A small object is 25.0 cm from a diverging lens as shown in the
figure. A converging lens with a focal length of 12.0 cm is
30.0 cm to the right of the diverging lens. The two-lens system
forms a real inverted image 17.0 cm to the right of the
converging lens. What is the focal length of the diverging lens?
What is the total magnification of the final image?
What role does using the right evidence play in being a
professional nurse?
What role does understanding plagiarism and academic integrity
play in being a professional nurse?
5. What fraction of rest mass energy is converted from potential
energy to kinetic energy when a particle comes from infinity to the
event horizon of a black hole?
What is the kinetic molecular theory? What role does attraction
play in this? please appreciate typewriting when responding to this
question.i have a poor vision I cant read handwriting
What role does knowledge play in being a good person? Answer
this question from the perspectives of Augustine, Nietzsche and
Aristotle. Be sure to justify the claims with arguments.
An object with mass m = 0.6 kg is dropped from the top
of the building and falls 21 m down in front of the
cafe.
1.1 Calculate the speed of the object as it
hits the ground and calculate the time for the fall. Neglect in
this question the air resistance.
In a more accurate calculation we need to take air resistance
into account. In a wind tunnel the air resistance of the object has
been measured giving rise...

Answer the following questions:
1. An object with mass M and velocity V has kinetic energy K=
1/2MV^2. If the velocity of the object is reduced to 1/5V, then its
new kinetic energy is: a)1/5K b) 5K c)1/25K d) 25K
2. Velocity is a vector, therefore it has magnitude and
direction. In a circular motion, the change in magnitude and
direction of velocity respectively produce: a) centripetal
acceleration and tangential acceleration b) tangential acceleration
and centripetal acceleration c) tangential force...
