The electricity went out at José's home, and he lit some candles until the lights came back on. The candle wax near the wick became soft right away, and melted over a temperature range. Which term best applies to the candle wax?
Answer:
A.Amorphous solid
Explanation:
There are two states used to describe solids in science; these are crystalline and amorphous (non-crystalline) solids.
Crystalline solids are solids whose constituent particles are properly arranged in a 3-dimensional structure in a crystal-like manner. They have a definite melting point and a defined shape and pattern. A common example of a crystalline solid is diamond.
Amorphous or non-crystalline solids are the opposite of the crystalline solids as there constituent particles are disorderly arranged. They do not have a defined melting point as they melt over a range of temperature.
From the above, it can be deduced that candle wax exhibits the properties of amorphous solids. give me brainliest please
A car with an initial speed of 4.30 m/s accelerates at a rate of 3 ms^2. What is the car's speed after 5 s?
Answer:
v = u + at
u = 4.30 m/s
a = 3 m/s^2
t = 5 s
v = 4.30 + (3)(5)
v = 4.30 + 15
v = 19.30 m/s

The ossicles (the three tiny bones in the middle ear) are responsible for __________.
A.
converting sound vibrations into neural signals
B.
relaying sound vibrations to the eardrum
C.
vibrating in response to sound waves
D.
amplifying sound vibrations from the eardrum
Answer:
D
Explanation: Ossicles amplify the vibrations from the eardrum and transmit them to the inner ear. So the answer is D!
Good luck!
The ossicles (the three tiny bones in the middle ear) are responsible for amplifying sound vibrations from the eardrum. Hence, option (D) is correct.
What are the ossicles in human body?The auditory ossicles, the smallest bones in the body, are three bones in each middle ear that function as a unit to carry soundwaves to the inner ear, playing a crucial role in hearing.
From the tympanic membrane (eardrum) to the oval window, which divides the middle ear from the inner ear, the malleus, incus, and stapes create an interconnected chain. These bones are usually referred to by their shapes, the hammer, anvil, and stirrup, respectively.
The eardrum vibrates as sound passes through the ear canal. The ossicles transmit the vibration to the cochlea, an inner ear organ filled with fluid that turns the vibration into electrical signals that the brain can understand.

if you stand three feet in front of a plane mirror, how far away would you see yourself in the mirror
a. 1.5ft
b. 3.0ft
c. 6.0ft
d. 12ft
Answer:
6 ft
Explanation:
A plane mirror shows you at the actual distance from the mirror, so if a person stood right next to the mirror, he/she will see your image at a distance of 3 feet but since you are at a distance of 3 ft away from the mirror and the image formed is 3 ft inside the mirror
The image will be at a distance of 6 feet from you
Two cars, C and D, travel in the same direction on a long, straight section of highway. During a particular time interval Δt0, car D is ahead of car C and is speeding up while car C is slowing down 07 During the interval Δt0, it is observed that car C gains on car D (i.e., the distance between the cars decreases). Explain how this is possible, and give a specific example of such a case.
Answer:
Car C increases it velocity
Explanation:
From the problem statement, we can see that the two cars all along maintained the same velocities, even though car D was ahead, but at the said time, car C gained on car D, hence the velocity of car C increased more than that of car D, that was why the gap decreased.
A good way to exemplify this is to picture a friend stylishly waiting for you at a distance to meet with them, but they did not stop moving, they reduced their pace, you might have to increase your pace to meet with them, now you can observe the distance between you and them closes
Is the current in the negative battery terminal the same as in the positive battery terminal?
Answer:
Battery between the positive and negative terminals, this charge is often positive ions.
Explanation:
Answer:
Hello
Yes.This potential difference gives rise to an electric field within the wires and the other elements of a circuit. It is also important that charge flows within the battery between the positive and negative terminals – this charge is often positive ions.
Thus both the sides of battery has Positive ions.
What is the gauge pressure of a basketball when you push it down with a force of 30 N, the ball flattens out, and its bottom forms a circular area with a diameter of 2.5 cm? *
Answer:
32.5 N
Explanation:
In displacing a body 5 m by the force of 50 n the work done is 125 j. Find out the angle between the directions of force and displacement
Explanation:
We know,
W=Fscos0
F=50N
S=5m
W=125J
125=50×5×cos0
cos0=125/250=0.5
Thus,
0=cos^-1(1/2)=60°
Thus the angle between force and dicplacement is 60°..

A 30.0 kg box hangs from a rope. What is the tension (in N) in the rope if the box has an initial velocity of 2.0 m/s and is slowing down at 2.0 m/s2?
Answer:
360 N
Explanation:
m = 30kg u = 2 m/s a = -2m/s/s
Since the object has an initial velocity of 2 m/s and acceleration of -2 m/s/s
the object will come to rest in 1 second but the force applied in that one second can be calculated by:
F = ma
F = 30 * -2
F = -60 N (the negative sign tells us that the force is acting downwards)
Now, calculating the force applied on the box due to gravity
letting g = -10m/s/s
F = ma
F = 30 * -10
F = -300 N (the negative sign tells us that the force is acting downwards)
Now, calculating the total downward force:
-300 + (-60) = -360 N
Hence, a downward force of 360 N is being applied on the box and since the box did not disconnect from the rope, the rope applied the same amount of force in the opposite direction
Therefore tension on the force = 360 N
Which of the following is an example of Newton’s first law of motion?
You didn't provide any work but here.
Explanation: Place a ball in a box and slowly push the box. Abruptly stop the box. The ball will keep moving. According to Newton's first law, an object in motion tends to stay in motion unless acted upon by an unbalanced outside force, so the ball keeps rolling even though the box has stopped.

.
What is the upward force exerted by the
floor of the elevator on a(n) 92 kg passenger?
Answer in units of N
Answer:
1012 N
Explanation:
There are two forces acting on the passenger.
Normal force N pushing up and weight force mg pulling down.
Apply Newton's Second Law:
∑F = ma
N − mg = ma
N − (92 kg) (9.8 m/s²) = (92 kg) (1.2 m/s²)
N = 1012 N

What is vaporization?Vaporization, conversion of a substance from the liquid or solid phase into the gaseous phase.
Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure.
When we are sweating:
Some of sweat has to evaporate off of your skin for this process to actually work. That's because cooling your body via sweating relies on a principle of physics called "heat of vaporization."
It takes energy to evaporate sweat off of your skin, and that energy is heat. As your excess body heat is used to convert beads of sweat into vapor, you start to cool down.
When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor.
As the sweat evaporates off your skin, you cool down.
Sweat is a great cooling system, but if you're sweating a lot on a hot day or after playing hard you could be losing too much water through your skin.
