Find the index of refraction for diamond if the speed of light in diamond is 1.24 x 10m/s
Use the proper FORMAT
Answer:
Given speed of light in diamond =1.24*10m/s
speed of light (c) =3*10^8m/s
refractive index of diamond =3*10^8/1.24*10=2.41*10^7m/s
If it took Mrs. Coleman 1.4 s to go from the 10 m mark to the 15 m mark, what was Mrs. Coleman's average speed?
Answer:
1m every 0.28 seconds
Explanation:
she travelled 5 m in 1.4 s, so divide it by itself, 1.4s divided by 5 m gets you 0.28s for 1m

How do we know when an object is in static or dynamic equilibrium?
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.The amount of matter in an object is mass or weight

Which of the following shows a balanced nuclear reaction?
Answer:
No. 2
Explanation:
The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

State the Law of Electric Charges in your own words.
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

Answer:
1.F = 256 N
2.a = 8 m/s/s
By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.
F = ma
256 N = m * 8 m/s/s
m = 256 N/8 m/s/s
m = 32 Kg
The mass of water in the kettle is 0.50 kg. The specific heat capacity of water is 4200 J/kg °C. The initial temperature of the water is 100 °C. Calculate the average power output from the water in the kettle to the surroundings in 2 hours
Answer:
1.27 Mega watt approx
Explanation:
Given data
Mass= 0.5kg
c= 4200 J/kg °C
T1= 100°C
Time = 2 hours >>>> 7200 seconds
From the given data the water is already at the boiling point
Hence if continuous heat is being added the latent heat of vapourization will result, the latent heat of vaporization is about 2,260 kJ/kg
Q= mL
Q= 0.5*2,260
Q = 1130kJ
Power= Energy * Time
Power= 1130* 1130
Power= 1.27mega watt approx

Answer:
The vibrations from sound waves cause our ears to send signals to our brains to create sound. The speed of sound waves will determine the sound's pitch, or how high or low something sounds. Sound waves are important because they allow us to hear important messages and emergency signals to protect ourselves.

What volume of silver metal will weigh exactly 2500.0 g. The density of silver is 10.5 g/cm³
Answer:
Explanation:
Density = mass/volume
132g/(48.9 cm³) = 2.7 g/cm³
(27 g)/(3 cm³) = 9 g/cm³
512 g/(65 cm³) = 7.9 g/cm³
1.2 kg/(3243 cm³) cm³ = 1200 g/(3243 cm³) = 0.37 g/cm³

why do you think people translate sound waves from compression waves to transverse waves ?
Answer:
Sound waves are translated into transverse waves to know the frequency, amplitude, wavelength etc of the waves.
Explanation:
They translate the sound waves to know the depth about that specific waves and translating it to transverse waves makes it easier.

The pressure due to the liquid on an object immersed in that liquid is 4500 Pa
The density of the liquid is 900 kg/m.
What is the depth of the object below the surface of the liquid ?
Answer:
The depth of the object below the surface of the liquid is 0.510 meters.
Explanation:
The hydrostatic pressure ([tex]P[/tex]), measured in pascals, experimented by the object is directly proportional to density of the fluid ([tex]\rho[/tex]), measured in kilograms per cubic meter, gravitational acceleration ([tex]g[/tex]), measured in meters per square second, and depth of the object ([tex]h[/tex]), measured in meters. That is:
[tex]P = \rho\cdot g \cdot h[/tex] (1)
If we know that [tex]P = 4500\,Pa[/tex], [tex]\rho = 900\,\frac{kg}{m^{3}}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the depth of the object is:
[tex]h = \frac{P}{\rho\cdot g}[/tex]
[tex]h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]h = 0.510\,m[/tex]
The depth of the object below the surface of the liquid is 0.510 meters.
The depth of the object below the liquid's surface will be
"0.510 m".
Pressure and DensityAccording to the question,
Object immersed, P = 4500 Pa
Density of liquid, ρ = 900 kg/m³
Acceleration due to gravity, g = 9.8 m/s²
We know the relation,
→ Hydrostatic pressure (P) = ρ.g.h
or,
Depth will be:
→ h = [tex]\frac{P}{\rho .g}[/tex]
By substituting the values,
= [tex]\frac{4500}{900\times 9.8}[/tex]
= [tex]\frac{4500}{8820}[/tex]
= 0.510 m
Thus the above answer is appropriate.

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
