Answer:
I=2.80 A
Explanation:
We Know that R =R₀(1+∝ ΔT)
R=R₀ (1+3.9*10⁻³ *(61-20))
R=R₀ (1.1599)
I=V/R=V/(R₀ (1.1599)
1.4 = V/(R₀ (1.1599) ∵ equation 1
We have to calculate I when T=-88°
R =R₀(1+∝ ΔT)
R=R₀ (1+3.9*10⁻³ *(-88-20))
R=R₀ (0.5788)
I=V/(R₀ (0.5788) ∵equation 2
Dividing equation 2 by equation 1
I = 2.80 A
Answer: No change in mass
Explanation:
Beta-emission: In this process, a neutron gets converted into a proton and an electron. The electron is referred to as a beta-particle. The beta particle released carries a charge of -1 unit and has negligible mass.
General representation of an element is given as:
Z= Atomic number
A = mass number
X = chemical symbol of element
