The work done to compress a spring with a force constant of 290.0 N/m a total of 12.3 mm is: a) 3.57 J b) 1.78 J c) 0.0219 J d)

iren2701 [21]

Answer:

Work done, W = 0.0219 J

Explanation:

Given that,

Force constant of the spring, k = 290 N/m

Compression in the spring, x = 12.3 mm = 0.0123 m

We need to find the work done to compress a spring. The work done in this way is given by :

$W=\dfrac{1}{2}kx^2$

$W=\dfrac{1}{2}\times 290\times (0.0123)^2$

W = 0.0219 J

So, the work done by the spring is 0.0219 joules. Hence, this is the required solution.

a sound wave is determined to have a frequency of 1,000 hz and wavelength of 35cm. what is the speed of this wave?

natulia [17]

Answer:

The speed of the sound wave is 350 m $s^{-1}$

Explanation:

Given

Frequency of sound wave = 1000Hz = 1000 $s^{-1}$ (since 1 $s^{-1}$ = 1 Hertz (Hz))

Wavelength of sound wave = 35 cm

Speed of sound wave = ?

All waves have same the relation among frequency, sound and speed which is given by

v=fλ , where

v is the speed

f is frequency

λ is wavelength

Therefore, the speed of sound wave = 1000 $s^{-1}$ x 35 cm

= 35000 cm $s^{-1}$

= 350 m $s^{-1}$

Hence the speed of the sound wave is 350 m $s^{-1}$

The amount of movement of the particles depends on the amount of _________ acting on them and their relationship to other atoms.

Liula [17]

Answer: The amount of movement of the particles depends on the amount of <u>force</u> acting on them and their relationship to other atoms.

Explanation:

The inter-atomic force determines the inter-atomic distance which governs the amount of movement of the particles.

For example in solids, the inter-atomic force is stronger and hence, the distance between any atoms is very very small which restricts the movement of the particles. On the other hand, in case of liquids and gases, the inter-atomic forces are not very strong and there is more distance between the atoms which allows free movement of particles.

How does a arrow represent displacement

Lera25 [3.4K]

Answer:

An arrow represents displacement. Because it's a vector quantity.

Vector quantity= Direction+Magnitude

When an arrow is put above a unit like

acceleration
displacement

it means that it's a vector quantity.

Hope this helps ;) ❤❤❤
