Choose any THREE time periods and In each time period write a paragraph of ten lines based on your understanding of the differences of the time periods. Locate the time period in your context.
Explain the nature of hydraulic accumulators and bottle jacks’ application
and biases
The potassium atom has a work function of 2.3 eV. What is the maximum kinetic energy of the photoelectrons if 9.7 x 1014 Hz radiation is incident upon it?
calculate the uncertainty in the momentum of an electron lying with the state of uncertainty in its position of 5*10-10 m.
The pressure of an ideal gas is reduced by 50%, resulting in a decrease in temperature to 75% of the initial value. Calculate the ratio of the final to initial volumes of the gas
An object is 5kg and acceleration 30ms-1. After going 100 m the object starts to go at an acceleration of 30 ms-1. If after 100m we stop the force on object. How long will it go for?. Friction 10N.
y = 5 when x = 2 . Average rate of change of y w.r.t. x between x = 2 and x = 5 is 3 and between x = 5 and x = 8 is 4. What is the value of y when x = 8
In the lungs, the respiratory membrane separates tiny sacs of air (pressure 1.00x105Pa) from the blood in
the capillaries. These sacs are called alveoli. The average radius of the alveoli is 0.125 mm, and the air
inside contains 14% oxygen. Assuming that the air behaves as an ideal gas at 310K, calculate the number
of oxygen molecules in one of these sacs.
A bus moving in a straight line at a speed of 20 m/s begins to slow at a constant rate of 3.0 m/s2. Find how far it goes before stopping.
The pressure of an ideal gas is reduced by 50%, resulting in a decrease in temperature to 75% of the initial value. Calculate the ratio of the final to initial volumes of the gas.
