That looks like something I have right down
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
![\frac{1}{q} = \frac{1}{f} - \frac{1}{p}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bq%7D%20%3D%20%5Cfrac%7B1%7D%7Bf%7D%20-%20%5Cfrac%7B1%7D%7Bp%7D)
we calculate
![\frac{1}{q} = - \frac{1}{12} - \frac{1}{29}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bq%7D%20%3D%20-%20%5Cfrac%7B1%7D%7B12%7D%20-%20%5Cfrac%7B1%7D%7B29%7D)
= - 0.1178
q = -8.488 cm
the negative sign indicates that the image is virtual
B) the magnification is given
![m = \frac{h'}{h} = - \frac{q}{p}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7Bh%27%7D%7Bh%7D%20%3D%20-%20%5Cfrac%7Bq%7D%7Bp%7D)
we substitute
m =
m = 0.29
the positive sign indicates that the image is right
W=Fd
W is work
F is force in newtons
D is displacement in meters
W= 25 x 3
W= 75Nm
Answer:
1.The Washington Monument is 555 feet tall.A.If 1 meter = 3.28 feet, what is the height of the Washington Monument in meters? 1,820.4 mB.A worker assigned to the restoration of the Washington Monument is checking the condition of the stone at the very top of the monument. A nickel with a mass of 0.005 kg is in her shirt pocket. What is the gravitational potential energy (GPE) of the nickel at the top of the monument?GPE = mghGPE = (0.005 kg)(0 m/s2)(1,820.4 m)GPE = 0 JC.What is the kinetic energy (KE) of the nickel in her shirt pocket at the top of the monument?KE = 1/2mv2KE = (0.5)(0.005 kg)(0 m/s)2KE = 0 JD.If the nickel accidentally falls out of her pocket, what will happen to the gravitational potential energy (GPE) of the nickel as it falls to the ground?The GPE will decrease because the height is decreasing.E.If the nickel accidentally falls out of her pocket, what will happen to the kinetic energy (KE) of the nickel as it falls to the ground
