Sugar dissolved in water is an example of?
lbvjy [14]

Answer:

D. Solution

Explanation:

Sugar dissolved in water is an example of solution.

A solution is a homogenous mixture of solutes and solvents.

In a solution the solute particles ae distributed uniformly in the solvents. The solute is the substance and it is the sugar here that is dissolved to make a solution.

The solvent is the water in this instance that helps to dissolve the solute.

. You are sitting on a beach watching the waves roll in. In 12 seconds, 6 waves roll by. What is the period of the waves (7)? Wh
Andrew [12]

Answer:

Explanation:

6 waves in 12 seconds

The period of a wave is defined as the time taken by the wave to complete one oscillations.

Here, 6 waves are completed in 12 seconds

So, one wave is completed in 2 seconds

So, the period of the wave is 2 second.

frequency is defined as the number of waves completed in one second. It is the reciprocal of period of the wave.

frequency = 1 / 2 = 0.5 Hertz

Let the wavelength is λ.

f = 660  kHz = 660000 Hz

the relation for the wave speed and the wavelength and the frequency is given by

v = f λ

where v is the speed of wave = 3 x 10^8 m/s

So, 3 x 10^8 = 660000 x λ

λ = 454.55 m

A constant force of 53 newtons was applied to a 12-kilogram mass for 15 seconds. a.) What was the change in momentum of the mass
vazorg [7]

Explanation:

Impulse = change in momentum

FΔt = Δp

(53 N) (15 s) = Δp

Δp = 795 kg m/s

For constant mass:

Δp = m Δv

795 kg m/s = (12 kg) Δv

Δv = 66.25 m/s

Rounding to two significant figures, Δp = 800 kg m/s and Δv = 66 m/s.

Why do you expect the last color of the sunset to be on the red end of the visible spectrum?
Harlamova29_29 [7]

We expect the last colour of the sunset to be on the red end of the visible spectrum because of the dispersion of light.  Due to the particles present in the atmosphere, the light rays undergo scattering and the light of shorter wavelengths like blue gets dissipated but light rays of longer wavelengths travel long distances without getting dissipated.

Dispersion of light is the phenomenon in which the light from the sun is split into its constituent colours which are Violet, Indigo, Blue, Green, Yellow, Orange, and Red when it passes through a prism or due to the particles present in the earth's atmosphere.

Two skaters begin at rest. Skater 1 has a smaller mass than Skater 2. After they push off each other,...
klasskru [66]

As both the skater pushed each other with a force, skater 1 will acquire greater velocity than skater 2 with heavier mass.

Answer: Option C

<u>Explanation:</u>

Here we can understand the scenario with the example of a particle collision. When two particles of different masses, one being lighter and the other being heavier, there will be a movement and change in velocities.

Now, when these two particle collide with each other, there will be an equal and opposite thrust or reaction on both the particles. The particle with heavier mass will not be able to acquire more velocity because of its weight whereas the lighter particle will be pushed far away, being less in mass.

We can also say that the heavier particle will exert more force as compared to the lighter one and hence, can easily push it far away. this is all because the force is directly proportional to the mass of the object.

Hence, just like the particle, when two skater try to push each other with a significant amount of force, skater 2 will win to exert more force and therefore, skater 1 will acquire greater velocity as compared to skater 2.
