The chemical change is are to water breaking down into hydrogen and oxygen.
Answer is D.
A tsunami is a series of waves generated in an ocean or other body of water by a disturbance such as an earthquake, landslide, volcanic eruption, or meteorite impact. ... Undersea earthquakes, which typically occur at boundaries between Earth's tectonic plates, cause the water above to be moved up or down
Answer:
solid cylinder
Explanation:
the object that arrives first is the object that has more speed, let's use the concepts of energy
starting point. Highest point
Em₀ = U = m g h
final point. Lowest point
Em_f = K = ½ mv² + ½ I w²
since the body has rotational and translational movement
how energy is conserved
m g h = ½ mv² + ½ I w²
linear and angular velocity are related
v = w r
w = v / r
we substitute
m g h = ½ mv² + ½ I (v/r) ²
mg h = ½ v² (m + I /r²)
v =
the tabulated moments of inertia for the bodies are
solid cylinder I = ½ m r²
hollow cylinder I = m r²
we look for the speed for each body
solid cylinder
v₁ =
v₁ =
let's call v₀ =
v₁ = 0.816 v₀
hollow cylinder
v₂ =
v₂ = v₀ √½
v₂ = 0.707 v₀
Therefore, the body that has the highest speed is the solid cylinder and since time is the inverse of speed, this is the body that spends less time to reach the bottom, that is, it is the first to arrive
Answer:
yes
Explanation:
because no matter what voltage you connect it up to, the current always increases proportionally to the voltage.
this is because it follows ohm's law V = I X R.
(voltage = current X resistance)
so to calculate the resistance, change the formula to R = V / I giving you 60 ohm (resistor value)
the value of the resistor is always 60 ohm's, no matter which combination of voltage and current you used and measured, so it follows ohm's law, therefore being an ohmic resistor
