Answer:In physics, motion is defined as a change in the position of a body with respect to a reference point. ... Think about the motion of three cars: one in the fast-moving carpool lane, another in the middle lane, and the third in the slow lane used to enter or exit the freeway.

A steel cable has a cross-sectional area 2.54 10-3 m2 and is kept under a tension of 1.01 104 N. The density of steel is 7860 kg

ElenaW [278]

Answer:

The speed is equals to 22.49 m/s

Explanation:

Given Data:

$Area = A=2.54*10^-^3m^2\\Force = F = 1.01*10^4N\\density = p = 7860 kg/m^3$

Required:

Speed of Traverse wave = c =?

Solution:

As we know that

$p=m/V\\\\ p=m/(L*A)\\p*A=m/L$

Now the equation for speed of traverse wave is calculated through:

$\sqrt \frac{F*L}{m}\\$

= $\sqrt\frac{F}{m/L} \\\sqrt{} \frac{F}{p*A}$

Substituting the values

$\sqrt\frac{1.01*10^4}{7860*2.54*10^-^3} \\$

=22.49 m/s

Amplitude and energy are inversely related, meaning that a high-energy wave has low amplitude and a low-energy wave has high amp

Elodia [21]

According to the physical fact that a<span>mplitude and energy have proportional values, this statement is definitely FALSE. Pay attention on the words ''</span><span> inversely related'', that will be the main point which will make it absolutely clear. Hope you will find this answer helpful! Regards.</span>

A large truck is moving 22.0 m/s. If it’s momentum is 125,000 kg • m/s, what is the trucks mass

strojnjashka [21]

Answer:

p = mv

m = p/v = 125000/22 = 5682 kg

Explanation:

Direct application of the momentum equation

p = mv

where,

p: momentum

m: mass

v: object velocity

steps:

-------

1) check for units consistency ( SI or Imperial)

2) separate the variable you are looking for.

3) DONE! :DD

Two people pull on a horizontal spring that is attached to an immovable wall. Then, they detach it from the wall and pull on opp

zimovet [89]

Answer:In first case

Explanation:

When two People pull the spring, let the applied force by each person be $F_o$

and spring constant of spring be k

so Total force is $2F_o$

total extension according to Hooke's law is

$x=\frac{2F_o}{k}$

When they detach the spring and apply force in opposite direction then force on either side is F so net extension is

$x'=\frac{F_o}{k}$

so in first case there will be more extension
