Answer:
a =1.61 × 10⁻⁶ m/s²
Explanation:
given,
length of minute hand = 0.53 m
length of hour hand = 0.26 m
the time taken by the minute hand to complete one revolution is T=3600 s
the angular frequency is
the acceleration is
a =1.61 × 10⁻⁶ m/s²
Answer:
P = 2.91*10^{-24} kg m/s
size of atom hat lie in range of 1 to 5 Angstrom
Angstrom
Explanation:
A) MOMENTUM
p = mv
where m is mass of electron
so momentum p can be calculated as
p = 9.11*10^{-31} *3.2*10^{6}
P = 2.91*10^{-24} kg m/s
b) wavelength
where h is plank constant
so
c) size of atom hat lie in range of 1 to 5 Angstrom
d) from the information given in the question we have
we know that
[
]
Angstrom
