Answer: The potential difference between the plates = 0.4061V
Explanation:
Given that the
Electric field strength E = 155 N/C
Distance d = 0.00262 m
From the definition of electric field strength, is the ratio of potential difference V to the distance between the plates. That is
E = V/d
Substitute E and d into the above formula
155 = V/0.00262
Cross multiply
V = 155 × 0.00262
V = 0.4061 V
The potential difference between the plates is 0.4061 V

The diagram represents two small, charged, identical metal spheres, A and B, that are separated by a distance of 2.0 meters. If the two spheres were touched together and then separated, the charge on sphere A would be *
q1= -1.6x10^-6C
q2=+1.0x10^-6 C
d=2m
Final answer is -3.0x10^-7 C, but I don't know why it is like that.
Answer:
if you are trying to figure out if it is right. I believe it is right (the answer) but trust your instincts go for it.
Explanation:
The charge on sphere A is -3 × 10⁻⁷C.
Distribution of charge:According to the question, there are two identical spheres, sphere A and sphere B with charges
q₁= -1.6 × 10⁻⁶C , and
q₂=+1.0 × 10⁻⁶ C respectively separated by a distance of 2m.
Now, the charges are brought in contact with each other. So the total charge on both the spheres when they are in contact would be the sum of the two charges, that is:
q = q₁ + q₂
q = -1.6 × 10⁻⁶C + 1.0 × 10⁻⁶ C
q = -0.6 × 10⁻⁶C, or
q = -6 × 10⁻⁷C
Since the two spheres are identical, when they are separated from each other, the charge is distributed equally on both of them. So, the charge on each sphere is :
Q = q/2
Q = (-6 × 10⁻⁷C)/2
Q = -3 × 10⁻⁷C

A girl on the beach sees 8 waves pass in 4 s. If the wavelength of each
wave 1.2 m, what is the velocity of the waves?
This is for cherylnotcherry
Velocity = frequency x wavelength
= [tex]\frac{8}{4}[/tex] x 1.2
= 0.6 m/s
Answer:
The velocity of wave is 2.4m/s.
Explanation:
First, find the frequency using the formula :
[tex]f = \frac{1}{t} [/tex]
Let t = 4,
[tex]f = \frac{1}{4} [/tex]
[tex]f = 0.25Hz[/tex]
Next, given that each wave is 1.2m and there are 8 waves so the wavelength is :
[tex]λ = 1.2 \times 8[/tex]
[tex]λ = 9.6m[/tex]
Lastly, you have to use velocity formula :
[tex]v = f \times λ \: [/tex]
Let f = 0.25Hz,
Let λ = 9.6m,
[tex]v = 0.25 \times 9.6[/tex]

Jaipal measures a circuit at 1.2 A and 24 . Using Ohm’s law, what can he calculate for the circuit? current (C) current (I) voltage (V) voltage (A)
Answer: voltage (V)
Explanation:
Hi, in the answer the letter A (1.2 A) stands for Ampere, and the symbol next to the number 24 must be Ω 8 (Ohms)
So, applying Ohm's law:
Voltage (V) =current (I) x resistance (R)
V = I x R
Replacing with the values given;
V = 1.2 A x 24Ω
In conclusion, we can calculate the value of Voltage for the circuit.

What is the mass of an object that has a density of 3.2 g/cm3 and a volume
of 5.5 cm3? (The density of an object has the equation d =m/v.)
Answer:
The mass of an object is 17.6 grams.
Explanation:
We have,
Density of the object is 3.2 g/cm³.
Volume of the object is 5.5 cm³
It is required to find the mass of the object. The density of the object is given by the mass acting per unit its volume. It is given by :
[tex]\rho =\dfrac{m}{V}[/tex]
m is the mass of an object
[tex]m=\rho \times V\\\\m=3.2\ g/cm^3 \times 5.5\ cm^3\\\\m=17.6\ g[/tex]
So, the mass of an object is 17.6 grams.

If gravity is the only force present, what is the total mechanical energy of a
rock falling off a cliff at a time when its potential energy is 500 J and its
kinetic energy is 600 J?
A. 500 J
B. 100 J
C. 600 J
D. 1,100 J
Answer:
(D) is correct option.
Explanation:
At a particular time, the potential energy of a rock is 500 J and its kinetic energy is 600 J.
It is required to find the mechanical energy of the rock. Mechanical or total energy is the sum of kinetic and potential energy. So,
TE = K+ P
TE = 500 J + 600 J
TE = 1100 J
So, the total mechanical energy of a rock is 1100 J. Hence, the correct option is (D).
Answer:
1,100

What is the difference between a neutral atom and an ion?
Answer:
a neutral atom has no charge, while an ion does.
Explanation:
cation = positive charge
anion = negative charge
A neutral atom has no charge while an ion has charge which depends on whether it looses or gains electrons.
What is an ion?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.They are produced in the solid or liquid state in the presence of salts when they react with solvents.

the concentration of potassium ions in solution
how acidic a solution is
the concentration of hydrogen ions in solution
Answer:
here is your answer..
Explanation:
the concentration of hydrogen ions in solution
Hydrogen ion concentration in a solution is called pH so, option 'D' is the correct answer.
What is pH ?The concentration of hydrogen ions in a solution is measured by its pH, which is a measure of its acidity. Pure water splits into hydrogen and hydroxyl (OH-) ions in roughly equal amounts.
The word pH denotes the concentration of hydrogen ions in a solution, such as what percentage of a solution contains hydrogen ions. The pH scale ranges from 1 to 14, with 1 being the most acidic and 14 being the most alkaline.

A 800 kg car is traveling a 4.5 m/s. What is the momentum of the truck?
Answer:
3600 kg m/s
Explanation:
Momentum can be calculate using the following formula:
p=m*v
where p is the momentum in kg m/s, m is the mass in kilograms, and v is the velocity in m/s.
We know the mass of the car is 800 kilograms and the car is traveling at 4.5 m/s. So, m=800 and v=4.5 Therefore, we can substitute 800 for m and 4.5 for v.
p=m*v
p=800*4.5
Multiply
p=3600
The momentum is 3600 kg m/s
If the average speed of a drag racing car is 0.069 miles second, how long would it take the car to complete a 1/4 mile (0.25 mile) straight track?
Answer: 3.6 seconds
Explanation:
The correct speed of the car is 0.069 miles per second.
Hi, to answer this question we have to apply the next formula:
Time = distance / speed rate
Replacing with the values given:
t = 0.25 m/ 0.069 mps =3.6 seconds
It would take the drag racing car 3.6 seconds to complete a ¼ mile straight track.

You and your lab partner, Mel, are engrossed in a chemistry activity using beans to compute the average atomic mass of an element "beanium". You have three isotopes of beanium to measure. Using a triple beam balance, you find the mass of each isotope three times and then take an average. You and Mel compute an average mass for beanium of 8.93 grams and your percent error is 18%. Your teacher instructs you to try again and you end up with the same results. In fact, no matter how many times you try, your percent error is between 18 - 20%.
What is the MOST LIKELY source of error in this activity?
A) random error: Mel misreads the balance occassionally.
B) random error: You and Mel take turns reading the balance and do not read it to the same accuracy.
