Explain What the core muscles do and why it's important to have a strong set of core muscles.
Answers
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.

all energy,potential kinetic within a specific system
a)joule
b) total energy
c) potential energy
Answers
Answer:
C
Explanation:
The potential and kinetic energy within a specific system is called the total energy of the system.
Option B is the correct answer.
Potential and Kinetic EnergyThe energy of the specific system due to its steady position is defined as the potential energy of the system.
The energy of the system which is stored due to the motion of the system is called the kinetic energy of the system.
The mechanical energy of the system is the total energy within the system including its kinetic and potential energy.
The sum of kinetic and potential energy is known as mechanical energy. An object's mechanical energy is defined as the total energy which is stored during its steady position and stored during the motion of the object.
Hence we can conclude that option B represents the correct answer for the given statement.
To know more about the potential and kinetic energy, follow the link given below.

A passive continental margin has a ____, while an active margin does not.
O A. continental rise
O B. continental slope
O C. continental duct
O D. continental shelf
Answers
I’m gonna go with A but I might be wrong
A passive continental margin has a continental rise, while an active margin does not. Therefore, option A is correct.
What is passive continental margin?Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
A good example is the east coast of the United States, where the plate boundary is a distance from the shore along the mid-Atlantic ridge. Little geological activity occurs along passive borders.
Volcanoes, mountain belts, and earthquakes all identify active margins. They lack a continental uplift and an abyssal plain, in contrast to passive margins.
The Pacific and North American Plate boundaries are visible along the west coast of the United States, which is an example of an active margin. Where there is no plate border to mark the transition from land to sea, this is known as a passive continental margin.
Thus, option A is correct.

Force (N) = 250
Mass (kg) = 221
Acceleration (m/s^2) = ?
Answers
Answer:
The required acceleration is [tex]a=1.1[/tex] m/s²
Explanation:
Given
Force F = 250 NMass m = 221 kgTo determine
Acceleration a = ?
We know that acceleration is produced when a force is applied to a body.
The acceleration can be determined using the formula
[tex]F = ma[/tex]
where
F is the force m is the mass a is the accelerationnow substituting F = 250 , and m = 221 in the formula
[tex]F = ma[/tex]
[tex]250 = 221 (a)[/tex]
switch the equation
[tex]221(a) = 250[/tex]
Divide both sides by 221
[tex]\frac{221a}{221}=\frac{250}{221}[/tex]
simplify
[tex]a=\frac{250}{221}[/tex]
[tex]a=1.1[/tex] m/s²
Therefore, the required acceleration is [tex]a=1.1[/tex] m/s²

Answers
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
