Answer:

Sulfur trioxide is a colourless compound that exists at room temperature either as a volatile liquid or in any of three allotropic solid forms. What is SO2 and SO3? SO2 is sulfur dioxide which is a gaseous compound formed from sulfur and oxygen atoms. The melting point and the boiling point are -71℃ and -10℃respectively.

Explanation:

Answer:

0° C = 273.15 K

0 K = - 273.15° C

Explanation:

Hello there!

The Kelvin temperature scale refers to the absolute temperature scale. The division in the Kelvin scale is equal to a degree on the Celsius scale only it's difference is zero

The Celsius scale of zero (0°C) is the freezing point.

0 K is Absolute Zero.

•°• 0 K = - 273.15° C

0° C = 273.15 K

Furthermore, this is what I would like you to know about this scales;

The Kelvin scale is used for very low or very high temperatures where water is not involved.

Note:

The boiling point of water is 100°C.

I hope this helps you to understand more on this scales. Have a nice studies.

Positioning your Slinky along any direction different from its initial position will affect your reading, because there will be change in the magnetic field.

If the Slinky is made of an iron alloy, it can be magnetized by itself. Moving the Slinky around can cause a change in the magnetic field, even if no current is flowing.

When there is a change in the magnetic field, the reading changes.

At any point, you change the orientation of the Slinky, you will need to zero the reading or adjust the Slinky back to its initial position, even if the sensor does not move.

Thus, Positioning your Slinky along any direction that is different to its initial position will affect your reading because there will be change in the magnetic field.

Answer:

the doppler effect shows stars with red shifted light

Explanation:

light from a receding star is shifted toward red or redshifted

redshift is an example of the doppler effect

the wavelength of the light is stretched so the light is seen as shifted towards the red part of the spectrum

Answer:

A prism can disperse light into different colors when the light enters the prism at a "fixed" angle - light coming in, perhaps, thru a narrow slit

If light can enter at all angles, then dispersion occurs at all angles and no dispersion can be seen

Answer:

420J

Explanation:

The formula (useful output ÷ total output) × 100 is used. We need to find the the useful output. So:

(useful ÷ 600) × 100 = 70(%)

We rearrange the formula so that 'useful' is the subject of the equation.

useful ÷ 600 = 0.7 {70 ÷ 100}

useful = 0.7 × 600

useful = 420J

Use the right equation. To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos (x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.

There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

The current in the circuit is determined by applying Ohms law as shown below;

V = IR

where;

I = V/R

At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.

Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.

Answer:

Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes

Explanation:

Explanation:

Initial velocity ( u ) = 10 m/s

Final velocity ( v ) = 40 m/s

Time taken ( t ) = 15 second

Now

[tex]acceleration = \frac{v - u}{t} \\ = \frac{40 - 10}{15} \\ = 2m /{s}^{2} [/tex]

We can use the "suvat" method

s is displacement

u is initial velocity

v is final velocity

a is acceleration

t is time

We substitute in what we know...

s = ?

u = 22.5 (the speed/velocity the trucks is initially)

v = 0 (the truck comes to a stop)

a = -2.27 (negative because it is decelerating

t = ?

[tex]\text{suvat formulae}:\\v = u + at\\s = ut + \frac{1}{2}at^2\\v^2 = u^2 + 2as\\s = \frac{v+u}{2}t\\s = vt - \frac{1}{2}at^2[/tex]

We have [tex]u[/tex], [tex]v[/tex], [tex]a[/tex] and we want to find the time for how long it takes the truck to stop.

We can use [tex]v = u + at[/tex]

[tex]v = u + at\\0 = 22.5 - 2.27 \times t\\\frac{-22.5}{-2.27} = t\\t = 9.91...\ \text{s}[/tex]

To find the distance (displacement), we can use [tex]s = ut + \frac{1}{2}at^2[/tex]

[tex]s = ut + \frac{1}{2}at^2\\s = 22.5 + \frac{1}{2} \times -2.27 \times 9.91^2\\s = -88.9661935\ \ \text{(we make it positive since you can't have negative distance)}\\s = 88.97...\ \text{m}[/tex]

To find the distance travelled 3 seconds after breaks are applied;

We just use the same formula, but with [tex]t = 3[/tex]

[tex]s = ut + \frac{1}{2}at^2\\s = 22.5 \times 3 + \frac{1}{2} \times -2.27 \times 3^2\\s = 12.285\ \text{m}[/tex]

Answer:

It has a mass of 40 kg.

Explanation:

Because Force = mass x Acceleration or F = m a, we could say that the mass is force/acceleration which in your case is 2,400/60 which equals 40 kg.

Answer:

The answer will be it has a mass of 40 kg.

Explanation:

Because Force = mass x acceleration or F = m a, we can say Force divided by mass or F/a = m or mass so 600 divided by 15 equals 40 kg.

T = 2π√(L/g)

For earth , g ~ 10

18.9 = 2×3.14 √(L/g)

9 = L/g

L = 90 metres

Answer:

88m

Explanation:

T=2π*[tex]\sqrt{L/g}[/tex]-->Τ/2π=[tex]\sqrt{L/g}[/tex]-->18.9/2π=[tex]\sqrt{L/g}[/tex]-->3=[tex]\sqrt{L/g}[/tex]-->3^2=L/g-->9=L/9.8

so L=9*9.8-->L≈88m

The distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º will be 0.0000034 m.

A diffraction grating is a type of optical instrument obtained with a continuous pattern. The pattern of the diffracted light by a grating depends on the structure and number of elements present.

The distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º is;

The equation of diffraction grating is given as;

[tex]\rm d sin \theta = n \lambda \\\\ dsin60=2 \times 760 \times 10^{-9} \\\\ d=0.00000304 \ m[/tex]
