Answer:
mass of one atom is measured in the unit of 1 amu
Explanation:
As we know that the mass of one atom is very small and it is of order of
here we know that 1 amu is defined as 1/12 part of mass of 1 atom of C-12 isotope
so here we will have
so here we can say that mass of one atom is measured in the unit of 1 amu
Answer:
a) 107.1875 Hz
b) 214.375 Hz
c) 321.5625 Hz
Explanation:
L = length of the open organ pipe = 1.6 m
v = speed of sound = 343 m/s
f = fundamental frequency
fundamental frequency is given as
inserting the values
Hz
b)
first overtone is given as
f' = 2f
f' = 2 (107.1875)
f' = 214.375 Hz
c)
first overtone is given as
f'' = 3f
f'' = 3 (107.1875)
f'' = 321.5625 Hz
Answer:
<em>B. 68.6m</em>
Explanation:
<u>Free Fall Motion </u>
When a body is left to move in the air with no friction, the motion is ruled only by the force of gravity. The vertical distance a body travels in the air after a time t is .
We know the egg takes 3.74 seconds to reach the ground. The height it was launched from is
The closest correct option is
B. 68.6m
