The key benefits to this is the athlete thinks and reflects for themselves which is a vital part of the Learning Styles Model. This technique is most useful for more experienced athletes who like to have involvement and their own opinions about their performance.

A 0.772 kg glass jar falls off a shelf

Andrew [12]

Answer:

1.48m

Explanation:

Info given:

mass: 0.772kg

PE = 11.2J

g = 9.81m/s^2

Using KEbottom = PEtop

PE = mgh

Plug in and solve for h (height)

11.2J = mgh

h =11.2J / mg

h = 11.2J / (0.772kg)(9.81m/s^2)

h = 1.48m

Relate temperature to the average kinetic energy in a material.

inn [45]

Answer:

Temperature is always directly proportional to average kinetic energy of the material.

Explanation:

The average kinetic energy is given by the formula

$\mathrm{K}=\frac{3}{2} \frac{R}{N A} T$

Where K = average kinetic energy . R = gas constant , NA = avogadro's number, T = temperature

From the formula we can clearly see that K is directly proportional to T i.e kinetic energy increases with increase in temperature.

As a substance when it absorbs the heat , temperature increases which makes the faster movement of the particles thus increasing the kinetic energy.The above formula is applicable to gaseous molecules.
