When a pot of water sits on a hot stove the metal is He did and then transferred into heat to the world of student claims that conduction is the only type feet transfer occurring which statement explains why the students idea is incorrect
Answer:
Hello your question is poorly written hence I will just give the difference between conduction and convection
answer :
Conduction occurs when there is direct contact between solids and source of heat. while convection occurs when there is transfer of thermal energy due to movement of liquid or gas
Explanation:
when a pot of water is placed on a hot stove the pot is heated through conduction because the metal pot is in direct conduct with the heat from the stove ( which is the primary source of heat in this scenerio ).
while the heat transfer from the hot pot to the water is executed through convection this is because heat transfer via convection requires the movement of liquid or gas. as the warmer liquid moves over to the top the cooler liquid goes below inside the pot that way the whole liquid becomes warm .
Two beakers are at the same temperature. One beaker has more water than the other. Which one contains more heat? Explain why.
Answer:
I would say the beaker with less water.
Explanation:
I was say this because while they are the same temperature the beaker with more water still has to fluctuate the heat or cold. They do this at the same speed but since there is less water in one beaker it finishes faster where as the beaker with more water will finish later.

Two thin lenses of power +3.5 D and -2.5 D are placed in contact,
find the power and focal length of the lens combination.
Answer:
P = 1 D
f = 1 m = 100 cm
Explanation:
The power of the combination of lenses is simply found out by adding the power of the individual lens:
[tex]P = P_{1}+P_{2}[/tex]
where,
P = Power of combination of lenses = ?
P₁ = Power of first lens = 3.5 D
P₂ = Power of second lens = -2.5 D
Therefore,
[tex]P = 3.5\ D - 2.5\ D[/tex]
P = 1 D
Now, for focal length:
[tex]Focal\ Length = f = \frac{1}{D}\\\\f = \frac{1}{1\ D}[/tex]
f = 1 m = 100 cm

You and a friend each apply 500 N of force to move a cement block 50 cm. How much work was done on the cement block?
Answer:
W = 500 J
Explanation:
Work is defined by
W = F . x
if we develop the dot product
W = F x cos θ
where is the angle between the force and the displacement, in this case the angle is zero, so cos 0 = 1
W = F x
indicate that each person applies a force of 500 N, so the total force is
F = 1000 N
let's reduce the distance to the SI system
x = 50 cm = 0.50 m
let's calculate
W = 1000 0.50
W = 500 J

Your friend has a mass of 70 kg and is running at a velocity of 3 m/s. What is their kinetic energy?
Answer:
TINAAA
Explanation:
I need help again!!!!!! Due today!!!! NO LINK PLEASE
Answer:
The Acceleration of the object = 6.4 m/s²
Explanation:
Mass of block (m) = 5 kg
Action force on block, (F₁) = 40 N
To Find:
Acceleration of the object (a) = ?
Required solution:
Frictional force opposing the motion (F₂) = 8 N
Here in this question we have to find Acceleration of the object. So, firstly we have to find Net force of block after that we will find Acceleration of the object on the basis of conditions given above
⇒ Net force = Action force on block - Opposing friction force
⇒ F = F₁ - F₂
⇒ F = 40 - 8
⇒ F = 32 N
Now, we have to two elements that used in formula, Net force and Mass of block.
Net force of the block (F) = 32 N
Mass of block (m) = 5 kg
And we have to find Acceleration of the object.
We can find Acceleration of the object by using the Second law of Newton which says F = ma
Here,
F is the Force in N.
m is the Mass in kg.
a is the Acceleration in m/s².
So let's find Acceleration (a) !
† From second law of Newton
⇛ F = ma
⇛ a = F/m
⇛ a = 32/5
⇛ a = 6.4 m/s²

A cloud is drifting across the sky at a constant velocity of 724metersperminute to the east. It is at an altitude of 9,200 meters. How far will the cloud move in 12.5minutes?
Answer:
The cloud moves 9050 meters to the east in 12.5 minutes.
Explanation:
Let suppose that mass of the cloud is negligible. meaning that effects of gravity are negligible and that altitude of the cloud remains constant. If the cloud drifts at constant velocity, travelled distance is defined by following formula:
[tex]\Delta s = v\cdot \Delta t[/tex] (1)
Where:
[tex]v[/tex] - Velocity, in meters per second.
[tex]\Delta t[/tex] - Time, in seconds.
If we know that [tex]v = 724\,\frac{m}{min}[/tex] and [tex]\Delta t = 12.5\,min[/tex], then the travelled distance after 12.5 minutes is:
[tex]\Delta s = 9050\,m[/tex]
The cloud moves 9050 meters to the east in 12.5 minutes.
The part of the lithosphere under the ocean are less dense then those under the continents. True or false
Answer:
False
Explanation:
The outer part of the Earth that is hard and solid is termed as lithosphere. It is the outermost part of the Earth's surface. The lithosphere covered under the oceans is the oceanic lithosphere while the lithosphere comprising the continental area is the continental lithosphere. Oceanic lithosphere is denser than the continental lithosphere because of the thin layer of the Earth that exists under the oceans.
Hurricanes are powered by heat energy in the atmosphere and the ocean. Typically, one hurricane uses an amount of heat roughly equal to Z thousand atomic bombs. If the excess heat built up in Earth's atmosphere since 1850 went into producing hurricanes, about how many more hurricanes might we expect in the world every year?
Answer:
In an year about 6 major hurricanes and 3 minor storms occurs.
Explanation:
Hurricanes are increasing in number and frequency to the increasing impact of global warming. As current research states that climate change in the tropics results in an increased storm frequency. The presence of extra heat in the air or the oceans form the stoma that leads to the production of such energy. According to o the 200-2007 data shows in the huge increase in the storm frequency and this suggests the impact of climate warming.Suppose you have a 34.9 m length of copper wire. If the wire is wrapped into a solenoid 0.240 m long and having a radius of 0.0510 m, how strong is the resulting magnetic field in its center when the current is 11.0 A?
Answer:
the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.
Explanation:
Given;
length of the wire, = 34.9 m
length of solenoid, L = 0.24 m
radius of the solenoid, r = 0.051 m
current in the solenoid, I = 11.0 A
The number of turns of the wire is calculated as follow;
[tex]N = \frac{34.9}{2\pi \times 0.051} = 109 \ turns[/tex]
The strength of the magnetic field inside the solenoid is calculated as follows;
[tex]B = \mu_0 (\frac{N}{L} )I\\\\B = 4\pi \times 10^{-7} \times (\frac{109}{0.24} )\times 11.0 \\\\B = 6.278 \times 10^{-3} \ T[/tex]
Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.

A roller coaster car is traveling at a constant 3 m/s when it reaches a downward slope. On the slope, the car accelerates at a constant rate of 4.5 m/s 2 . The length of the slope is 45 meters. A) Find the velocity of the car at the bottom of the hill. B) Find the time of travel.
Answer:
Velocity of the car at the bottom of the slope: approximately [tex]20.3\; \rm m \cdot s^{-2}[/tex].
It would take approximately [tex]3.9\; \rm s[/tex] for the car to travel from the top of the slope to the bottom.
Explanation:
The time of the travel needs to be found. Hence, make use of the SUVAT equation that does not include time.
Let [tex]v[/tex] denote the final velocity of the car. Let [tex]u[/tex] denote the initial velocity of the car.Let [tex]a[/tex] denote the acceleration of the car. Let [tex]x[/tex] denote the distance that this car travelled.[tex]v^2 - u^2 = 2\, a\cdot x[/tex].
Given:
[tex]u = 3\; \rm m \cdot s^{-1}[/tex].[tex]a = 4.5\; \rm m \cdot s^{-2}[/tex].[tex]x = 45\; \rm m[/tex].Rearrange the equation [tex]v^2 - u^2 = 2\, a\cdot x[/tex] and solve for [tex]v[/tex]:
[tex]\begin{aligned}v &= \sqrt{2\, a \cdot x + u^2} \\ &= \sqrt{2 \times 4.5\; \rm m \cdot s^{-2} \times 45\; \rm m + \left(3\; \rm m \cdot s^{-1}\right)^{2}} \\ &\approx 20.3\; \rm m \cdot s^{-1}\end{aligned}[/tex].
Calculate the time required for reaching this speed from [tex]u = 3\; \rm m \cdot s^{-1}[/tex] at [tex]a = 4.5\; \rm m \cdot s^{-2}[/tex]:
[tex]\begin{aligned}t &= \frac{v - u}{a} \\ &\approx \frac{20.3\; \rm m \cdot s^{-1} - 3\; \rm m \cdot s^{-1}}{4.5\; \rm m \cdot s^{-2}} \approx 3.9\; \rm m \cdot s^{-1}\end{aligned}[/tex].

Mine was swaying perfectly fine. after a little bit it gradually started swinging slower until stopped.
B: Why did the pendulum stop swinging? Where did the energy go?
gravity was pulling it towards the ground, however the weight and momentum of the ball helped it keep swinging for a good while.
C: Scientists have organized all forms of energy into two types—kinetic and potential. Kinetic [THE ENERGY OF MOTION IN A BODY] energy is the energy of motion, and potential energy [THE STORED ENERGY IN AN OBJECT] is stored energy. At the top of its swing, does the pendulum have kinetic or potential energy?
when its at the very top of the swing it does have a very small amount of time until it starts going back down again but during that time it is potential energy
D: At the bottom of its swing, does the pendulum have kinetic or potential energy?
the pendulum still has kinetic energy when it is the closest to the ground since it is still swinging
E: Think about the process of raising the pendulum to one side and letting it go. For this event, create a list of each form of energy associated with the pendulum as it cycles.
when its in my hand: potential energy
when it starts swinging: kinetic energy
when its going upwards: kinetic energy
when it stops swinging: potential energy
F: How could you give the pendulum more energy?
one way you could possibly make it have more energy is if you make the string longer
G: Now raise the pendulum and let it hit a metal lid or pan. When the ball strikes the lid, what forms of energy can you identify?

If a motorcycle, a car, and a big rig are all moving with a velocity of 100 km/h, which vehicle has the greatest momentum? A motorcycle and rider. A small car. A large 18 wheeler truck.
Answer:
The big rig.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
In this scenario, a motorcycle, a car, and a big rig are all moving with a velocity of 100 km/h. Thus, the vehicle which has the greatest momentum is the big rig because its mass is intuitively or logically greater than that of the other vehicle.
Generally, momentum is directly proportional to the mass of a physical object or body.
Answer: A large 18 wheeler truck.
Explanation: Momentum is the measure of the motion of an object found by multiplying the object’s mass and velocity. Momentum is directly proportional to the object's mass and also its velocity. So, the greater an object's mass or the greater its velocity, the greater its momentum. Therefore, since the truck is bigger, it has the greatest mass. This means that the truck the greatest momentum. Correct on Edg 2020.
