Answer:
0.459 Tesla
Explanation:
Faraday's law:
Φ= NAB
V = N Δ (BA) /Δt
the change in BA
was: BA = 0 because initially B was zero.
V=IR
IR = N B A /Δt
q / Δt ×R = N B A / Δt
Or: B = q R / NA = 8.87 x 10^-3 × 45.0 / 1850×4.7 x 10^-4 =
= 0.459 Tesla

Refer to the diagram shown below.
The initial KE (kinetic energy) of the system is
KE₁ = (1/2)mu²
After an inelastic collision, the two masses stick together.
Conservation of momentum requires that
m*u = 2m*v
Therefore
v = u/2
The final KE is
KE₂ = (1/2)(2m)v²
= m(u/2)²
= (1/4)mu²
= (1/2) KE₁
The loss in KE is
KE₁ - KE₂ = (1/2) KE₁.
Conservation of energy requires that the loss in KE be accounted for as thermal energy.

Answer: 1/2
Here we can say that number of moles as well as pressure will remain same for the balloon
so here we can say by ideal gas equation
so here for constant pressure and constant number of moles we have
now by rearranging the equation we have
so final volume will be 0.89 liter
