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.

. Calculate the weight of a 7 kg object.
Answer:
68.6N
Explanation:
Given parameters:
Mass of object = 7kg
Unknown:
Weight = ?
Solution:
The weight is the downward force of gravity on a body;
Weight = mass x acceleration due to gravity
Weight = 7 x 9.8 = 68.6N

Why do you think that if you drop two balls, exactly two balls rise on the other side at a
similar speed?
Answer:
It conserves both energy and momentum in the collision at the same time. By design, when the balls collide the strings that hold them up are vertical (assuming balls are only swung from one side).
Explanation:
Hope This Helps!!

in what way is Speed related to Kinetic Energy?
Answer:
It turns out that an object's kinetic energy increases as the square of its speed
Explanation:
A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph.
basiclly the faster the more impact it has when it suddenly stops or hit somthing
A photovoltaic cell produces electricity when the sun shines. What energy conversion is going here?
Answer:
light potential energy is converted into electrical potential energy.
Explanation:
A solar heat absorbs the light that creates pairs of electron - holes, these free charges when moving create a current, the light energy stored in the radiation is converted into electrical energy within the n-p junctions.
In summary, light potential energy is converted into electrical potential energy.
A 136 kg defensive lineman is about to tackle a 100 kg quarterback. Right before
impact, the lineman is moving north at 6.0 m/s and the quarterback is moving
north at 1.0 m/s. Determine the speed and direction of the two players
immediately after the tackle.
Answer:
3.88 m/s North
Explanation:
We are given that
[tex]m_1=136kg[/tex]
[tex]m_2=100 kg[/tex]
[tex]v_1=6 m/s[/tex]
[tex]v_2=1m/s[/tex]
We have to find the speed and direction of the two players
immediately after the tackle.
Using linear conservation of momentum
[tex]m_1v_1+m_2v_2=(m_1+m_2)v[/tex]
Substitute the values
[tex]136\times 6+100\times 1=(136+100)v[/tex]
[tex]916=236v[/tex]
[tex]v=\frac{916}{236}[/tex]
[tex]v=3.88m/s[/tex]
Direction of the two players immediately after the tackle is North.

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.
