Energy Transformation for a Pendulum
Because there are no external forces doing work and the total mechanical energy of the pendulum bob is conserved. The conservation of mechanical energy is described in the animation below. Assume the KE and PE bars of the bar chart and their sum is a constant value.
Why is heavy water used as a moderator? Heavy water is a type of water highly enriched in the hydrogen isotope deuterium. We can conclude the neutron interactions with billiard

Q. The work function of a metal surface is 1.8 eV. Compute the threshold wavelength. Work function W = hγ o = h C / λ 0 λ 0 = h C / W = 6.626 X 10 -34 X 3 X 10 8
#quest. Imagine a small observer is positioned in front of the cork in your picture above. As the cork approaches, the observer measures the wavelength of the waves passing by. How
Q. What are the limitations of electron microscope? An electron microscope is operated merely in high vacuum. This prohibits the utilize of the microscope to study living organ
Balanced and Unbalanced Forces:- Newton's first law of motion states that "an object at rest stays at rest and an object in motion stays in motion with the similar speed and in
IMPULSE: When a force acts on a body for a very short time, the product of the force and the time for which the force acts, is called the impulse or impulse of force".
A 77.0-kg woman is walking 0.10 m/s east in the gym. A man throws a 15.0-kg ball south and accidentally hits the woman. The woman and the ball move together with a velocity
