Answer:

The appropriate response is "Optical printer ".

Explanation:

A photographic printer used mostly for optical aberrations, comprised simply of either a camera that captures the frame to expand, minimize, deform, respectively. through magnifying lenses.
A projector that always, as distinct from some kind of touch printer, transferred the image to something like the printing supply.

A student throws a rock horizontally off a 5.0 m tall building. The rock's initial speed is 6.0 m/s. How long will it take the r

Archy [21]

Answer:

The time taken by the rock to reach the ground is 0.569 seconds.

Explanation:

Given that,

A student throws a rock horizontally off a 5.0 m tall building, s = 5 m

The initial speed of the rock, u = 6 m/s

We need to find the time taken by the rock to reach the ground. Using second equation of motion to find it. We get :

$s=ut+\dfrac{1}{2}gt^2\\\\5=6t+\dfrac{1}{2}\times 9.8t^2\\\\t=0.569\ seconds$

So, the time taken by the rock to reach the ground is 0.569 seconds. Hence, this is the required solution.

PLEASE HELP. A substance decays according the the equation ae^-0.0025t, where t is in minutes. Find the half life of the substan

mojhsa [17]

First of all, that's not an equation. An equation needs an 'equals' sign ( = ),
so you need something like

   Amount present = a e^-0.0025t .

   'a' = amount present when t = 0 .

The half-life is the time it takes for the original amount to decay to half of it.

That's just 't' when       e^-0.0025t = 1/2

Take the natural log of each side: -0.0025t = ln(0.5)

Divide each side by -0.0025 : t = ln(0.5) / (-0.0025) =

   (-0.69315) / (-0.0025) =

   <em>t = 277.26 minutes</em>

( 4hrs 37min 15.5sec)

Rounded to nearest tenth: t = 277.3 minutes .
