The answer is external stimulus
Answer:
B.
Explanation:
Which of the following describes the outer core?
A. The solid, rocky layer on the outside
B. A layer of liquid metal that spins
C. A dense layer of solid metal
D. Hot, partially melted rock that flows
Because the outer core is the third layer of the Earth. It is the only liquid layer, of metals irons and nickel Also its responsible for Earths magnetic field as earth spins on its Axis the substances move also move around during that
<span>when athletes exercise,or their body works out, they intake more oxygen and let out more canbon di oxide. So their heart pumping speed increases which results in higher breathing rates and higher pulse. So they are physically more fit than a person who doesn't workout.</span>
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
