Answer:
<h2>compression</h2>
Explanation:
Such type of the longitudinal waves that causes compression during the travelling through the medium is called as compression. Generally, displacement of the medium takes place in this wave travelling conditions. There are many waves that are considered as longitudinal waves such as sound waves, seismic p-waves and some other. Waves have different types of properties that are changed due to different medium.
Answer:
System inputs and outputs fluctuate around a stable average so the system does not move far from its average condition.
Explanation:
Steady-state equilibrium can also be called dynamic equilibrium. The main difference between the two is the type of system we are considering. When a system is closed, and it attains equilibrium, there is no transfer of energy. In the case of an open system, even if the system achieves equilibrium there will be some transfer of energy but it will not deviate far from it's equilibrium point, that is, it will be in a steady-state.
Answer:
True
Explanation:Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
The change in gravitational potential energy is A) 15.68 J
Explanation:
The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
The change in gravitational potential energy of an object is given by the equation:
where
m is the mass of the object
is the acceleration due to gravity
is the change in height of the object
In this problem, we have
m = 2 kg is the mass of the frame
is the change in height
Substituting, we find:
