Answer:

Percentage of mass converted to energy = 99.9 %

Explanation:

By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star. Seen from afar (on the scale of distances between stars) the presence of the solar system would not be obvious. We would simply see a normal-looking star. Perhaps we would pick up the presence of Jupiter, which makes up two thirds or so of the solar system outside of the Sun, by mass.

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".

According 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.

Explanation:

The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.

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.

[tex]\boxed {\boxed {\sf 133,500 \ Joules}}[/tex]

Explanation:

Since we are given the specific heat, mass, and change in temperature, we should use this formula for heat energy.

[tex]q=mc \Delta T[/tex]

The mass is 2 kilograms. Iron's specific heat is 445 Joules per kilogram degree Celsius. The temperature increases by 150 degrees Celsius.

[tex]m= 2 \ kg \\c= 445 \ J/kg \textdegree C\\\Delta T= 150 \textdegree C[/tex]

Substitute the values into the formula.

[tex]q= (2 \ kg)( 445 \ J/kg \textdegree C)(150 \textdegree C)[/tex]

Multiply the first two numbers. The kilograms will cancel.

[tex]q= 890 \ J/\textdegree C (150 \textdegree C)[/tex]

Multiply again. This time the degrees Celsius cancel.

[tex]q= 133, 500 \ J[/tex]

The pan absorbs 133,500 Joules of heat energy.

Answer:

Total resistance is 96 ohm

Explanation:

Rs = R1 +R2 + R3 + R4 + R5 +R6 + R7 + R8

where R1 is lamp 1

R2 is lamp 2 n so on

Rs = 12 + 12 +12 + 12 +12 + 12 + 12 + 12( as each lamp is of resistance 12)

Rs = 96 ohm

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

Explanation:

The diagram which correctly represents the temperature of the two substances and the direction of heat flow is shown below.

Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from one physical object to another, especially as a result of a difference in temperature.

During the process of heat conduction, heat is primarily transferred between objects with different degrees of temperature and materials that are directly in contact with each other.

In conclusion, heat is generally transferred from a hotter object (37°C represented by the orange circles) to a cooler object (0°C represented by the blue circles) as shown in the image attached below.

Answer:

11.3 g/cm^3

Explanation:

density = mass/volume

volume of rectangular prism = length * width * height

volume = (4.50 cm)(5.20 cm)(6.00 cm) = 140.4 cm^3

mass = 1587 g

density = (1587 g)/(140.4 cm^3)

density = 11.3 g/cm^3

Explanation:

According to the given diagram, the c identifies the wavelength of the curve. Hence, option C is correct.

In order to characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10-9 nanometers (nm) or angstroms (10-10 m) are more usually used.

The relationship between frequency and wavelength is inverse, with frequency being the number of wave cycles per second. A signal's wavelength shortens as its frequency rises, or we may say that the relationship between wavelength and refractive index is inverse.
