How can a volcano develop in the middle of a tectonic plate?
Answer:
Volcanoes that form away from plate boundaries are created by hotspots. A hotspot is an area in the mantle that is believed to be somewhat hotter than the surrounding material. The rising magma from the hotspot can push its way through the crust and burst out at the surface, forming a volcano.
Explanation:
Volcanoes can form in subduction zones, which are regions where tectonic plates are interacting one and plate is sinking beneath the other.
Essay about how volcanoes form.A volcano is a hill or mountain in the shape of a cone that is erected around a fissure in the surface of the earth thru which heated gases, rock fragments, and lava are released. A conical mass grows around the conduit as the solid fragments gather there, becoming progressively larger until it reaches the size of a gigantic volcanic mountain.
Explain what a volcano is.A volcano is an aperture or vent through which magma, tephra (small rocks), or steam are released onto the the planet's surface. Days, weeks, or even years might pass between outbursts of volcanoes.

Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.
Explanation:
Answer:
The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

On the way home from school, you notice the speedometer on the car is at 5,200 miles. When you get home, the speedometer reads 5,208 miles. With only this information what value could you calculate?
O Velocity
O Displacement
O Acceleration
O Distance
Answer:
O Distance
Explanation:
With the given information, it is possible to find the distance of the car has traveled on the home from school.
This is possible because distance is the length of path a body covers.
From the given values:
Distance = 5208 - 5200 = 8miles
It is not possible to find the displacement because no direction was given.
Also velocity is not possible since the time frame of travel was not state.

why is water further away from the shore colder the further you go?
Answer:
★ For example, cold water has a higher density than warmer water. In Addition, water gets colder with depth because of the coldness, of the salty ocean water which sinks to the bottom of the ocean basins below the less dense water near the surface

what is the formula for acceleration?
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
An object accelerates at 8 m/s^2 when a force of 40 Newtons is
applied to it. What is the mass of the object? (Use formula: m=Fla)
Answer:
5 kg
Explanation:
Acceleration = 8 m/s^2
Force = 40 N
Force = mass * acceleration
mass = force / acceleration
mass = 40 / 8
mass = 5 kg
A 50 kg bumper car with a 40 kg child and it is at rest when a 60 kg child in her own bumper car slams into it the collision last point1 seconds and the rubber bumpers are perfectly bouncy with no heating from the collision what is the force experienced by the first car
Answer:
F = 99 v₂₀
v₂₀ = 1 m / s, F = 99 N
Explanation:
In this exercise it is asked to find the force during the collision, for this we use the relationship between the momentum and the momentum of car 1
I = Δp
F t = p_f- p₀
F t = m (v_f -v₀) (1)
We must find the final speed of car 1, for this we define a system formed by the two cars, in this case the forces during the collision are internal and the moment is conserved
initial instant. Before the crash
p₀ = 0 + m₂ v₂₀
final instant. After the crash
p_f = m₁ v₁ + m₂ v_{2f}
the moment is preserved
p₀ = p_f
m₂ v₂₀ = m₁ v_{1f} + m₂ v_{2f} (2)
m₂ (v₂₀ - v_2f}) = m₁ v_{1f}
as the collision is elastic the kinetic energy is also conserved
K₀ = K_f
½ m₂ v₂₀² = ½ m₁ v_{1f}² + ½ m₂ v_{2f}²
m₂ (v₂₀² -v_{2f}²) = m₁ v_{1f}²
let's write our system of equations, using
a² - b² = (a + b) (a-b)
m₂ (v₂₀ - v_{2f}) = m₁ v_{1f}
m₂ (v₂₀ -v_{2f}) (v₂₀ + v_{2f}) = m₁ v_{1f}²
to solve we divide the equations
v₂₀ + v_{2f} = v_{1f}
with this we substitute in equation 2 and find the speed of each car, in this case we need the speed of car 1
m₂ v₂₀ = m₁ v_{1f} + m₂ (v_{1f}-v₂₀)
2m₂ v₂₀ = (m₁ + m₂) v_{1f}
v_{1f} = [tex]\frac{2m_2}{m_1+m_2} v_{2o}[/tex]
We substitute in the drive ratio of car 1
F t = m (v_f -v₀)
F = m₁ (\frac{2m_2}{m_1+m_2} v_{2o} - 0) / t
F = [tex]\frac{2m_1 m_2 }{m_1+m_2} \ \frac{v_{2o}}{t}[/tex]
the mass of each car is the mass of the car plus the mass of the boy
m₁ = 50 +40 = 90 kg
m₂ = 50 +60 = 110 kg
time is t = 1
we substitute the values
F = [tex]\frac{ 2\ 90 \ 110}{90+110} \ \frac{v_{2o}}{1}[/tex]2 90 100/90 + 110 vo2 / 1
F = 99 v₂₀
The value of the initial velocity of car 2 is not indicated in the problem, if this velocity is known it can be included and the force value is obtained, suppose that the initial velocity v₂₀ = 1 m / s
F = 99 N

The energy the Sun gives off is caused by nuclear reactions in its core. The extreme pressure from the weight of the gases that make up the Sun raises the temperature of the core enough for the nuclear reactions to take place. Which law best describes this behavior of gases in the Sun?
Answer:
The law which describes the behavior of gases in the Sun is Gay-Lussac's Law
Explanation:
The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;
Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;
P ∝ T
The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;
P = K·T
∴ P/T = K (Constant)
[tex]\therefore \dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}[/tex]

ANSWER ASAP Which factor determines the amount of gas that can dissolve in ocean water? (A) the motion of the air above the ocean water (B) the temperature of the air above the ocean water (C) the motion of the ocean water currents D the temperature of the ocean water
Answer:
The amount of each gas that can dissolve in the ocean depends on the solubility and saturation of the gas in water. Solubility refers to the amount of a dissolved gas that the water can hold under a particular set of conditions, which are usually defined as 0o C and 1 atmosphere of pressure.

The location of the fulcrum can magnify (or reduce) the force applied at one end at the expense (or advantage) of the distance over which the other end travels. Sorry if I get this wrong! I am in 5th grade. ♥
The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Answer:
True.
Explanation:
The given statement is true that the law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
According to this law, the forces between two masses can be calculated by the product of their masses and divided by the square of the distance between them. Mathematically, it can be written as :
[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]
G is universal gravitational constant
Hence, the given statement is true.
The net force acting on this object is 200N to the left. What is the force of friction and air resistance combined if the thrust force is 500N?
Answer:
Explanation:
Force of friction and air resistance acts against the external force . Let it be f .
net force = external force - frictional force and air resistance
Putting the given values
200 = 500 - f
f = 500 - 200 = 300 N .
Hence force of friction = 300 N .
