A physics student shoves a 0.50-kg block from the bottom of a frictionless 30.0° inclined plane. The student performs 4.0 j of w

Musya8 [376]

Answer:1.63 m

Explanation:

Given

mass of block $m=0.5 kg$

inclination $\theta =30^{\circ}$

Amount of work done $W=4 J$

block slides a distance s along the Plane

Work done =change in Potential Energy

Increase in height of block is $s\sin \theta$

Change in Potential Energy $=mg(\sin \theta -0)$

$\Delta P.E.=0.5\times 9.8\times s\sin 30$

$4=0.5\times 9.8\times s\sin 30$

$s=\frac{4}{2.45}$

$s=1.63 m$

Which process is associated with an increase in kinetic energy, and what experimental evidence supports this?

Alinara [238K]

Answer:

Option B: the period during which a solid is not changing state; its temperature is increasing

Explanation:

The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)

Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.
