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 1

Answer:

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:

Answer 2

Answer:

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

A stone is dropped from a height of 7.70 m how fast is it going when it is 5.25 m above the ground

Answers

The velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

Velocity of the stone

The velocity of the stone at the given displacement is calculated as follows;

K.E = ΔP.E

¹/₂mv² = mgh

v = √2gΔh

v = √[2(9.8)(7.7 - 5.25)]

v = 6.93 m/s

Thus, the velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

NASA decides to put a 128 kg satellite into orbit over the planet Venus because they want to take pictures. The satellite is 37,000,000 m above the surface of venus. Calculate the gravitational field at that altitude. m/s2
how do you calculate this

Answers

1). Look up the acceleration of gravity on the surface of Venus. It's 8.87 m/s².
(That's about 10% less than on Earth.)

2). Look up the radius of Venus. It's 6051.8 km.
(That's about 5% less than Earth's.)

3). Remember that the gravitational field (acceleration, force) changes
opposite to the square of the distance from the planet ... or the distance
between any two masses that are gravitating.

Now we have enough information to do the calculating. Notice that the question
only asks for the planet's "gravitational field" (acceleration) way out there. That
has nothing to do with the satellite's mass, or whatever you decide to put out there,
or even if there's nothing out there at all. It's just a characteristic of Venus at that
distance from it.

The distances we need to compare are the distances from the center of Venus.

On the surface (distance from the center is the radius of Venus), it's 6,051,800 m.
In the orbit, it's 37,000,000 m.

The ratio is (37,000,000 / 6,051,800) = about 6.1 .

The gravity way out in the orbit is less than on the surface, and by the
same amount as the square of the distance ratio.

Surface gravity = 8.87

Gravity out at the orbit = 8.87 divided by (the distance ratio)²

Gravity = 8.87 / (6.1)²

Better way: Gravity = 8.87 x (6,051,800/37,000,000)² = 0.2373 m/sec²

What is the momentum of a 52 kg carton that slides at 5.0m/s across an icy surface?

Answers

Formula for momentum is mass times velocity so you do 52 kg times 5 m/s and that equals 260 kg x m/s
