Answer:
Hello your question lacks some information but i will give you a more General answer about differences in temperature of bodies on same latitude
answer : Continentality is the reason
Explanation:
Sensors or objects on the same latitude are supposed to have the same air temperatures but in some cases this might not be true. This is because of the proximity of the bodies to an Ocean or any water body.
Areas close to water bodies experience modest temperatures even if they are on the same latitude with Areas experiencing harsh temperatures. This effect is termed as Continentality

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.

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

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

what is the equation for net force
Answer:
Is to add all forces, for example either the gf = gravitational force
Ff= force fiction
Fn= normal force
Thus, fg + ff + fn = y will give you results
Well then the forces you use in your exercises or questions.
The equation for net force is: ΣF = ma
or, ΣF = Δp/Δt.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
A spring balance can be used to calculate the Force. Newton is the SI unit of force.
Hence, net force applied on the object = mass × acceleration
ΣF = ma
It can be written in another from as:
net force applied on the object = change in momentum ÷ time interval
ΣF = Δp/Δt
So, the equation for net force is: ΣF = ma
or, ΣF = Δp/Δt.

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.

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:
1.92 Km
Answer:
1.92 km
Explanation:
I will explain you:
2×60=120

A spinning wheel on a fireworks display is initially rotating in a counterclockwise direction. The wheel has an angular acceleration of -4.20 rad/s2. Because of this acceleration, the angular velocity of the wheel changes from its initial value to a final value of -26.0 rad/s. While this change occurs, the angular displacement of the wheel is zero. (Note the similarity to that of a ball being thrown vertically upward, coming to a momentary halt, and then falling downward to its initial position.) Find the time required for the change in the angular velocity to occur.
Answer:
The time it takes for the change in the angular velocity to occur is 6.5 seconds
Explanation:
From the question, we have;
The angular acceleration of the wheel, α = -4.20 rad/s²
The final angular velocity of the wheel, ω = -26.0 rad/s
From the information, we have the initial direction of rotation of the wheel = Counterclockwise
The angular displacement while the change occurs = 0 rad/s
Therefore, the initial angular velocity of the wheel, ω₀ = 0 rad/s
We have;
[tex]\alpha = \dfrac{\omega -\omega _0 }{t - t_0}[/tex]
Where;
t - t₀ = The time it takes for the change to occur
[tex]\alpha = \dfrac{\omega -0 }{t - 0}[/tex]
When t₀ = 0, we have;
t - t₀ = t
[tex]\alpha = \dfrac{\omega }{t}[/tex]
[tex]\therefore t = \dfrac{\omega}{\alpha }[/tex]
[tex]\therefore t = \dfrac{-26 \, rad/s}{-4 \, rad/s^2 } \approx 6.5 \, seconds[/tex]
The time it takes for the change in the angular velocity to occur is t - t₀ = 6.5 seconds

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.
