Waves transfer _________________, not the _____________ with it. A ______________________ causes particles in matter to move bac

k and forth at right angles to the direction in which the wave travels. High points in a transverse wave are called ________________. Low points are called ________________. A ________________ wave causes particles in matter to move back and forth along the same direction in which the wave travels. The places in a longitudinal wave in which the coils are squeezed together are called ______________. The places in the wave in which the coils are spread apart are called _________________. The ________________ of a transverse wave is the distance between two adjacent crests or two adjacent troughs. The _________________ of a compressional wave is the distance between two adjacent compressions or rarefactions.. The _____________ of a wave is the number of wavelengths that pass by a point each second. Frequency is measured in units of _____________. The ___________ of a wave depends on the medium in which the wave travels. To make a wavelength of rope shorter, one should shake the rope at a ____________ frequency. The speed of a wave can be found using the equation ________________. As the wavelength of a wave increases, the frequency of the wave _______________. The energy of a wave depends on its ______________________.

1.A particle is moving up an inclined plane. Its velocity changes from 15m/s to 10m/s in two seconds. What is its acceleration?
FrozenT [24]

\huge{ \underline{ \boxed{ \bf{ \blue{Solution:}}}}}

<h3><u>Provided</u><u>:</u><u>-</u></h3>
  • Initial velocity = 15 m/s
  • Final velocity = 10 m/s
  • Time taken = 2 s

<h3><u>To FinD:-</u></h3>
  • Accleration of the particle....?

<h3><u>How</u><u> </u><u>to</u><u> </u><u>solve</u><u>?</u></h3>

We will solve the above Question by using equations of motion that are:-

  • v = u + at
  • s = ut + 1/2 at²
  • v² = u² + 2as

Here,

  • v = Final velocity
  • u = Initial velocity
  • a = acceleration
  • t = time taken
  • s = distance travelled

<h3><u>Work</u><u> </u><u>out</u><u>:</u></h3>

By using first equation of motion,

⇛ v = u + at

⇛ 10 = 15 + a(2)

⇛ -5 = 2a

Flipping it,

⇛ 2a = -5

⇛ a = -2.5 m/s² [ANSWER]

❍ Acclearation is negative because final velocity is less than Initial velocity.

When a 100-N force acts horizontally on an 8.0-kg chair, the chair moves at a constant speed across the level floor. Which state
TiliK225 [7]

Answer:

The applied force is greater than the frictional force.

Explanation:

the chair moves at <u>a constant speed</u><u> </u><u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>not</u><u> </u><u>A</u><u> </u><u>or</u><u> </u><u>C</u><u>.</u>

if there is no friction then the chair <u>would accelerate and it would not be at a constant speed</u><u>.</u>

hence, the only possible answer is B.
