Sound energy is one example
Answer:
KE increases and PE decreases.
Explanation:
<u>POTENTIAL ENERGY (PE)</u>:
The potential energy of the rock depends upon the height of the rock, as given by the following formula:
P.E = mgh
Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its <u>potential energy will also decrease</u>.
<u>KINETIC ENERGY (KE)</u>:
The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:
Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its <u>kinetic energy will also increase</u>.
Hence, the correct option will be:
<u>KE increases and PE decreases.</u>
Answer:
Screaming is an emotional response triggered by the brain which receives information about the pain later as compared to pulling away of finger which is a reflex action facilitated by the spinal cord that has a quicker-time to response.
Explanation:
Reflex action happens when part of our body comes to contact with an object which can cause harm and you tend to quickly withdraw that part of the body.Reflex action happens quicker before the brain gets the time to process information about the harm.
When the baby touched the hot pan, at point of contact, skin receptors send nerve impulses to the spinal cord. Interneurons in the spinal cord relay a response to motor neurons to stimulate muscle contraction making the baby to pull his finger away.This happens so fast before the brain receives the message later to trigger emotional response(screaming).
Remembering back to science I believe that temperature is on the Kelvin scale. The corresponding temperature on the Celsius scale would be very close to zero degrees which is the freezing point. The corresponding temperature on the Fahrenheit scale would be 32 degree which again is the freezing point.
The aquarium can hold 2750 liters because 1 cubic meter equals 1000 liters.
