Solve for the resultant displacement of the two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees

Answers

Answer 1

Answer:

The resultant of the vector is 6.63 km

Explanation:

Given;

vector A = 2.3 km 45°

vector B = 4.8 km 90°

The vectors in the x - direction is given by;

Aₓ = 2.3 km Cos 45° = 1.6263 km

Bₓ = 4.8 km Cos 90° = 0

The sum of the vectors in x -direction is given by;

∑X =  1.6263 km + 0 = 1.6263 km

The vectors in the y - direction is given by;

Ay = 2.3 km Sin 45 = 1.6263 km

By = 4.8 km Sin 90° = 4.8 km

The sum of the vectors in y -direction is given by;

∑Y =  1.6263 km + 4.8 km = 6.4263 km

The resultant vector is given by;

R = √(X² + Y²)

R = √[(1.6263)² + (6.4263)²]

R = 6.63 km

Therefore, the resultant of the vector is 6.63 km

Answer 2

The resultant displacement of the two vectors A and B is 6.63 Km and this can be determined by using the given data.

Given :

The two vectors: A = 2.3 km at 45 degrees B = 4.8 km at 90 degrees.

In order to determine the resultant displacement, first, determine the vector in x-direction:

\(\rm A_x=2.3cos45=1.6263 \;Km\)

\(\rm B_x=4.8cos90=0 \;Km\)

Now, the sum of the vectors is given by:

\(\rm \sum X=1.6263+0=1.6263\;Km\)

In order to determine the resultant displacement, first, determine the vector in y-direction:

\(\rm A_y=2.3sin45=1.6263 \;Km\)

\(\rm B_y=4.8sin90=4.8 \;Km\)

Now, the sum of the vectors is given by:

\(\rm \sum Y = 1.6263+4.8=6.4263\)

Now, the resultant vector is given by:

\(\rm R = \sqrt{X^2+Y^2}\)

\(\rm R=\sqrt{(1.6263)^2+(6.4263)^2}\)

R = 6.63 Km

The resultant displacement of the two vectors A and B is 6.63 Km.

at equal pressure, less lp gas will flow through an orifice than natural gas.T/F?

Answers

At equal pressure, less lp(liquefied petroleum) gas will flow through an orifice than natural gas. False.

At equal pressure, LP (liquefied petroleum) gas will generally flow through an orifice more easily than natural gas. This is due to the differences in the physical properties of the two gases.

LP gas, such as propane or butane, is stored in a liquid state under pressure. When the pressure is released, it vaporizes and becomes a gas. As a result, LP gas has a higher energy content and a higher vapor pressure compared to natural gas.

On the other hand, natural gas primarily consists of methane and is typically supplied through pipelines. It is in a gaseous state at normal atmospheric conditions.

When an orifice or a restricted opening is present, the flow rate of gas is determined by several factors, including the pressure difference across the orifice, the size of the orifice, and the properties of the gas.

Given equal pressure conditions, LP gas will tend to flow more readily through an orifice compared to natural gas. This is because LP gas has a higher vapor pressure, which means it has a greater tendency to expand and fill the available space. The higher energy content of LP gas also contributes to its ability to flow more easily through the orifice.

Therefore, the statement that less LP gas will flow through an orifice than natural gas at equal pressure is false. LP gas is expected to flow more readily through the orifice compared to natural gas.

Assume all temperatures to be exact.
The single glass pane in a window has dimensions of 1.80 m by 1.30 m and is 3.20 mm thick.
How much heat will flow through the glass in 1.50 h if there is a temperature difference of 7 ∘C between the inner and outer surfaces? (Consider conduction only.)
Express answer in J.

Answers

The heat flow through the glass in 1.50 h is 20512.5 J, assuming conduction only.

What is  the heat flow through the glass?

The amount of heat flow through a material is given by the formula: Q = kAΔTt/d, where Q is the heat flow, k is the thermal conductivity, A is the area, ΔT is the temperature difference, t is the time, and d is the thickness.

In this case, the thermal conductivity of glass is about 0.8 W/(m∙K), the area is 1.80 m × 1.30 m = 2.34 m², the temperature difference is 7 °C, the time is 1.50 h, and the thickness is 3.20 mm = 0.0032 m.

Substituting these values into the formula, we get:

Q = (0.8 W/(m∙K)) × (2.34 m²) × (7 °C) × (1.50 h) / (0.0032 m)

Q = 20512.5 J

Therefore, the heat flow through the glass in 1.50 h is 20512.5 J.

To summarize, the amount of heat flowing through a glass pane can be calculated using the formula Q = kAΔTt/d, where k is the thermal conductivity, A is the area, ΔT is the temperature difference, t is the time, and d is the thickness.

Types of Spectra 5) Stars like our Sun have low-density, gaseous atmospheres surrounding their hot, dense cores. If you were looking at the spectra of light coming from the Sun (or any star), which of the three types of spectrum would be observed? Explain your reasoning.

Answers

The spectrum observed from the Sun (or any star) would exhibit an absorption spectrum. This is because the outer gaseous atmosphere of the star absorbs specific wavelengths of light, resulting in dark absorption lines in the spectrum.

In the cooler, lower-density outer atmosphere, where white light from the star travels, some atoms or molecules in the atmosphere absorb photons with particular energy. In the spectrum, these absorptions show up as black lines at specific wavelengths. The specific set of absorption lines that each element or molecule generates results in a distinctive pattern that can be used to identify the elements that are present in the star's atmosphere.

The absorption spectrum offers insightful data on the chemical make-up and physical characteristics of the star. Astronomers can ascertain the elements present, their abundances, and other characteristics like the temperature, pressure, and velocity of the star's atmosphere by examining the absorption lines.

List 3 properties of waves

Answers

Answer:

1.wavelength

Explanation:

2. Frequency

3.Speed

4.Amplitude

Answer:

Wave is the propagation of disturbance from one place to another in an organised manner. Waves can be mechanical waves or non-mechanical waves. Mechanical waves like sound waves, require a medium to propagate. While electromagnetic waves are non-mechanical waves that do not require a medium and can travel through a vacuum.

If the particles of the medium move in a direction perpendicular to the wave propagation then the waves are called transverse waves. Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation.

5 Important Properties of Waves

The main properties of waves are as follows –

Property 1:Amplitude

The maximum displacement of the wave from the mean position is called the amplitude of the wave. It is the maximum height from the centre line to the crest or the trough. The crest is the highest point of the wave and the trough is the lowest point of the wave. Amplitude is measured in metres.

Property 2: Frequency

The number of vibrations passing a fixed point in a given amount of time is called frequency. The unit of frequency is Hertz.

Property 3: Wavelength

Wavelength is the distance between two identical points (adjacent crests or troughs). It is measured in metres. Frequency and wavelength are inversely proportional to each other.

Property 4: Time Period

The time taken by a complete wave to pass through a particular point is called the time period. The time period is measured in seconds. The time period is the reciprocal of the frequency.

Property 5: Speed

For a wave, speed is the distance travelled by a particular point on the wave in the given interval of time. Speed is measured in metres per second.

what term describes the most reactive nonmetals that have seven valence electrons?

Answers

The term that describes the most reactive nonmetals with seven valence electrons is "halogens."

The halogens belong to Group 17 (Group VIIA) of the periodic table and include elements such as fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements have seven valence electrons, meaning they require only one additional electron to achieve a stable octet electron configuration. Due to their strong desire to gain an electron and achieve a stable state, halogens are highly reactive and tend to form compounds through electron transfer or sharing. They readily react with metals to form ionic compounds and with other nonmetals to form covalent compounds. Halogens are known for their distinctive properties, including their reactivity, high electronegativity, and ability to form compounds with a wide range of other elements.

Find the electric field, the polarization, and the bound charge densities, P. and op. What is the total bound charge on the surface? Where is the compensating negative bound charge located?

Answers

(P4.33) A dielectric cube of side a, centered at the origin, carries a "frozen- in" polarization" P = kr, where k is a constant.(a)The total bound charge is given by Q_b, and since it is proportional to a^3, the bound charges will add up to zero only if k = 0. Otherwise, there will be a non-zero net bound charge.(P4.35)The total bound charge on the surface is given by Q_b, which is equal to -2χ_e q.

Problem 4.33, we have a dielectric cube of side length a centered at the origin. The polarization is given as P = kr, where k is a constant.

To find the bound charges, we need to consider the divergence of the polarization. The bound charge density, ρ_b, is given by:

ρ_b = -∇ · P

In this case, since P = kr, we can calculate the divergence:

∇ · P = ∂(krx)/∂x + ∂(kry)/∂y + ∂(krz)/∂z

= k + k + k

= 3k

Therefore, the bound charge density is:

ρ_b = -3k

To check if the bound charges add up to zero, we need to integrate the bound charge density over the volume of the cube:

Q_b = ∫∫∫ ρ_b dV

Since the polarization is "frozen-in" and the cube is centered at the origin, we can integrate over the volume of the cube:

Q_b = ∫∫∫ (-3k) dV

= -3k ∫∫∫ dV

= -3k (Volume of the cube)

= -3k (a^3)

The total bound charge is given by Q_b, and since it is proportional to a^3, the bound charges will add up to zero only if k = 0. Otherwise, there will be a non-zero net bound charge.

Problem 4.35, we have a point charge q embedded at the center of a sphere with linear dielectric material of susceptibility χ_e and radius R.

To find the electric field, polarization, and bound charge densities, we can use Gauss's Law for dielectric materials. The electric field inside the dielectric sphere is given by:

E = q / (4πε_0 χ_e R^2) * r

where r is the radial distance from the center.

The polarization, P, is related to the electric field by:

P = χ_e ε_0 E

Substituting the expression for E, we get:

P = χ_e q / (4πR^2) * r

The bound charge density, ρ_b, is given by:

ρ_b = -∇ · P

Since P only has a radial component, the divergence simplifies to:

∇ · P = ∂(χ_e q / (4πR^2) * r)/∂r

= χ_e q / (2πR^2)

Therefore, the bound charge density is:

ρ_b = -χ_e q / (2πR^2)

To find the total bound charge on the surface of the sphere, we integrate the bound charge density over the surface area:

Q_b = ∫∫ ρ_b dA

Since the bound charge is on the surface, we can integrate over the surface area of the sphere:

Q_b = ∫∫ (-χ_e q / (2πR^2)) dA

= -χ_e q / (2πR^2) ∫∫ dA

= -χ_e q / (2πR^2) (Surface area of the sphere)

= -χ_e q / (2πR^2) (4πR^2)

= -2χ_e q

The total bound charge on the surface is given by Q_b, which is equal to -2χ_e q. The negative bound charge is located on the surface of the sphere, compensating for the positive charge at the center.

We need to know about the electric fields to solve this problem. The electric field produced by a single-point positive charge is a radial field, whose strength is given by the equation

E = k.Q/r²

where E is the electric field, Q is the charge and r is the radius.

From the question above, we know that

k = 9 x 10⁹ Nm²/C²

Q1 = -5μC = -5 x 10¯⁶ C

Q2 = 4μC = 4 x 10¯⁶ C

x = 21 cm = 0.21 m

from midpoint (r = 0.105 m)

The electric field directly outward from Q2 to Q1 so that the total electric field between the charges will be added up.

Etotal = E1 + E2

Etotal = k.Q1/r² + k.Q2/r²

Etotal = k/r² x (Q1 + Q2)

What are photons?

According to De Broglie's dual nature of matter, light behaves as both wave and particle. If the light has the particle nature, the light particles are called photons.

The energy of one photon is E = hc/λ

Where h is the Planck's constant and c be the speed of light.

given that  λ = 470 nm

h = 6.63 × 10⁻³⁴ J. s

c = 3 × 10⁸ m/s.

Then E =  ( 6.63 × 10⁻³⁴ J. s × 3 × 10⁸ m/s ) /  (470 × 10⁻⁹ m) = 4.23 × 10 ⁻¹⁹ J.

This is the energy of one photon. If the total energy is 2.50 J. The number of photons = 2.50 J / 4.23 × 10 ⁻¹⁹ J = 5.93 × 10¹⁸.
