Answer:
PE=0.92414J and KE=0.28175J
Explanation:
Gravitational potential energy=mass*gravity*height
PE=mgh
Data,
M=0.046kg
H=2.05m
g=9.8m/s^2
PE=0.046kg * 9.8m/s^2 * 2.05m
PE =0.92414J
KE=1/2mv^2
M=0.046kg
V=3.5m/s
KE=[(0.046kg)*(3.5m/s)^2]\2
KE=0.28175J

Answer:
The answer is B. composition
Explanation:
- The speed of a seismic wave is governed by three interrelated factors, viz. the composition of the rock, pressure, and temperature.
- Seismic waves travel at different speeds in different mediums.
- This property of the seismic waves tends it to change the speed where the concentration of minerals in the rocks varies.
- Other than that, the increasing temperature beneath the Earth's surface decreases the speed of the seismic waves, and the speed increases with increasing pressure as the waves go penetrating deep down into the Earth's interiors.
