Answer:
The Energy possessed by a body by virtue of its position or state is called Potential energy.
Mathematically potential energy can be written as,
Potential energy = mgh
Where 'm' represents mass of the body, 'g' represents gravity of the earth and 'h' represents height of body. Potential energy depends on the height, higher the hight from the surface of the earth, maximum will be the potential energy.
Answer:
dart's speed is 11.77 m/s
Explanation:
given data
mass of the gun m = 355 gram = 0.355 kg
height = 18.3 centimeters = 0.183 m
dart = 57.0 gram = 0.057 kg
to find out
dart's speed
solution
we apply here law of conservation of energy that is express as
mgh = 0.5 × m × v² ...........1
so speed of gun will be here as
V = 
..................2
V = 
V = 1.89 m/s
and
now we find speed of dart by use law of conservation of momentum that is
M×V = m×v ...............3
so speed of the dart is
v = 
v = 
v = 11.77 m/s
so dart's speed is 11.77 m/s
Answer: In or discussion of earthquake we want to answer the following questions side has moved to the left, we say that the fault is a left-lateral strike-slip fault. Surface waves behave like S-waves in that they cause up and down and side. Aftershocks are particularly dangerous because that can cause further .
