Answer:
cation, anion
Explanation:
Binary Ionic Compounds- Binary means 2, ionic relates to charges. Therefore binary ionic compounds have TWO elements, with charges that cancel eachother out. The cation (or positive charge) goes before the anion (or negative charge)
example:
NaCl
Na^+1
Cl^-1
Sodium Chloride

Science question!! Please help
Answer:
It lasted two hours or 120 minutes, it would be smart to say that he was riding up it during the interval 20-60min and riding down it during the interval 60-80min. This is an assumption made because of his speed, when going up a hill our speed is slower while when riding down it, you gain a lot of speed.
In terms of forces, what makes the arrow start moving?
Answer:
the answer is A force is a push or pull that changes the motion of an object. Forces can make objects start or stop moving, cause objects that are already moving to speed up or slow down, or make objects change direction. Force arrows are used to represent both the magnitude and direction of forces.

Can someone please answer these two science questions. Please don't answer with just anything for the points, I genuinely need the answers. Thanks! :)
6.
Answer:
45 meters
Explanation:
notice that is you multiply the time with the speed the units cancel to get distance.
therefore
distance=velocity(time)
distance=(3)15
distance =45 meters
7.
Answer:
1. the speed is constant
2. the average speed is .5 m/s
Explanation:
I have attached a graph of the data in excel.
from excel i got the equation of the line to be y=.5x with y being distance and x being time.
the function is a position function so if you take the derivative of it you get the velocity which is .5.
since the derivative is a constant the the speed does not change and the average velocity is the derivative.

An electric field around two charged objects is shown.
Two spheres next to each other. Vectors perpendicular to each surface spread out and go to the other charge. The vectors are from the charge on the left, labeled X, and to the other charge, labeled Y. The vectors on the opposite sides of the charges are not bent.
What are the charges of objects X and Y?
Answer: D
X: positive
Y: negative
Explanation:
It's either A or D and I chose A and got it wrong.
Answer:
D) Y and Z are opposite charges, but their identities cannot be determined.

The force of the collisions of gas particles with other particles
of matter is known as
Answer:
Kinetic molecular
Explanation:
discharge occurs when oppositely charged objects get close enough for the air between them to become electrically charged.
Answer:
It does both. Once they get close enough the air does start to get charged, but then they eventually discharge when they touch.

Magnetic fields go from the north poles of magnets to the south poles of magnets.
true or false
The Answer is true, the saying opposites attract are true for magnets when poles match though they repel.
Answer:
true
Explanation:
A charged particle is placed in a space. The particle experiences a force. What can be concluded?
A.
The space contains a magnetic field.
B.
The space contains an electric field.
C.
The space has a charge opposite to the particle's.
D.
Oppositely charged particles must be present.
Answer: A.
The space contains a magnetic field
Explanation:
A charged particle is surrounded by electric field and exerts force on other charges in the field, attracting or repelling them.
But a charged particles in a magnetic field can escape into infinity without ever stopping due to magnetic force. We can therefore conclude that the space contains a magnetic field

1. What are three things you think of when you think of energy?
Answer:
Food, wind, water.
Explanation:
This is supposed to be a personalized question so I answered with things that can make/give energy.
Answer:
This is personal question, very interesting! Depend on who is the person, where the person is working at, how old is that person - we can have various answers.
Personally, I think first about that human and other animals needs energy to survive, that means we need to eat, to drink; The plants need energy to survive too - that is the energy from the Sun.
Secondly, the human being needs such types of energy as electricity, wind, solar energy, etc. in oder to live. Even the acient people learnt to use solar and wind and water - natural energy from the nature.
Thirdly, the human being needs spiritual energy to have a good life.
Another specific terms of energy related to physics and chemistry, and even biology - actually are not in my mind in everyday life.

How much voltage must be applied across a 0.20 Ω wire in order to create a 30 A current? (Please show work for it too)
Answer:
6 V
Explanation:
By ohm's law :
V = IR
V = 0.2 × 30 = 6 V
Answer:
V=6V
Explanation:
Use the equation I=V/R and solve for V then use V=IR plug in the numbers.
V=IR
V=30(0.2)
V=6V

If the frequency of wave is 400 Hz and its
wavelength is 2.5 m, what is the velocity?
a 3000 km/s
b 100 m/s
C 10000 m/s
d 1000 m/s
Answer:
D) 1000 m/s
Explanation:
[tex]wavelength = \frac{velocity}{frequency}[/tex]
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.

For any energy source including batteries, there will be conduction of electricity if there is a potential
difference
similarity
Answer:
Difference
Explanation:
The electricity conduction happens when there is a flow of current. The flow of current from one point to another can only occur if there is a potential difference.
If there is not potential difference between two points the current will not flow and thus electricity conduction will also be not possible. The current in the circuit will flow from higher potential point to lower potential point.
