Answer: Mechanical wave travels slowest in gases.

Explanation:

Mechanical wave is a wave in which there is a oscillation of the matter. Therefore, there is a transfer of the energy through the medium.

The wave travels over long distances. Mechanical waves are of two types: Longitudinal wave and Transverse wave. Mechanical wave requires a medium to travel. It can travel in the solid, liquid and gases.

It travels fastest in solid and slowest in the gases due to the packaging of the molecules of the state. The molecules of the gases are not tightly packed so therefore it is hard for the particle to transfer energy.

Through gases as the bonds are tightly bound. Mechanical waves travel by vibrating through the medium so the more tight the bonds , the faster the waves.

A 2.0 kg block is given an initial speed of 8.0 m/s up an incline plane of angle 30° where the coefficient of friction is 0.35.

Korvikt [17]

Answer:

4.1 m

Explanation:

Given :

Mass of the block = m = 2 kg.

Initial velocity = $v_{i}$ = 8 m/s

Angle of the incline = α = 30°

Coefficient of friction = μ = 0.35

Distance moved up the incline is calculated using the work energy theorem.

Work done by the net force = change in kinetic energy of the object.

Net work = work done by friction + work done by the gravity component.

(- mg sin 30 - μ mg cos 30 ) d = $1/2m v_{f}^{2} - 1/2 m v_{i}^{2}$

m cancels out when divided on both sides with m.

- [(9.8 sin 30 - ( 0.35 × 9.8 × cos 30) ] d = 1/2 ( 0² - 8² )

⇒ -7.87 d = -32

⇒ Distance traveled up the incline = d = 4.0658 m = 4.1 m

A small boat is moving at a velocity of 1.93 m/s when it is accelerated by a river current perpendicular to the initial directio

olasank [31]

Answer:

16.405m/s

Explanation:

Given, initial velocity = u = 1.93m/s, acceleration = a = 0.750m/s2, time = t = 19.3s, final velocity = v= ?

Using the first equation of linear motion,

v = u + at

v = 1.93 + 0.750 x 19.3

v = 1.93 + 14.475

v = 16.405m/s

In simple harmonic motion, the acceleration is proportional to In simple harmonic motion, the acceleration is proportional to:__

erik [133]

Answer:

e. all of the above

Explanation:

In simple harmonic motion, the acceleration is given as;

a = -ω²x = -(2πf)²x

$a_{max} = -\omega ^2A$

where;

ω is the angular velocity

f is the frequency

x is the displacement

A is the amplitude

Thus, In simple harmonic motion, the acceleration is proportional to the amplitude, velocity, frequency, and displacement.

The correct option is E.

"all of the above"
