Answer:
heat energy
Explanation:
heat is the flow of thermal energy. A whole branch of physics
Answer:
<em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N </u></em><em><u>and </u></em><em><u>F2 </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
Explanation:
<em>Formula </em><em>used </em><em>=</em><em>></em><em> </em><em> </em><em>F </em><em>=</em><em> </em><em>m×</em><em>a</em><em> </em><em>and </em><em>v-u=</em><em> </em><em>at</em>
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
<em>FOR </em><em>1</em><em>S</em><em>T</em><em> </em><em>BLOCK</em>
16= <math> F1/5 </math> × 5 ==> <em><u>F1 </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>6</u></em><em><u> </u></em><em><u>N</u></em>
<em>FOR </em><em>2</em><em>N</em><em>D</em><em> </em><em>BLOCK</em>
15= <math> F2/ 8 </math> × 5 ==> <em><u>F2=</u></em><em><u> </u></em><em><u>2</u></em><em><u>4</u></em><em><u> </u></em><em><u>N</u></em>
Larger than one.
In fact, the index of refraction of a medium is the ratio between the speed of light in vacuum (c) and the speed of light in that medium (v):
But the maximum speed the light can travel at is exactly c, the speed of light in vacuum: so v is always less (or equal, in case of vacuum) than c, and so n is always greater than 1.
