We can solve both parts of the problem by using the lens equation:
\frac{1}{f} =  \frac{1}{d_o}+ \frac{1}{d_i}
where
f is the focal length
d_o is the distance of the object from the lens
d_i is the distance of the image from the lens

Let's also keep in mind that for a converging lens, the focal length is taken as positive, so f=+19.0 cm.

(a) In this case, d_o = 41 cm. So, the lens equation becomes
\frac{1}{d_i}= \frac{1}{f}- \frac{1}{d_o}= \frac{1}{19 cm}- \frac{1}{41 cm} =0.028 cm^{-1}
And so the distance of the image from the lens is
d_i =  \frac{1}{0.028 cm^{-1}} =+35.4 cm
where the positive sign means the image is real, i.e. is located behind the lens (opposite side of the real object)

(b) In this case, d_o = 14 cm. So, the lens equation becomes
\frac{1}{d_i}= \frac{1}{f}- \frac{1}{d_o}= \frac{1}{19 cm}- \frac{1}{14 cm} =-0.019 cm^{-1}
And so the distance of the image from the lens is
d_i = \frac{1}{-0.019 cm^{-1}} =-53.2 cm
where the negative sign means the image is virtual, i.e. is located in front of the lens (i.e. on the same side of the real object)

Two lightbulbs both operate on 120V . One has a power of 25W and the other 100W. (ii) Which lightbulb carries more current? Choo
Vikki [24]

The lightbulb that carries more current will be the 25W bulb.

<h3>How to explain the information?</h3>

It should be noted that an electric current simply means the stream of charged particles that move through an electrical conductor or space.

In this case, it should be noted that the power is the same for both bulbs. Therefore, the 25W bulb will have the higher resistance so that it will have lower power.

Therefore, the lightbulb that carries more current will be the 25W bulb.

A box slides down a 31° ramp with an acceleration of 0.99 m/s2. Determine the coefficient of kinetic friction between the box an
tino4ka555 [31]

Answer:\mu=0.48

Explanation:

Given

inclination \theta =31^{\circ}

Acceleration of object=0.99 m/s^2

Now using FBD

mg\sin \theta -f_r=ma

mg\sin \theta -\mu mg\cos \theta =ma

a=g\sin \theta -\mu g\cos \theta

0.99=5.04-\mu 8.4

\mu 8.4=4.057

\mu =0.48
