A clever engineer designs a "sprong" that obeys the force law fx =−q(x−xe)3, where xe is the equilibrium position of the end of the sprong and q is the sprong constant. for simplicity, we'll let xe =0m. then fx =−qx3.

Answers

The unit of q is N/m³.While the potential energy of the compressed spring will be $\rm U(x)= -(qx^4)/(4)$ .

What is the potential energy of spring?

When a springdeviates from its mean position, it attempts to regain equilibrium by applying a force that is equivalent to but opposite to the external force.

Spring force has been used in bicycle carriers and launchingmechanisms, where the energy generated by disrupting the spring'sbalance is used as potential energy.

The given equation for the force law is;

$\rm f_x =-q(x-x_e)$

Where,

$\rm x_e$ is equilibrium position of the end of the spring

q is a spring constant

If at equilibriumposition;

$\rm x_e=0$

$\rm F_X= -qx^3 \n\n \rm q = (F_x)/(x^3) \n\n$

So the unit derived will be;

q = N/m³

The potential energy of the spring is found by;

$\rm F_x=- (du)/(dx) \n\n U(x)= -\int\limits^x_0 {F(x)} \, dx \n\n U(x)= -\int\limits^x_0 -qx^3 \, dx \n\n U(x)=- (qx^4)/(4)$

Hence the unit of q is N/m³.While the potentialenergy of the compressed spring will be $\rm U(x)= -(qx^4)/(4)$ .

The objective of this question is to compute the units of q and calculate the expression for the P.E of the compressed spring

Answer:

q = N/m³

$\mathbf{U(x) = -(qx^4)/(4)}$

Explanation:

Given that:

The equation for the force law is:

$F_x = -q (x -x_e)^3$

where;

$x_e$ e = equilibrium position of the end of the spring

i.e. $x_e$ = 0

q = is the spring constant

Also;

$F_x = -qx^3$

From above the units of q can be calculated by making q the subject of the formula :

$q = (F_x)/(x^3)$

where x is in meters and F is in Netwon;

Then :

q = N/m³

The Potential energy P.E of the compressed spring can be calculated by using the integral:

$F_x = -(dU)/(dx)$

$U(x) = - \int F_x dx$

$U(x) = - \int ^x_0 (-qx^3) \ dx$

$\mathbf{U(x) = -(qx^4)/(4)}$

Answers

Little is known about much of earth’s early history because Precambrian rocks have been deeply buried they have been changed by heat and pressure ,Precambrian soft-bodied life-forms weren’t often preserved as fossils.

What is Precambrian rocks?

The Precambrian is the earliest part of Earth's history, set before the current Phanerozoic.

Why are Precambrian rocks rare?

Fossils are rare in Precambrian rocks mostly because Precambrian life-forms lacked bones, or other hard parts that commonly form fossils.

During a race, a horse's speed increases from 65 m/s to 73 m/s during the last 5.0 seconds of that race What was the rate of acceleration during this time?

Answers

During a race, a horse's speed increases from 65 m/s to 73 m/s during the last 5.0 seconds of that race, 1.60 m/s² was the rate of acceleration during this time.

What do you mean by an acceleration ?

The rate of change of velocity is defined as acceleration. Acceleration usually indicates that the speed is changing, but this is not always the case. When an object moves in a circular path at a constant speed, it is still accelerating because its velocity direction changes.

Acceleration occurs when the speed of an object increases or decreases, or when it changes direction. Acceleration, like velocity, has two types: average and instantaneous.

a = v - v₀ / t

Then, a = 73 × 65 / 5

a = 1.60 m/s²

Thus, 1.60 m/s² was the rate of acceleration during this time.

A metal object is suspended from a spring scale. The scale reads 930 N when the object is suspended in air, and 731 N when the object is completely submerged in water. Find the volume of the object. The acceleration of gravity is 9.8 m/s 2 . Answer in units of m3 .

Answers

Answer:

The volume of the object = 0.0203 m³

Explanation:

From Archimedes principle,

Upthrust = lost in weight = amount of water displaced.

U = W₁ - W₂

Where U = upthrust, W₁ = Weight in air, W₂ = weight in water.

U = 930- 731

U = 199 N.

but mass of water displaced,

m = U/g where g = 9.8 m/s²

m = 199/9.8

m = 20.31 kg.

Recall,

Density = mass/volume.

Density of water = mass of water displaced/ volume of water displaced

D = m/V

V = m/D......................................... Equation 1

Where V = volume of water displaced, m = 20.31 kg, D = 1000 kg/m³

Substitute into equation 1

V = 20.31/1000

V = 0.0203 m³

the volume of water displaced = 0.0203 m³

Note: That when an object is immersed in water, the volume of water it displaced is equal to it's volume.

Hence, Volume of water displaced = volume of the object.

Hence the volume of the object = 0.0203 m³
