The answer is a. endothermic.
In endothermic reaction, as the name suggests, the reactants require energy absorption to form and complete the chemical reaction to form products.
And even if you don't know the answer, you can exclude all other answers by scientific logic and you will be left with the correct answer.
Hope this helps.
Potential energy at any point is (M G H). On the way down, only H changes. So halfway down, half of the potential energy remains, and the other half has turned to kinetic energy. Half of the (M G H) it had at the tpp is (0.5 x 9.8 x 10) = 49 joules.
Answer: <em>An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.</em>
Explanation: meaning, an object will continue in its same direction until stopped or acted upon by another force.
About 50 years ago, mounting evidence was suggesting
that the temperature of Earth's surface has been sharply
increasing for the past couple of centuries. Nowadays,
additional evidence no longer suggests it; it confirms it.
Today's mounting evidence suggests that human activity is
responsible for the increase, but that the increase eventually
spells curtains for much of human activity.
Well if you take 10 minutes to walk each mile and you don't stop by continuously walking... it would take approximately 69 and a half daysSource(s):<span>10 minutes x 10,000 miles= 100,000 minutes
100,000 minutes/ 60 minutes (1 hour)= 1,666.66667 hours
1,666.66667 hours/ 24 hours (1 day)= 69.4444446 days
69.4444446 days rounds to 69.5 days which means that would be about 2 months and a week.</span>
