Answer:Bones,muscles, tendons are part of the musculoskeletal system

Explanation:

Musculoskeletal provides support, form, stability and movement to the body.It is made up of skeletal bones, muscles, cartilages, tendons, ligaments and other connective tissues that supports and binds the organs together.

So from the given list of organs the part of the musculoskeletal system are:

Bones,Muscles, tendons

Selina drops a golf ball down a deep well. The ball falls with only the force of gravity acting on it. Without any air resistanc

ss7ja [257]

Answer: A. constant

Without any air resistance, as the golf ball falls into the well, its speed is constant.

Explanation:

Given that when the ball is released,there is no air resistance acting on ball. So the ball is freely falling. 

The only force acting on the freely falling body is the gravitational force pulling the body towards the centre of the earth.Here the only acceleration acting on the body is the acceleration due to gravity.

The acceleration due to gravity is $9.8 m/s^2$ . so through out the journey of the ball,the acceleration is $9.8 m/s^2$ . So as the acceleration is constant, the speed is also constant.

Arrange the three common unit cells in order from least dense to most dense packing. a. face-centered cubic < body-centered c

maks197457 [2]

Answer:

b. primitive cubic < body-centered cubic < face-centered cubic

Explanation:

The coordination number is defined as the number of atoms (or ions) surrounding an atom (or ion) in a crystal lattice. Its value gives us a measure of how tightly the spheres are packed together. The larger the coordination number, the closer the spheres are to each other.

In the primitive cubic, each sphere is in contact with 6 spheres, so its coordination number is 6.

In the body-centered cubic, each sphere is in contact with 8 spheres, so its coordination number is 12.

In the face-centered cubic, each sphere is in contact with 12 spheres, so its coordination number is 12.

Therefore, the increasing order in density is the primitive cubic first, then the body-centered cubic, and finally the face-centered cubic.

calculate the enthalpy change for converting 1.00 mol of liquid water at 100 C to water vapor at 145 degree celsius for water Δ

Svetllana [295]

Answer:

q1 = mCpΔT

= 18.016g × 1.84J/g.K × (418.15-373.15)

= 1491.72 J

q2 = n×ΔH vap

= 1mol ×44.0kJ/mol

= 44KJ

∴ qtotal = q1+ q2

= 1.498kJ + 44.0kJ

= 45.498KJ

Explanation: The heat flow can be separated into steps.all that is being observed at a constant pressure,the heat flow is equal to the enthalpy.
