Answer:

x = 16 [m]

Explanation:

This problem can be solved using the following equation of kinematics.

[tex]v_{f}=v_{o}+a*t[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity = 5 [m/s]

a = acceleration = 3 [m/s²]

t = time = 2 [s]

[tex]v_{f}=5+3*(2)\\v_{f}=11[m/s][/tex]

Now we can find the displacement using the following equation of kinematics.

Options are;

(a) the red beam

(b) the violet beam

(c) it is the same for both beams

(d) cannot answer this without knowing the light intensity

Answer:

A: Red Beam

Explanation:

The energy of a photon is given by the formula;

E = hc/λ

Where;

h is Planck's constant

c is speed of light

λ is wavelength

From online sources, wavelength of red light is greater than that of violet.

Thus, it means that the value of E for red light will be lesser than that of violet since the denominator under red light will be larger. Therefore, the beam of red light will have the greatest number of photons hitting the surface per second.

The Planck's equation and the definition of power allow you to find the result for which beam has the largest number of photons is:

The energy of a photon is given by the Planck's equation.

          E = h f

Where h is the Planck constant and f the frequency.

The speed of light is related to wavelength and frequency.

           c = λ f

           f = [tex]\frac{c}{\lambda }[/tex]

Let's  substitute

          E = [tex]\frac{hc}{\lambda}[/tex]  

Power is defined as energy per unit of time.

         P = W / t

         P t = W

The wavelength of red light, in the order of 700 nm, is greater than the wavelength of violet light, which is on the order of 400 nm, therefore the energy of a photon of red light is less than the energy of a photon of violet light.

            [tex]E_{red} < E_{violet}[/tex]

The total energy deposited is the number of photons times the energy of each photons.  

         W = [tex]#_{photons} \ E_o[/tex]  

They indicate that the power delivered by the two rays is the same.

        [tex]P_{red} = P_{violet}[/tex]

        #_ {red photons} [tex]E_{o \ red}[/tex]d = #_{photons violet}  [tex]E_{o \ violet}[/tex]  

        [tex]number_{red \ photons} = \frac{E_{violet}}{E_{red}} \ number _{violet \ photons}[/tex]

The amount of energy of the violet photons is greater than the amount of energy of the red photons.

         [tex]\frac{E_{violet}}{E_{red}} > 1[/tex]  

Consequently, to leave the same power, there must be more red photons than violet wavelength photons.

In conclusion, using Planck's equation and the definition of power, we can find the result for which beam has the greatest number of photons is:

Newton 2ns law state that external forces that exert on an object is proportional to the mass and the acceleration of an object

Formula : ΣF = ma

ask me if you're confused with my answer

Answer: The volume of the gas at the increased pressure will decrease to 3.72L.

Explanation:

Boyle's law states that the volume occupied by a fixed mass of gas is inversely proportional to the pressure, provided temperature is kept constant. That is,

PV=K

P1V1 =P2V2

P1= 201 kpa

V1 = 6.2L

P2= 335kpa

V2= ?

Making V2 the subject of formula,

V2= P1V1/P2

V2= 201× 6.2/335

V2= 1246.2/336

V2= 3.72L

Thus, the volume of the gas decreases as the pressure increases. Hope this helps, thanks

Answer:

The volume will be 3.72 L.

Explanation:

We can find the new volume by using the Ideal Gas Law:

[tex] PV = nRT [/tex]

Where:

P: is the pressure

V: is the volume

n: is the number of moles

R: is the gas constant

T: is the temperature

Initially, we have:

[tex]P_{1}V_{1} = nRT[/tex]   (1)

with V₁ = 6.2 L, P₁ = 201 kPa and nRT = constant

When the pressure is increased we have:

[tex] P_{2}V_{2} = nRT [/tex]   (2)

with V₂ =?, P₂ = 335 kPa and nRT = constant

By equating (1) and (2) we have:

[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]

[tex] V_{2} = \frac{P_{1}V_{1}}{P_{2}} = \frac{201 kPa*6.2 L}{335 kPa} = 3.72 L [/tex]

Therefore, the pressure is increased to 335 kPa the volume will be 3.72 L.

I hope it helps you!

Answer:

h = 14.98 [m]

Explanation:

We can calculate this height using the definition of potential energy, which tells us that this energy is equal to the product of mass by gravitational acceleration by height. In this way we can find the height, by means of the following equation:

[tex]E_{pot}=m*g*h[/tex]

where:

Epot = potential energy = 6615 [J]

m = mass = 45 [kg]

g = gravity acceleration = 9.81 [m/s²]

h = elevation [m]

[tex]6615 = 45*9.81*h\\h = 14.98 [m][/tex]

This question is incomplete, the question is asking which enzyme unwinds the DNA molecule during DNA replication.

The answer is DNA HELICASE

Explanation:

DNA replication is the process whereby DNA molecule (genetic material) is duplicated in the genome i.e. DNA makes an identical copy of itself. The process of DNA replication is carried out in a step by step manner with various enzymes functioning specifically throughout the process.

The first step is to unwind the double-stranded DNA molecule into two single strands. The two single strands serves a templates to synthesize another pairing strand to make two DNA molecules in total. The unwinding of the DNA strands is carried out by an enzyme called DNA helicase.

Explanation:

The expression for the centripetal acceleration for the vertical circle is [tex]a_c = \frac{T_1 + T_2 }{2m}[/tex].

In a vertical circular motion, the tension of the swing at the top of the circle is given as;

[tex]T_1 =m a_c_{top} - mg\\\\T_1 = ma_c - mg\\\\mg = ma_c - T_1[/tex]

The tension of the swing at the bottom of the circle is given as;

[tex]T_2 = ma_{bottom} + mg\\\\T_2 = ma_c + mg[/tex]

solve the two equations together;

[tex]T_2 =ma_c + ( ma_c -T_1)\\\\T_2 = ma_c + ma_c - T_1\\\\T_2 + T_1 = 2ma_c\\\\a_c = \frac{T_1 + T_2}{2m}[/tex]

Thus, the expression for the centripetal acceleration for the vertical circle is [tex]a_c = \frac{T_1 + T_2 }{2m}[/tex].
