A(n) is a line in which waves that are moving together are all in the same phase.

1 answer:

5 0

The line in which waves that are moving together are all in the same phase is referred to as the wave front.
For example, in a series of waves, all of the crests that are in a single line make up a single wave front. This is the case for every set of particles at the same specific point in a series of waves.

A balloon is filled with a gas at 111 kPa when the temperature was 22*C. If the temperature

storchak [24]

119.7kPa

Explanation:

Given parameters:

Pressure of gas in balloon = 111kPa

Temperature of gas = 22°C

Final temperature = 45°C

Unknown:

Final pressure = ?

Solution:

Since the gases in the balloon have the same number of moles. We can apply a derivative of the combined gas law to solve this problem.

At constant volume the pressure of a given mass of gas varies directly with the absolute temperature.

$\frac{P1}{T1} = \frac{P2}{T2}$

P1 is the initial pressure

P2 is the final pressure

T1 is the initial temperature

T2 is the final temperature

convert from celcius to kelvin:

tK = 273 + tC

T1 = 273 + 22 = 295K

T2 = 273 + 45 = 318K

$\frac{111}{295} = \frac{P2}{318}$

P2 = 119.7kPa

A block is at rest. The coefficients of static and kinetic friction are s = 0.81 and k = 0.69, respectively. The acceleration of

lys-0071 [83]

Answer:

Explanation:

a ) The angle required = angle of repose = θ

Tanθ = .81

θ = 39⁰

b ) when angle of incline θ = 44

Net force on the block = mg sinθ - μ mg cosθ where μ is coefficient of kinetic friction

acceleration = gsinθ - μ g cosθ

= 9.8 ( sin44 - μ cos44 )

= 9.8 ( .695 - .69 x .72 )

= 9.8 ( .695 - .497 )

= 1.94 m /s²

A tuning fork vibrates at a frequency of 512 hertz

Naily [24]

Answer: The correct answer is " longitudinal wave with air molecules

vibrating parallel to the direction of travel".

Explanation:

In longitudinal wave, the particles vibrate parallel to the direction to the propagation of the wave. For example, sound wave is a longitudinal wave.

It needs a medium for its propagation. It can travel in solid, liquid and gas. It travel faster in solid in comparison to the liquid.

In the given problem, a tuning fork vibrates at a frequency of 512 hertz when struck with a rubber hammer. The sound produced by the tuning fork will travel through air. Here, a longitudinal wave with air molecules vibrating parallel to the direction of travel.

Therefore, the correct option is (1).
