The specific heat capacity of the block is 
Explanation:
As the block is placed into the water, heat energy is transferred from the water (which is at higher temperature) to the block (which is at lower temperature), until the block and the water are in thermal equilibrium (= same temperature).
Therefore, we can write:
Where
is the heat energy released by the water, where
is the mass of the water
is the water heat specific capacity
is the initial temperature of the water
is the temperature at equilibrium
Substituting,
Now we can write the heat energy absorbed by the block as
where
is the mass of the block
is the specific heat capacity of the block
is the initial temperature of the block
And solving for ,

Answer:
- creation of mid-ocean ridges
-creation of new mountains
-formation of earthquakes
-formation of volcanoes
Convergent boundary plate tectonic involves collisions between oceanic and continental plates. The thinner and less denser oceanic plate overriden by the thicker and more denser continental plate. The oceanic plate is forced down the mantle, this event is known as subduction. The magma present in the mantle causes melting of subduction plates. The magma enters inside these plates through pores. This magma plate becomes bouyant and moves upwards. The molten magma causes volcanic eruptions along with earthquakes. If the magma solidifies in the subduction zone it creates mid ocean ridges. The mountains are formed near the continents when the magma after volcanic eruption gets cooled and solidified.
Work is force times distance. So here we have
W=(5000N)x(3000m)=1.5x10^7J
Or 15MJ (megajoules)
Answer: It opposes the flow of electrons.
Explanation: just did the quiz on
Answer:They may cause motion to change
Explanation:They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.
