What connects our muscles to our bones?

Physics
1 answer:
Elina [12.6K]3 years ago
5 0

Answer:

Tendon connects our muscles to our bones.

Explanation:

A tendon (or sinew) is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.

Tendons are similar to ligaments and fasciae; all three are made of collagen.

Ligaments join one bone to another bone; fasciae connect muscles to other muscles.

Tendons and muscles work together to move bones.

The tendon is the part of the muscle that connects directly to the bone.

The motor of a ski boat generates an average power of 2.74 × 10^4 W when the boat is moving at a constant speed of 14.3 m/s. Whe
Roman55 [17]

Answer:

T = 4517.48 N

Explanation:

It is given that,

Average power of the motor, P_1=2.74\times 10^4\ W

Speed of the boat, v_1=14.3\ m/s

Force or tension acting on the motor at this point is given by :

P=T\times v

T=\dfrac{P_1}{v_1}

T=\dfrac{2.74\times 10^4}{14.3}

T = 1916.08 N

Average power generated by the engine, P_2=9.2\times 10^4\ W

Force or tension acting on the motor at this point is given by :

P=T\times v

T=\dfrac{P_2}{v_2}

T=\dfrac{9.2\times 10^4}{14.3}

T = 6433.56 N

So, the tension in the tow rope that is pulling the skier is, T = 6433.56 N - 1916.08 N = 4517.48 N

An electron in an atom's orbital shell, labeled X in the model below, released enough energy to move to a different orbital shel
Delicious77 [7]

Answer:

Lower energy shell which will be nearer to the nucleus.

Explanation:

When electron move from one energy level to another, an electron must gain or lose just the right amount of energy.

When atoms releases energy, electrons move into lower energy levels.  The electrons in the shells aways from the nucleus have more energy as compared to the electrons in the nearer shells.

Electrons with the lowest energy are found closest to the nucleus, where the attractive force of the positively charged nucleus is the greatest. Electrons that have higher energy are found further away

A proton moves along the x-axis with vx=1.0×107m/s. As it passes the origin, what are the strength and direction of the magnetic
Sunny_sXe [5.5K]

Answer:

Magnetic field will be ZERO at the given position

Explanation:

As we know that the magnetic field due to moving charge is given as

B = \frac{\mu_0 qv sin\theta}{4\pi r^2}

so here we know that for the direction of magnetic field we will use

\hat B = \hat v \times \hat r

so we have

\hat B = \hat i \times (\hat i + 0\hat j + 0\hat k)

so magnetic field must be ZERO

So whenever charge is moving along the same direction where the position vector is given then magnetic field will be zero
