.5 × 1000 N/m × (0.1 m)² = 5 J

The initial velocity of the block is therefore;

5 = 0.5·m·v²

v₁ = √(2 × 5 ÷ 3) ≈ 1.83

Work done by the motion of the block, W ≈ 7.68 N × 0.07 m ≈ 0.5376 J

Chane in kinetic energy, ΔK.E. = Work done

ΔK.E. = 0.5 × 3 × (v₁² - v₂²)

Which gives;

ΔK.E. = 0.5 × 3 × (1.83² - v₂²) = 0.5376

Which gives;

The height at which the block will stop moving, h, is given as follows;

[tex]At \ the \ maximum \ height, \ h, \ we \ have ; \ \dfrac{1}{2} \times 1000 \times 0.1^2 = 7.68 \times x[/tex]

Which gives;

[tex]Length \ of \ the \ incline \ at \ maximum \ height, \ x_{max} =\dfrac{ 7.68 }{ \dfrac{1}{2} \times 1000 \times 0.1^2 } \approx 1.536[/tex]

The distance up the inclined, the block rises, at maximum height is therefore;

[tex]x_{max}[/tex] ≈ 1.536 m

Therefore;

h = 1.536 × sin(48°) ≈ 1.1415

From the above solution for the height, the length of the incline is he

distance along the incline at maximum height which is therefore;
