The end or finish of an event or process.
Answer:
The fraction of kinetic energy to the total energy is
.
Explanation:
displacement is one third of the amplitude.
Let the amplitude is A.
x= A/3
The kinetic energy of the body executing SHM is

The total energy is

Divide (1) by (2)

Answer:

Explanation:
When the rock is immersed in unknown liquid the forces that act on it are shown as under
1) Tension T by the string
2) Weight W of the rock
3) Force of buoyancy due to displaced liquid B
For equilibrium we have 
=
When the rock is suspended in air for equilibrium we have

When the rock is suspended in water for equilibrium we have
+
=
Using the given values of tension and solving α,β,γ simultaneously for
we get

Solving for density of liquid we get


v = speed of car = 90 km/h
u = speed of truck = 50 km/h
d = initial separation distance = 100 m = 0.1 km
They meet at time t such that
vt = d + ut
t(v - u) = d
t = d/(v - u) = (0.1 km) / [(90 - 50) km/h] = 0.0025 hours
Answer:
x=0.8
Explanation:
Defining our values we have

Where
is the pressure of the super heated steam
is the Temperature of the super heated steam
and
is the pressure in an adiabatic process.
State 1

State 2

Note that here in state 2 the process is Reversible.
At the value where
we have

Through this values we can calculate the Fraction of steam,
