Answer:
adaptive optics.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.
A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies.
The technique called adaptive optics uses a high-speed computer to monitor atmospheric distortion and adjust the optics of a telescope to partially compensate for the seeing.
Basically, adaptive optics is used by astronomers to correct the distortions caused by the turbulence of the atmospheric conditions of the Earth in real-time, so as to have an image that is as sharp as anyone taken in space.
Answer:
$25
Explanation:
The computation of the intrinsic value of the stock is shown below:
As we know that
Intrinsic value or Price = Dividend ÷ (Cost of equity - growth rate)
where,
Cost of equity or ke is
= Risk free rate of return + beta × (Market rate of return - risk free rate of return)
= 6% + 0.75 × (14% - 6%)
= 12 %
So the intrinsic value is
= $1.50 ÷ (12% - 6%)
= $25
Answer: a) when the cross section is doubled the resultant resistence is a half. This means the thicker wire have half resistence than the thinner wire.
Explanation: In order to explain this behaviur we have to consider the expresion for the resistence which is given by:
where L and A are the length and the cross section for the wire, respectively.
From this expresssion we can conclude the above, this means
R=εo*L/A if A is now 2A we have
R' = εo*L/2*A= R/2
