Answer: The recoil speed is - 8.9604.
m/s.
Explanation: According to the Third Law of Newton, every action has an oppsite and equal reaction, and the Second Law of Newton, Force=mass·acceleration. Acceleration is a variation in velocity by any given time, so Force = mass·velocity·time.
Combining the two laws, there is : m1·v1 = - m2·v2. This is the Law of Conservation of Momentum.
Substituting and calculating:
v2 = - (
) · v1
v2 = -
· 5.24.
v2 = - 8.9604.
The recoil speed of the thorium nucleus is - 8.9604.
m/s.
Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.

Answer with Explanation:
We are given that
Irradiation,G=6300
Surface A absorb.
a.


Where
=Boltzman's constant

Temperature of surface =577.4 K
b.



Hence, the emissivity of surface =0.89
