Carbon emits photons at 745 nm when exposed to blackbody radiation. How much energy would be obtained if 44g of carbon were irradiated? Assume each carbon atom emits one photon.

Its final volume be 1.76 Liters. The term "Final Volume" refers to the amount of Water Allocation (expressed as a whole number of Megaliters) that was determined in line with section 3.3 and was included in an Offer.

An experimental gas law known as Avogadro's law or Avogadro-hypothesis Ampère's connects the volume of a gas to the amount of gas material present. The law is an instance of the ideal gas theory. With the aid of the following formula, one may determine how much more space a gas takes up when its quantity is increased: V1/n1 = V2/n2 (= k, according to Avogadro's law).

Given the following data:

To find the final volume of the gas, we would apply Avogadro's Law:

Avogadro's Law is provided by the formula:

v/n=7

[tex]v_{1} /n_{1}[/tex] = [tex]v_{2} /n_{2}[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]2.46/0.158=v_{2}/0.113[/tex]

[tex]2.46*0.113=0.158v_{2[/tex]

0.27798=[tex]0.158 v_{2[/tex]

[tex]v_{2[/tex]= 0.27798/0.158

Hence, Final volume = 1.76 Liters.

A caiman swims 190 meters at a speed of 10 m/s and it then enters a stream and slows to 2 m/s for 270 meters and then the average speed of this cousin of the crocodile is 2.98 m/s.

The overall distance the object covers in a given amount of time is its average speed.

A scalar value represents the average speed thus it means that it has no direction and is thus by the magnitude.

The distance travelled is divided by the time taken and it is the formula for calculating average speed.

The alternative formula is to add into the initial and final speeds altogether and divide by two if you have the values.

The entire distance travelled is then divided by the total time interval to determine the average speed.

d1 = 190m

d2 = 270m

v1 = 10m/s

v2 = 2m/s

average speed = total distance/total time

t1 = 190/10 = 19s

t2 = 270/2 = 135s

so average speed = (190+270)/ (19+135)

= 460/154

1. The speed of the source is 34m/s, using Doppler effect.

4. Tthe distance the source has fallen in time ([tex]t_{1} + t_{2}[/tex]) is 65m.

A wave's frequency changes in response to an observer moving in respect to the wave source, which is known as the Doppler effect or Doppler shift. It has the name of Christian Doppler, an Austrian physicist who first reported the phenomena in 1842.

Mathematically it is written as;

[tex]f' = \frac{(v+v_{0}) }{(v -v_{s}) } f[/tex]

1. Using doppler effect,

u = 340(440/440-1) m/s

u = 34m/s

Therefore, the speed of the source is 34m/s.

2. y = [tex]u^{2}[/tex]/2g

y = [tex]34^{2}[/tex]/2×9.8

y = 58.92m

So, [tex]t_{1}[/tex] = u/g       (Using u obtained above from Doppler effect)

[tex]t_{1}[/tex] = 34/9.8

[tex]t_{1}[/tex] = 3.466s

Therefore, the location of the source at that time ([tex]t_{1}[/tex]) is 3.466s.

3. [tex]t_{2}[/tex] = 58.92 / 340

[tex]t_{2}[/tex] = 0.173s.

Therefore, the time ([tex]t_{2}[/tex]) for sound to travel 58.92 m is 0.173s.

4. d = [tex]\frac{1}{2}gt^{2}[/tex]

d = [tex]\frac{(9.81)(3.639^{2}) }{2}[/tex]

d = 65m.

Therefore,  the distance the source has fallen in time ([tex]t_{1} + t_{2}[/tex]) is 65m.

The frequency ()of photons to break the O-H bond is 1.1704 ✕ 1015 Hz.

Here, it is given that

The bond energy of O-H per mole=E =467 kJ/mol

Convert the unit of bond energy from kJ to J by using a conversion factor:

1kJ =1000 J

467 kJ/mol = 467 ✕ 103 J /mol

Determine the bond energy for 1 molecule of water (H2O) as:

E = Bond energy per mole / Avogadro’s number (NA)

E = (467 ✕ 103 ) / (6.022 ✕ 1023 )

=  77.55 ✕ 10-20 J

Thereby, the energy required to break 1 molecule of H2O is 77.55 ✕ 10-20 J

Now, determine the frequency in Hz by using a relation:

E=h

Where ‘’ is the frequency of the photon and ‘h’ is the Planck’s constant whose value is 6.626  ✕ 10-34 J/s.

Putting all the values we get,

(77.55 ✕ 10-20 J) = (6.626  ✕ 10-34 J/s) ✕

= (77.55 ✕ 10-20 J) / (6.626  ✕ 10-34 J/s)

= 11.704  ✕ 1014 s-1

= 1.1704 ✕ 1015 s-1

Both the ships will see the other ship with the same velocity i.e, 0.999c m/s.

To calculate the velocity of one ship as seen by the other ship, we need to use the velocity transformation formula derived from Lorentz transformation:

Here v1 and v2 are the velocities of the two ships

As the ships are heading towards each other v1 = -v2 = 0.999c

Putting this value in the above equation

V = 0.999c + 0.999c/1 - (0.999c)(0.999c) x c = 0.999c m/s

(a) Let us say, the mass of the girl to be M.

The height of the window is 12m.

When the girl jumps out of the window it becomes a case of free fall so we can apply the equations of motion because downward acceleration as constant. The initial velocity U of the girl is zero.

The final velocity of the girl on reaching the ground is V.

V = √2gH

V = √2x9.8x12

V = √235.2

V = 15.33 m/s.

Change in momentum (Δp) = M(V-U)

Δp = 48(15.33-0)

Δp = 736.32 Kg-m/s (Downwards).

(b) The impulse on the net will be equal to the change in momentum of the girl i.e. 736.32 Kg-m/s, because the net was initially at rest and the final velocity of the net is same as that of the girl. Impulse is nothing but change in momentum.
