Mia plays soccer for her high school team. generally, they start practicing by stretching. The kind of stretching should they do before they are warmed up is Dynamic Stretching

Dynamic Stretching consists of techniques that involve active stretching to reduce force and its negative effects. Muscles are stimulated and made ready for usage during exercise by dynamic stretching.

Dynamic stretching not only stretches the muscles and tissues but also activates and warms up the muscles to get them ready for action.

We require our muscles' flexibility to maintain the range of motion in our joints, so stretching keeps them strong, flexible, and healthy. The muscles shorten and tighten without it. The muscles are then weak and unable to fully expand when you want them to work.

A spinning coil of wire is what moves the cone in a speaker, producing the sound. True/False
Georgia [21]

False, the spinning coil of wire that moves the cone in a speaker does not produces sound.

<u>Explanation</u>:

The wire coil is an electromagnet that is fixed to speaker cone. A normal magnet attached to the back of the speaker cone.When audio is sent in the form of short bursts of electric current to the speaker cone through the wire.

A magnetic field is induced when electric current allowed to pass through the coil. This magnetic field is repelled by the other magnet. This repulsion cause the cone to move forward. In the absence of  electric current in the coil, the cone moves backward.

Thus sound waves are produced due to the resulting rarefaction and compression.  So it is not the spinning coil of wire but he permanent magnet that produces the sound.

How are newtons third law and his law of universal gravitation are connected
Nutka1998 [239]

Answer:

please give me brainlist and follow

Explanation:

Gravitational force keeps it attracted to the Earth, and centripetal force keeps it moving in a circle. ... Explain how Newton's third law and his law of universal gravitation are connected. His third law states that every force has an equal opposite force attracted to it, and that force is caused by gravity.

Answer:

When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.

A 0.210-kg metal rod carrying a current of 11.0 A glides on two horizontal rails 0.490 m apart. If the coefficient of kinetic fr
sergij07 [2.7K]

Answer:

The  magnetic field is  B = 0.0764 \ T

Explanation:

From the question we are told that  

    The mass of the metal is  m  =  0.210 \ kg

     The current is  I  =  11.0 \ A

      The distance between the rail(length of the rod ) is  d  =  0.490 \ m

      The coefficient of kinetic friction is  \mu_k  =  0.200

Generally the magnetic force is mathematically represented as

      F_b  =  B *  I  *  d

Given that the rod is moving at a constant velocity, it

=>    F_b  =  F_k

Where F_k is the kinetic frictional force which is mathematically represented as

       F_k  =  \mu_k  *  m *  g

So

    B *  I  *  d =  \mu_k  * m * g

=>   B =  \frac{\mu_k  * m * g}{I  *  d }

substituting values

=>   B =  \frac{0.200  * 0.210  * 9.8 }{ 11  *  0.490 }

=>   B = 0.0764 \ T
