A 9. 0 cm object is 3. 0 cm from a lens, which has a focal length of –12. 0 cm. What is the distance of the image from the lens? cm What is the height of the image? cm What type of lens created this image?.

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2

Calculate a pendulums frequency of oscillation (in hz) if the pendulum completes one cycle in 0.5s.
