Answer:
A) q = -8.488 cm
, B) m = 0.29
Explanation:
A) For this exercise in geometric optics, we will use the equation of the constructor
where p and q are the distance to the object and image, respectively and f is the focal length
in our case the distance the object is p = 29 cm the focal length of a diverging lens is negative and indicates that it is f = - 12 cm
we calculate
= - 0.1178
q = -8.488 cm
the negative sign indicates that the image is virtual
B) the magnification is given
we substitute
m =
m = 0.29
the positive sign indicates that the image is right
<span>The reaction force would be the exact opposite of the action. In this case, choice (c) would be the most correct. If the action is the ball pushing the glove, the reaction would then be the glove pushing back on the ball.</span>
So first we have to solve for the total momentum of the entire system. We can do this by solving momentum for the first train. The equation for momentum is p=mv, where "p" is momentum.
Total momentum is
When the first train comes to a complete stop, it is an elastic collision. We can use conservation of momentum to solve for the velocity of the second train.
If they stick completely, then it is an inelastic collision. Here we have to combine the mass of the two trains and solve for the velocity.
Finally, if the train is 20m/s then what is the velocity of the first train. Just like before, we can solve using conservation of momentum.
