Answer:
a) m = 993 g
b) E = 6.50 × 10¹⁴ J
Explanation:
atomic mass of hydrogen = 1.00794
4 hydrogen atom will make a helium atom = 4 × 1.00794 = 4.03176
we know atomic mass of helium = 4.002602
difference in the atomic mass of helium = 4.03176-4.002602 = 0.029158
fraction of mass lost = = 0.00723
loss of mass for 1000 g = 1000 × 0.00723 = 7.23
a) mass of helium produced = 1000-7.23 = 993 g (approx.)
b) energy released in the process
E = m c²
E = 0.00723 × (3× 10⁸)²
E = 6.50 × 10¹⁴ J
Answer:
Frequency is
Explanation:
Distance between source 1 from the receiver ,
Distance between source 2 from the receiver ,
Now ,
Path difference ,
We know, for constructive interference path difference should be integral multiple of wavelength .
Therefore,
It is given that n = 1,
Therefore,
Frequency can be found by ,
Hence, this is the required solution.
