When you heat something of cool it down you don't change the substance you might change the why is looks, but it is still the same substance. For example you cool water to 0 degrees Celsius it turns into ice but it still is two parts hydrogen and one part oxygen H2O. Physical changes will change state and/or form but it will still be what it originally was on the molecular level. Hope that helped.
Water was confirmed to be on the sunlit surface of the Moon
The heart rate will likely decrease. As the cardiac muscle, or heart, gets stronger, it takes less effort to pump more blood. As a result, the heart will probably beat less, decreasing the heart rate. This is why athletes often have lower heart rates than the average person.
The answer would be Newton’s Second Law
Answer:
Explanation:
Given that:
- moment of inertia of tucked body,
- rotational speed of the body,
- i.e.
- moment of inertia of the straightened body,
<u>Now using the law of conservation of angular momentum:</u>
angular momentum of tucked body=angular momentum of straight body
