At 30 degrees C, 90 grams of NaNO3 is dissolved in 100
grams of water. Is this solution SATURATED,
UNSATURATED, BOTH, or NEITHER
Answers
At 30 degrees C, when 90 grams of NaNO3 is dissolved in 100 grams of water, the solution becomes UNSATURATED.
A saturated solution is a solution that doesn't completely dissolve the solute.
An unsaturated solution is a solution that has a lesser amount of solute than the saturated solution in which it is being dissolved. Thus, the solute will be completely dissolved in the solution at the end of the reaction process.
From the given information:
NaNO3(salt) is the solutewater is the solvent.Since the mass of the solute is lesser than the solvent. It implies that the solute will dissolve completely in the solvent.
Therefore, the solution becomes unsaturated.

How much energy is transferred when the potential difference is 12V and the charge is 7.5C?
Answers
The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.
What is energy?
In physics, energy is the capacity to carry out work. It might be potential, kinetic, thermal, electrical, chemical, radioactive, etc., among other types. Heat and work are other examples of energy being transferred from one body to another. Once it has been transmitted, energy is always allotted according to its nature. As a result, heat transmission could result in thermal energy while effort could provide mechanical energy.
Given the information in the question:
The potential difference, V = 12 Volts,
The charge, q = 7.5 C,
Calculate the energy, E by the formula given below,
E = [tex]VQ[/tex]
Substitute the values of charge and potential difference,
E = [tex]12*7.5[/tex]
E = [tex]90 Joules[/tex]
Therefore, the energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

Answers
Answer:
E_g = m 392 J, Ek = m 392
Explanation:
Mechanical energy is a very important concept since if the system does not have friction it remains constant
the potential energy of a system is
E_g = U = m g (y2 - i)
E_g = m 9.8 (40 -0)
E_g = m 392 J
The kinetic energy for this system assuming it started from rest
E_k = K = ½ m v2
how mechanical energy is conserved
E_g = E_k
Ek = m 392

Preview this picture of a roller coaster. Does it make you feel safe? How does the picture reinforce the idea of roller coasters being safe as stated in the article?
Answers
Answer: The coaster tracks serve to channel this force — they control the way the coaster cars fall. ... If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt-up, gravity applies a downward force on the back of the coaster, so it decelerates.

Which electrical device operates because of this effect?ics exam someone please help 9th grade &
Answers
Answer:
Generator.
Explanation:
In a generator, an e.m.f. is induced across a wire when it moves through the magnetic field between the poles of a magnet.
The mode of operation of a generator is that a metal core with copper tightly wound to it (conductor coil) rotates rapidly between the two (2) poles of a horseshoe magnet type. Thus when the conductor coil rotates rapidly, it cuts the magnetic field existing between the poles of the horseshoe magnet and then induces the flow of current.

The electric field intensity between two large,

plates are 0.05 m apart. What is the electric poten-
tial difference between them?
Answers
Answer:
300 is the answer
Explanation:
Hope that this answer will help you
The electric potential difference between the two large, charged parallel metal plates is 300 V.
What is the potential difference?The electric potential difference (V) between two points is defined as the work done per unit charge in moving a positive test charge from one point to another.
Mathematically,
V = W/Q
where W is the work done in moving the charge Q between two points.
Here in the Question,
In the case of two large, charged parallel metal plates, The electric field intensity (E) is given as 6000 N/C and the distance between the plates (d) is 0.05 m. The electric field intensity between the plates is uniform, which means that the force on a test charge is constant at any point between the plates.
The work done (W) in moving a positive test charge from one plate to the other against the electric field is given by
W = F × d
where F is the force acting on the test charge and d is the distance moved.
Using the formula for electric field intensity
E = F/Q
we can express force:
F = QE
Substituting this in the formula for work done, we get
W = Q × E × d.
Now, the electric potential difference (V) between the plates is given by
V = W/Q = E × d = 6000 N/C × 0.05 m = 300 V.
V = 300 V
Therefore, the electric potential difference between the two large, charged parallel metal plates is 300 V. This means that if a positive test charge is moved from one plate to the other, the work done in moving it against the electric field is 300 J per coulomb of charge.

A scientist is studying a newly created substance. She performs a test in which she keeps adding heat to the substance until it catches on fire. What type of property is she measuring?
Answers
Answer:
Chemical property (flammability).
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In this scenario, a scientist is studying a newly created substance. She performs a test in which she keeps adding heat to the substance until it catches on fire. Thus, the type of property she is measuring is a chemical property (flammability).
Flammability can be defined as a chemical property which measures the ability of a substance (matter) to ignite or burn due to the presence of oxygen and heat.
