If two monochromatic light waves undergo destructive interference, the amplitude of the resultant wave is
Answer: The amplitude is 0. (assuming that the amplitude ot both initial waves is the same)
Explanation:
When two monochromatic light waves of the same wavelength and same amplitude undergo destructive interference, means that the peak of one of the waves coincides with the trough of the other, so the waves "cancel" each other in that point in space.
Then if two light waves undergo destructive interference, the amplitude of the resultant wave in that particular point is 0.
Answer:
No, the resulting wave in the diagram does not demonstrate destructive interference. The resulting wave in the diagram shows a bigger wave than Wave 1 or Wave 2. If it demonstrated destructive interference, it would be a smaller wave or a horizontal line. With destructive interference, waves break down to form a smaller wave, or cancel each other out, resulting in no wave formation.

Q: You're playing a game of catch with a dog, the dog is initially standing near your feet. Then he jogs 20ft in a straight line to retrieve the stick and carries the stick 15ft back towards you before lying on the ground to chew the stick.
A). Cal the total distance
B) . Total displacement
C). Show that the net displacement of the trip is the sum of the sequential displacement that makes up the trip.
Answer:
A) 35 ft
B) 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick
Explanation:
A) Total distance covered by the dog = 20 + 15
= 35 ft
B) Since the other distance covered by the dog before chewing the stick, after the retrieval, was in an opposite direction to the initial direction, then;
total displacement of the dog = 20 - 15
= 5 ft
C) Net displacement = distance covered by the dog to retrieve the stick + distance covered before the dog starts chewing the stick
But, displacement involves a specified direction. The distance covered before the dog starts chewing the stick was in an opposite direction to the initial direction.
Thus,
Net displacement = distance covered by the dog to retrieve the stick - distance covered before the dog starts chewing the stick

Q11) If you were standing at the top of a building and you dropped a rock.
you noticed that the rock took 5.2 s to hit the ground. Find the total
distance the rock traveled and the speed when the rock hit the ground.
Answer:
Part A
The distance travel by the rock is approximately 132.496 m
Part B
The speed when the rock hits the ground is approximately 50.96 m/s
Explanation:
Part A
The question is focused on the kinetics equation of a free falling object
The given parameter is the time it takes the rock to hit the ground, t = 5.2 s
For an object in free fall, we have;
h = 1/2·g·t²
Where;
h = The height from which the object is dropped
g = The acceleration due to gravity ≈ 9.8 m/s²
t = The time taken to travel the distance, h = 5.2 s
∴ h = 1/2 × 9.8 m/s² × (5.2 s)² ≈ 132.496 m
The distance travel by the rock, h ≈ 132.496 m
Part B
The speed, 'v', when the rock hits the ground, is given by the following kinematic equation,
v = g·t
∴ v = 9.8 m/s² × 5.2 s = 50.96 m/s
The speed when the rock hits the ground, v ≈ 50.96 m/s.

An object is placed on a surface. A student tries to apply various combinations of forces on the object. Which pair of forces will not move the object?
Answer:
See Explanation
Explanation:
The question is incomplete, as there are no diagrams or options to provide more information to the question.
The general explanation is as follows:
For the object not to move
(1): The forces acting on the object must opposite each other. i.e. if force A acts at the right (or positive direction), force B will act at the left (or negative direction).
(2) The two forces must be equal.
So, for instance:
If the pair of forces are 5N and 5N in opposite directions, the object wil not move.
However, if one of the forces is greater, the object will move towards the direction of the greater force.

Ocean breezes are due to which method of heat transfer?
A. conduction
B. convection
C. greenhouse gases
D. radiation
E. geothermal energy
Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases. The correct option is B.
What is convection?Convection is a method of heat transfer that occurs in fluids (liquids and gases) and involves the movement of material carrying thermal energy. In convection, heat is transferred by the movement of hot fluid from one place to another, which then causes the transfer of heat from the hot fluid to the cooler fluid or surface it comes into contact with.
Convection can occur in two ways:
Natural convection: It occurs due to the density differences caused by temperature variations within a fluid. When a fluid is heated, its density decreases, making it lighter and causing it to rise. As it rises, it cools, becomes denser and falls back down, creating a cycle that is known as a convection current.
Forced convection: In this type of convection, a fluid is forced to flow over a surface or through a channel, by an external agent like a fan or pump. The forced flow enhances the rate of heat transfer from the surface or through the channel, as compared to natural convection, where the fluid flow is driven only by buoyancy forces.
Convection is a very important process for heat transfer in many natural and industrial applications, including heating and cooling systems, meteorology, oceanography, and more.
Here in the Question,
Ocean breezes are primarily due to convection, which is the transfer of heat through the movement of fluids or gases. As the sun heats up the surface of the ocean, the air above it also heats up and rises. This creates a low pressure area that draws in cooler air from over the land, resulting in a breeze that blows from the ocean towards the shore. This is why sea breezes are generally felt during the day, when the land is warmer than the sea, and why they tend to die down at night, when the opposite occurs.
Therefore, The correct answer is B i.e convection.

Harish runs on a straight path with the velocity of 16 m/s . How long distance will he cover in 2 minutes ?
Answer:
Harish went 1.92 Km in 2 minutes.
Explanation:
Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.
We can use this formula to calulate the distance:
m/s x time
We know that Harish is going 16m/s so let's plug that in:
16 (m/s) x time
We also should know that 2 minutes is 120 seconds - Let's plug that in too:
16 (m/s) x 120 (Seconds)
Now we calculate:
16 x 120 = 1920
Harish went 1,920 meters in 2 minutes.
Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.
1 Kilometer (Km) is equal to 1,000 meters.
All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:

How much thermal energy is absorbed when 145 g of water at 23ºC is heated until it boils and turns into vapour?
Answer:
the thermal energy absorbed is 46,893 J
Explanation:
Given;
mass of the water, m = 145 g = 0.145 kg
initial temperature of the water, t₁ = 23 ⁰C
final temperature of the water, t₂ = 100 ⁰C
specific heat capacity of water, c = 4,200 J/kg.⁰C
The thermal energy absorbed is calculated as;
H = mcΔt
H = 0.145 x 4,200 x (100 - 23)
H = 46,893J
Therefore, the thermal energy absorbed is 46,893J
