Answer:

Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.

Explanation:

Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)

When driving at night, only use your high-beam headlights___
zzz [600]

Answer:

B

Explanation:

While answer C may sound correct, Answer B is makes more sense. We know you cant use High-beam lights when u cant see ongoing traffic because it could affect the other driver coming across from you. Its good to use it when legal and safe, but in that term I still don't believe there's no reason for HIGH-beamed. That's this leaves B, when you are on u lighted streets.

A 3.59 kg block is released from rest 53.0 m above the ground. When it has fallen 21.3 m, what is its kinetic energy
Juli2301 [7.4K]
<h3><u>Answer:-</u></h3>

\implies1115.2 Joules

<h3><u>Given :- </u></h3>

\red{\leadsto}\:\textsf{Height\: at \:rest\:}\sf,h_2= 53.0m

\green{\leadsto}\:\textsf{Height\: to\:which\;block\:}\sf,h_1= 21.3

<h3><u>Solution</u> :-</h3>

\malteseAs the block falls , the change in potential energy will be converted into kinetic energy

\leadstoPotential Energy at rest at height,h_2 = \sf mgh_2

\leadstoPotential Energy when fell at height,h_1 = \sf mgh_1

\\

\leadstoKinetic energy= Change in Potential energy = = \sf mgh_2-mgh_1

\begin{gathered}\implies\quad \sf mg(h_2-h_1) \\\end{gathered}

\begin{gathered}\implies\quad \sf mg(53.0-21.3) \\\end{gathered}

\begin{gathered}\implies\quad \sf 3.59 \times 9.8\times (53.0-21.3) \\\end{gathered}

\begin{gathered}\implies\quad \sf 3.59 \times 9.8\times 31.7\\\end{gathered}

\begin{gathered}\implies\quad  \boxed{\sf{1115.2\: Joules}}\\\end{gathered}
