Which of the following means that an image is located behind a lens? A. +di B. -di C. -do D. +do
STatiana [176]
For a lens, the following sign convention is generally used:

- f (the focal length) is positive for a converging lens and negative for a diverging lens
- d_o (the distance of the object from the lens) is positive if the object is in front of the lens and negative if it is behind the lens
- d_i (distance of the image from the lens) is positive if the image is behind the lens (real image) and negative if the image is in front of the lens (virtual image)

Therefore, the correct option is 
<span>A. +di
</span>which mens that the image is real and located behind the lens.

The speed of light is 3.0 x 108 m/s. How far does light travel in one day? Remember that you should first convert the day into s
Anna35 [415]

Answer:

2.59\times 10^{13}\ m

Explanation:

The speed of light is 3.0 x 10⁸ m/s

We need to find the distance traveled by it in one day.

1 day = 24 hours

1 day = 24 × 3600 seconds

= 86400 s

Now, using the formula of speed to find the distance covered as follows :

d=v\times t

Putting all the values, we get :

d=3\times 10^8\ m/s\times 86400\ s\\\\d=2.59\times 10^{13}\ m

Hence, light will cover 2.59\times 10^{13}\ m of distance in one day.

In figure 16-2 is the temperature of the material within the cylinder greatest during the intake stroke, compression stroke, pow
erastovalidia [21]
Technically, we have no way of knowing that without seeing Figure 16-2.
So the question should be reported for incomplete content.  But I'm
going to take a wild stab at it anyway.

There's so much discussion of 'cylinder' and 'strokes' in the question,
I have a hunch that it's talking about the guts of a 4-stroke internal
combustion gasoline engine. 

If I'm right, then the temperature of the material within the cylinder is
greatest right after the spark ignites it.  At that instant, the material burns, 
explodes, expands violently, and drives the piston down with its stiff shot
of pressure.

This is obviously happening because of the great, sudden increase in
temperature when the material ignites and explodes.

It hits the piston with pressure, which leads directly to the power stroke.
