The textbook Would most likely have more gravitational potential energy because it is heavier. Things that are heavier have a larger gravitational pull and are pulled to the earth faster
Explanation:
The speed of seismic waves is affected by the density of the underlying rock.
Seismic waves are elastic waves that transmits elastic energy from one point to the other.
These waves generally produced during an earthquake.
- The higher the density of rock bodies, the faster the wave travels.
- Rocks that are well packed with little to no void have a higher seismic velocity.
- Where density of rock is low, the speed is also low
Answer:
Explanation:
What would the answer be?
1) The metal which reduces the other compound is the one higher in the reactivity. So in this case it is
.
2) The substance which brings about reduction while itself getting oxidised (that is losing electrons) is called a reducing agent. Here, $\mathrm{Zn}$ is the reducing agent and reduces Cobalt Oxide to Cobalt while itself getting oxidised to Zinc oxide.
