True or false? Cells in the retina are photo-sensitive.

Answers

Answer:

True

Explanation:

Cells in the retina are indeed photosensitive. The retina is a layer of tissue located at the back of the eye that contains specialized cells called photoreceptors. Photoreceptors are responsible for detecting and responding to light stimuli, converting them into electrical signals that can be transmitted to the brain for visual processing. There are two main types of photoreceptor cells in the retina: rods and cones. Rod cells are highly sensitive to light and are responsible for vision in low-light conditions, while cone cells are responsible for color vision and visual acuity in bright light. Both rods and cones play crucial roles in the visual perception process and are essential for our ability to see.

super mario, spying a mystery block just ahead and wanting star power, takes a running leap towards the block, which is a distance of 8.2 m above mario's head. the acceleration due to gravity in the mushroom kingdom is roughly 1/5th of that on earth, gmk

Answers

The time taken by Super Mario  is 2.91 seconds to reach the mystery block.

To find the time it takes for Super Mario to reach the mystery block, we can use the kinematic equation:

∆y = v0t + (1/2)at2

Where ∆y is the change in a vertical position, v0 is the initial vertical velocity, a is the acceleration due to gravity, and t is the time.

Since the mystery block is 8.2 m above Mario's head, ∆y = 8.2 m. The initial vertical velocity, v0, is 0 m/s since Mario is starting from rest. The acceleration due to gravity in the Mushroom Kingdom, gmk, is 1/5th of that on Earth, so

a = (1/5)g = (1/5)(9.8 m/s2)

a = 1.96 m/s2.

Plugging these values into the equation, we get:

8.2 m = (0 m/s)t + (1/2)(1.96 m/s2)t2

Simplifying and rearranging, we get:

t2 = (8.2 m)/(0.98 m/s2)

Taking the square root of both sides, we get:

t = √((8.2 m)/(0.98 m/s2)) = 2.91 s

In two to four paragraphs, explain what happened musically as Britten introduced the orchestral instruments:

Answers


-- Unless I miss my guess, the phrase "In two to four paragraphs,
explain ..." sounds like you want somebody to write a nice essay
for you, which you will then write your name at the top of and hand
it in as your own work.  Are you sure you want to adopt this process
as a substitute for actually learning stuff ?
 
-- Sadly, you can probably forget about offering 5 points and getting
two to four paragraphs in return.

-- Another hunch of mine:  You're referring to the "Young Person's
Guide to the Orchestra" ... a fugue and variations based on the
Rondeau from Henry Purcell's incidental music to Aphra Behm's
Abdelazar, composed by Benjamin Britten in 1946 for elementary
music education.  The subject may not be too familiar to the people
who like to hang out here in the <Physics> category.  You might
stand a better chance if you post the question again in <Arts> or
even <Social Studies>.  I don't know of a way to 'move' a question
on Brainly, so you'll have to actually post it again ... and this time,
see if you can spare a few more points for an answer.

Answer:

Britten used a variety of instruments from different families and changed the traditional order. He started with the woodwinds, then strings, then brass, and percussion. He started with the highest pitched instruments in each of the families. This made the differences in the timbers of different sections of the orchestra more clear.

but he is right add more points next time you ask someone to do your work for you

Have researchers have now been able to cool substances to absolute zero

Answers

It's a law of nature, which I don't understand too well, that we can
cool things as close to Absolute Zero as we want to, but we can
never get all the way there. 

I think that individual atoms and molecules have been cooled in
the laboratory to within a few thousandths of a Celsius degree
of it ... actually not too shabby an accomplishment !
____________________________________

WOW !  I just went and searched online for more information
on this subject.  (You can't imagine what great stuff you can find
by doing that.  You ought to try it some time.)

The 1997 Nobel Prize in Physics was awarded to a team of three
physicists who invented a method of using lasers to slow down the
motion of atoms, and that's the same thing as cooling them.  They
were able to cool some atoms to a temperature of 240 millionths
of a degree above Absolute Zero !

The greatest obstacle to developing solar energy is _____. lack of sunlight at high latitudes lack of sunlight at night lack of mechanisms for storing solar energy large areas required to collect sufficient energy

Answers

The correct answer is option #4. The greatest obstacle to developing solar energy is large areas required to collect sufficient energy. Solar energy is the energy that is the sun is producing and being converted into thermal energy that can be used for everyone's daily lives.
