Answer:
Explanation:
Given
Temperature of gas at First stage
Pressure of gas at First stage
Volume Occupies
If the Pressure and Temperature at second stage is
Using ideal gas Equation
where P=Pressure
V=volume
R=Universal Gas constant
T=Temperature
n=no of moles
as n and R is constant therefore
thus
Explanation:
800 km per her because you have to divide 7200 by 9
Answer:
Explanation:
Geologists record the seismic waves and study how they travel through Earth. The speed of these seismic waves and the paths they take reveal how the planet is put together. Using data from seismic waves, geologists have learned that Earth's interior is made up of several layers.
Answer:
I) angle of reflection = 48 degrees
II) angle of deviation = 0
Explanation:
Given that the:
angle of incident = 48º.
According to law of reflection which state that the angle of incident is equal to the angle of reflection.
I.) Therefore,
angle of reflection = 48º.
II.) There can only be deviation if the mirror has a diffused surface. But for a smooth plane mirror, there can never be any deviation.
Therefore ,
The angle of deviation = 0
Given:
u(initial velocity):9.6 m/s
at the maximum height final velocity =0
The acceleration acting on the body is gravity as it is free falling object
=-9.8m/s^2
Now we know that
v^2-u^2 = 2as
Where v is the final velocity measured in m/s
u is the initial velocity which is measured in m/s
a is the acceleration measured in m/s^2
s is the distance traveled by the rock in this case it is considered as the height
Substituting these values we get
0-9.6= 2 x -9.8 x s
s= 0.49 m
Consider t as the time taken for the rock to travel
v=u+at
0=9.6 -9.8t
t=0.98sec
