A student squeezes several oranges to make a glass of orange juice. The juice contains pieces of orange pulp mixed with the juice. Explain why this drink can be considered a combination of a suspension and a solution.

Answers

Answer:

The juice contains sugars, plant pigments, and other chemicals dissolved in water. This is a solution. The pieces of orange pulp will rise to the top or settle to the bottom of the juice if it is allowed to sit. The pieces of pulp mixed with the juice form a suspension.

Explanation:

In chemistry, a suspension is a heterogeneous mixture containingsolid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer. A Suspension is a heterogeneous mixture in which the soluteparticles do not dissolve but get suspended throughout the bulk of the medium.a solution is a homogeneous mixture composed of two or moresubstances. In such a mixture, a solute is a substance dissolved in another substance, known asa solvent.. it is considered a solution andsuspension because the orange juice mix with water while the pulp did not andretained as solid

The amplitude of a transverse wave on a string is 3.0 cm. The ratio of the maximum particle speed to the speed of the wave is 3.9. What is the wavelength (in cm) of the wave?

Answers

Answer:

Therefore the wavelength of the particle is 4.83 m.

Explanation:

Transverse wave: A transverse wave is a moving wave whose direction of wave and oscillation are perpendicular to each other.

Amplitude:The amplitude of a wave is the maximum the distance from its rest position covered by a particle.

Here amplitude (A) = 3.0 cm

The ratio of maximum speed to the speed of the particle is 3.9

The maximum speed of the particle $C_(max)$ = A×ω

The speed of the particle C= f×λ

Then,

$(C_max)/(C) =(A* \omega)/(f* \lambda)$

$\Rightarrow (C_max)/(C) =(A* 2\pi * f)/(f* \lambda)$ [∵ω=2πf]

$\Rightarrow (C_max)/(C) =(A* 2\pi )/( \lambda)$

$\Rightarrow 3.9=(3* 2\pi )/( \lambda)$

$\Rightarrow \lambda=(3* 2\pi )/( 3.9)$

$\Rightarrow \lambda = 4.83$ m

Therefore the wavelength of the particle is 4.83 m

PLEASE HELP!! Use the information below to solve this problem: A note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, what pitch is this note? speed of sound in air: 343 m/s

A. 440.00 Hz
B. 493.88 Hz
C. 523.25 Hz
D. 587.33 Hz
E. 659.26 Hz
F. 698.46 Hz
G. 783.99 Hz

Answers

Answer:

Explanation:

Given that a note has a wavelength of 0.65551 m. If the speed of sound is 343.00 m/s, the pitch of the note is the same as the frequency.

Sound Velocity = product of frequency and wavelength.

Substitute wave speed and wavelength into the formula

343 = f × 0.65551

Make f the subject of formula

F = 343 / 0.65551

F = 523.58 Henz

Therefore, the pitch of the note is 523.52 Hz approximately

The correct answer is option C

Which of the following is the best example of Newton's second law? A. A rolling ball comes to a stop because the forces of friction and gravity are acting upon it. B. The acceleration of a skydiver depends upon the force of gravity and wind resistance. C. As a boat propeller forces water in one direction, the boat moves in the opposite direction. D. When a basketball strikes the ground, the ground exerts an upward force on the basketball.

Answers

Answer:

B. the acceleration of a skydiver depends upon the force of gravity and wind resistance

Explanation:

Newtons second law of motion states that: the force (F) acting upon an object is directly proportional to the mass (M) of the object and the acceleration (a).

Basically this law states that the acceleration of a body is dependent on the force and mass of the body. If the force exerted on the body changes the acceleration will also change. and if the mass of the body changes, the acceleration will also be affected

from the options, the only option that refers to acceleration is option B

Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. He turned the car one more time and went 35 meters east. His car was 15 meters from the starting line. This took 5 seconds.What is the car’s velocity?
A. 3 m/s west

B.3 m/s east

C. 19 m/s west

D. 19 m/s east

Answers

Although the car's average speed is 19 m/s ,
its velocity is 3 m/s east.

Velocity is (displacement) / (time)

and Displacement is the distance between the start point and
end point, no matter what route was traveled between them.

In this case, the displacement is 15 meters east.
So the velocity is

(15 meters east) / (5 sec) = 3 meters/sec east .
