Temperature can be described as an indirect measure of heat energy
So therefore your answer should be letter C
Well we know the hypotenuse of the triangle which is 253 m. And we know the angle of the triangle which is 55.8 degrees. So we want to find y. And to find y we use sin. And sin is a ratio, the ratio of the opposite leg, and hypotenuse. So sin(55.8) = y/253. Now we solve for y by multiplying both sides by 253. And finally we get 209.25 as the length of the y component.
Answer:
Explanation:
Since there's no external force beside gravity acting on the rod, we can use the law of energy conservation to calculate for the speed of rod center of gravity before hitting the surface.
Also as the rod is uniform and this, its center of gravity is at distance h/2 from the surface.
Complicated 2-step process.
<span>1. Write down the formula for "frequency of a pendulum" from your textbook. </span>
<span>f = (1/2pi) * sqrt(g/L) </span>
<span>2. Plug in g and L.
I hope this can help!</span>
I believe the answer would be A, gravity.
