The correct option is A. The appearance of the first dark spot on either side of the large central bright spot in single slit diffraction is because the path difference is equal to half the wavelength.
How does the first dark spot in single slit diffraction appear?In single slit diffraction, light waves passing through a narrow slit spread out and interfere with each other, resulting in a pattern of bright and dark regions on a screen or surface. This pattern is known as the diffraction pattern.
The first dark spot on either side of the central bright spot, called the first minimum, occurs when the path difference between the waves from the top and bottom edges of the slit is equal to half the wavelength of the light.
When the path difference is equal to half the wavelength, the waves interfere destructively, resulting in a dark spot. This happens because the crest of one wave coincides with the trough of the other wave, leading to cancellation of the amplitudes and thus a minimum intensity at that point.
Therefore, option A is correct because the appearance of the first dark spot is indeed due to the path difference being equal to half the wavelength.

A force of 10 N acts to the left and a force of 5 N acts to the right on an object of mass 1 kg. If its initial speed is zero , what is its velocity after 1 second ?
Answer: -5 m/s
Explanation:
First find the net force by summing up the forces:
-10N + 5N = -5N
Use Newton's Second Law of motion to solve for the acceleration:
F = ma
-5N = 1kg(a)
a = -5 m/s^2
Use the first kinematic equation to solve for the final velocity:
Vf = Vi + at
Vf = 0 + (-5)(1)
Vf = -5 m/s

can you suggest improvement that can be made towards the design of siphon so that the transfer of liquid is much higher.
Answer:
A siphon is a tube that makes use of the potential energy of fluid at an elevated level to transfer the fluid to a lower level, due to pressure differences between the inlet and the outlet points of the tube, such that the pressure at the outlet is higher than the pressure at the inlet
The pressure energy is converted into velocity (kinetic) energy, and therefore, in other to increase the flow rate through the tube of a siphon, with constant diameter, the level of the fluid in the container at the inlet (supply) of the siphon is raised higher than the level at the outlet receiving) container or the outlet point of the siphon tube
The larger the difference between the inlet and outlet levels, the faster the transfer of fluid by the siphon

okay, so what i have learned from my experiences with doing school on e.d.g.e.n.u.i.t.y (they won't let me say the website name on here lol) is that after you write an extended response, they show you a sample response as well as these checkboxes which show things they wanted you to have included in your answer. ideally they want you to select all of them, meaning that all of those elements were included in your answer. it's not a matter or right or wrong; none of those checkboxes contain a wrong answer. you just select the ones that apply to your answer, and you won't get penalized if you don't select all of the checkboxes. you don't even have to select any of them. there's been times where my answer has been not at all what it should've been and i just click done without checking any of those boxes because i did not include any of those elements in my response. as long as the box that you wrote your answer in is outlined in green (which yours is, and that means that the computer likes your answer), you will be fine.
i hope this makes sense! it's sort of hard to explain. if you have any questions, just comment and i'll try my best to explain better lol. have a great rest of your day! <3

A plane has a take off speed of 1 point
300 km/h. What is the
acceleration in m/s2 of the
plane if the plane started from
rest and took 45 seconds to
take off? *
Answer:
Acceleration = 1.85m/s²
Explanation:
Given the following data;
Final velocity = 300km/h to m/s = 300*1000/3600 = 83.33m/s
Time = 45 seconds
Since the plane started from rest, initial velocity is equal to 0m/s.
To find the acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Where,
a is acceleration measured in [tex]ms^{-2}[/tex]
v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = (83.33 - 0)/45
Acceleration = 83.33/45
Acceleration = 1.85m/s²
Therefore, the acceleration of the plane is 1.85m/s².

Given the following situation of marble in motion on rolling 10 m/s horizontally from a height of 1.5-m with negligible friction.
a.) Once the ball leaves the table, calculate how long it will take for the ball to hit the floor?
b.) How far will the ball travel horizontally before hitting the floor?
Answer:
The ball would hit the floor approximately [tex]0.55\; \rm s[/tex] after leaving the table.
The ball would travel approximately [tex]5.5\; \rm m[/tex] horizontally after leaving the table.
(Assumption: [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)
Explanation:
Let [tex]\Delta h[/tex] denote the change to the height of the ball. Let [tex]t[/tex] denote the time (in seconds) it took for the ball to hit the floor after leaving the table. Let [tex]v_0(\text{vertical})[/tex] denote the initial vertical velocity of this ball.
If the air resistance on this ball is indeed negligible:[tex]\displaystyle \Delta h = -\frac{1}{2}\, g\, t^{2} + v_0(\text{vertical}) \cdot t[/tex].
The ball was initially travelling horizontally. In other words, before leaving the table, the vertical velocity of the ball was [tex]v_0(\text{vertical}) = 0 \; \rm m \cdot s^{-1}[/tex].
The height of the table was [tex]1.5\; \rm m[/tex]. Therefore, after hitting the floor, the ball would be [tex]1.5\; \rm m \![/tex] below where it was before leaving the table. Hence, [tex]\Delta h = -1.5\;\rm m[/tex].
The equation becomes:
[tex]\displaystyle -1.5 = -\frac{9.81}{2} \, t^{2}[/tex].
Solve for [tex]t[/tex]:
[tex]\displaystyle t = \sqrt{1.5 \times \frac{2}{9.81}} \approx 0.55[/tex].
In other words, it would take approximately [tex]0.55\; \rm s[/tex] for the ball to hit the floor after leaving the table.
Since the air resistance on the ball is negligible, the horizontal velocity of this ball would be constant (at [tex]v(\text{horizontal}) =10\; \rm m \cdot s^{-1}[/tex]) until the ball hits the floor.
The ball was in the air for approximately [tex]t = 0.55\; \rm s[/tex] and would have travelled approximately [tex]v(\text{horizontal})\cdot t \approx 5.5\;\rm m[/tex] horizontally during the flight.

How does the composition of a comet compare with that of the Sun?
Both objects are composed of gas.
Both objects contain a form of water.
Comets are made of ice and dust, while the Sun is made of gas.
Comets are made of frozen rock, while the Sun is made of burning rock.
Answer:
C
Explanation:
The composition of a comet compared with that of the Sun is C "Comets are made of ice and dust, while the Sun is made of gas".
What are comets?Comets are small, icy bodies that originate from the outer solar system and are composed mainly of frozen water, carbon dioxide, methane, and ammonia, along with dust and small rocky particles. When a comet approaches the Sun, its icy material vaporizes, creating a glowing coma (a hazy atmosphere around the nucleus) and a tail that points away from the Sun due to the solar wind.
On the other hand, the Sun is a giant ball of hot, glowing gas, composed mainly of hydrogen (about 73% of its mass) and helium (about 25% of its mass), with trace amounts of other elements like oxygen, carbon, and iron. The Sun generates energy through nuclear fusion reactions in its core, which convert hydrogen into helium and release a tremendous amount of energy in the process.
Therefore, the composition of a comet is quite different from that of the Sun. While both objects contain some water (in the form of ice for comets and vapor for the Sun), comets are predominantly made of ice and dust, while the Sun is predominantly made of gas, with only a small amount of solid material in its core.

A rocket at rest with a mass of 942 kg is acted on by an average net force of 6,731 N upwards for 21 s. What is the final velocity of the rocket?
Answer:
Final velocity, V = 150.15 m/s
Explanation:
Given the following data;
Mass = 942kg
Net force = 6,731N
Time = 21secs
To find the final velocity of the rocket;
First of all, we would determine the acceleration of the rocket with respect to time.
Force = mass * acceleration
Substituting into the equation, we have;
6,731 = 942*acceleration
Acceleration = 6731/942
Acceleration = 7.15m/s²
Now, to find the final velocity we would use the first equation of motion.
V = U + at
Since the rocket started from rest, its initial velocity (U) is zero.
V = 0 + 7.15*21
Final velocity, V = 150.15 m/s

1- A positive charge of 3x10-7 is located in a field of 27N/C directed toward the south. What is the force acting on the charge?
2- A positive test charge of 5x10-6Cis in an electric field that exerts a force of 2x10-4N on it.
What is the magnitude of the electric field at the location of the test charge?
Explanation:
(1) Given that,
A charge, [tex]q=3\times 10^{-7}\ C[/tex]
Electric field, E = 27 N/C
We need to find the force acting on the charge. The force on the charge is given by :
[tex]F=qE\\\\F=3\times 10^{-7}\times 27\\F=8.1\times 10^{-6}\ N[/tex]
So, the force acting on the charge is [tex]8.1\times 10^{-6}\ N[/tex]
(b) Charge, [tex]q=5\times 10^{-6}\ C[/tex]
Force, [tex]F=2\times 10^{-4}\ N[/tex]
Let E be the electric field.
[tex]E=\dfrac{F}{q}\\\\E=\dfrac{2\times 10^{-4}}{5\times 10^{-6}}\\\\E=40\ N/C[/tex]
So, the electric field is 40 N/C.
