“Among countries that have the same steady state, the convergence hypothesis should hold:
poor countries should grow faster on average than rich countries”. Explain with graphs and
examples. (Romer Model)
why does preventing atp from binding to the enzyme inhibit the enzyme
Explain why an increase in saving in the Solow model has a level effect but not a growth
effect.
A) Discuss the steady state condition in the Solow model with population growth and no
technological progress.
B) In the Solow model with no population growth and no
technological progress, explain the golden rule level of consumption. Use a diagram to
discuss your answer.
C) When it would be possible to increase output per unit of labour
even at the steady state? Discuss.

A potential difference of 100 V is applied to the primary coil of a transformer. The current through the primary coil is 2.0 A. The potential difference across the secondary coil is 15 V
Calculate the current flowing through the secondary coil.
3. The position of a particle moving along the x-axis is given by x = 7t^2 + 2t^3, where x is in meters and t is in seconds. Determine the following, when t = 1.4 s:
