Answer:

a)

Explanation:

As the visible light, infrared and radio waves are all electromagnetic waves with different frequency and wavelength, all of them propagate through the space at the same constant speed which is the speed of light in vacuum, as they meet the following equation:

c = λ*f

Learning Task 3: Read the characteristics of mixtures given in the second column. Identify if it is homogeneous or heterogeneous
madreJ [45]

1. Components can be separated by physical means  [heterogenous]

2. The additive component is so<em> </em>finely dispersed in the main ingredient   such that it can't be seen  [homogenous]

3. Particles are uniformly distributed  [homogenous]

4. The substances are identified in<em> </em>different phases  [heterogenous]

5. Particles are<em> </em>non-uniformly distributed  [heterogenous]

A homogenous mixture is a type of mixture in which the composition is uniform throughout the mixture.

Characteristics of a homogenous mixture:

  • the mixture is uniform
  • the composition is the same
  • it consists of one phase

A  heterogenous mixture is a type of mixture in which the composition of the mixture is not uniform

Characteristics of heterogenous mixture include;

  • it contains two or more ingredients or phases.
  • different phases mixed together, which are physically separated  
  • samples obtained from different parts of the mixture may have a different composition

In the given characteristics of the mixture  in the question we can classify them as follows;

1. Components can be<u> separated by physical mean</u>s --heterogenous

2. The additive component is so<em> </em><u>finely dispersed </u>in the main ingredient   such that it can't be seen --- homogenous

3. Particles are<u> uniformly distributed </u>---- homogenous

4. The substances are identified in<em> </em><u>different phases</u> ---- heterogenous

5. Particles are<em> </em><u>non-uniformly distributed </u>---- heterogenous

1. Some ripples spread across a pond with a frequency of 5 Hz. How much would be the period of these ripples.
Scilla [17]

1)The period of these ripples will be 0.2 sec.

2)The time period of sound wave will be 100 Hz.

3)The frequency of the sound wave will be 5×10⁶ Hz.

<h3>What is frequency?</h3>

Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.

Frequency is given by the formula as,

Frequency of  ripples (f₁)=5 Hz

The period of these ripples will be;

T₁=1/f₁

T₁=1/5

T₁=0.2 sec

The time period of sound wave (T)=0.01 seconds

The time period of sound wave;

f=1/T

f=1/0.01

f=100 Hz

Time period of A radio wave = 0.0000002 seconds

The frequency of the sound wave is;

f=1/T

f=1/0.0000002

f=5×10⁶ Hz

Hence,the period of these ripples will be 0.2 sec.

A car is accelerating when it is:________.
Jet001 [13]

Answer: A car is accelerating when it is traveling on a straight uphill road at 30 miles per hour.

Explanation:

Acceleration is the change in velocity of an object with respect to time. For a body to accelerate, its velocity must be changing at every time interval. According to option a and c, the velocity of the body is constant during the journey but the time is changing. A body with constant velocity possesses a zero acceleration.

A car travelling on a straight up hill possesses velocity change at each time interval. Since the car is on a slope, its shows its acceleration is changing.
