Velocity=3.4m/sec
Mass=30kg
so kinetic energy=1/2mv^2
=1/2×30×3.4×3.4
=15×3.4×3.4
=15×11.56
=173.4 kg m per second square
These are all caused by tectonic plate movements. Some areas of the globe are more susceptible to these disasters because they are on or near a fault line where the Earth’s tectonic plates rub against one another, slip beside and under each other, or collide. The places near fault lines are more likely to see earthquakes, tsunamis, and volcanic activity.
Answer:
Explanation:
Expression for time period of pendulum is given as follows
where l is length of pendulum and g is acceleration due to gravity .
Putting the given values for first place
Putting the values for second place
Dividing these two equation
T = 2.66455 s.
