A Newtonian reflector needs no secondary mirrors?
It is not essential to have a secondary mirror on a Newtonian telescope, but the reason there is one is for practicality. If you mounted an eyepiece at the focus of the primary mirror, your head would be directly in the light path, blocking much of the light from entering the tube. The same reason applies to cameras, but with modern CCD cameras being circular and small, it is possible to mount one at the focus of the primary mirror. Indeed, doing this may block less light than a secondary mirror would, certainly in the case of a large aperture instrument (for example 300mm and above.)
Is squash a tap root?
Further, the taproot of squash and other vine crops must not be damaged in Long taproots and branching surface roots enable squash plants to access soil they are over-large, with large seeds, hard skins, and fibrous or watery flesh.
What are the three categories of explosives?
Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.

How current transformer measure current?
A current transformer doesn't 'measure current'. It merely reduces a large current flowing through its primary to a smaller current which can be read by an ammeter connected to its secondary. At the same time, it electrically isolates the secondary circuit from the primary circuit, which is essential if the primary circuit is part of a high-voltage system.
Why can a secondary source more helpful than a primary source?
They summarize conclusions about primary sources.
Which side is the primary side of a coil?
Both of the small posts (pos & neg) are primaries. The large connection is the secondary.
How do you calculate the percentage biomass passed on from 1 from producers to primary consumers 2 from primary to secondary consumers 3 from secondary consumers to carnivores?
e.g. ORGANISM BIOMASS Grass 1000 Herbivores 300 Small Carnivores 28 Large Carnivores 6 1) from producer to primary = (300/1000)x100 2) from primary to secondary = (28/300)x100 3) from secondary to carnivores = (6/28)x100 Hope this helps :)
Why secondary coil of ct is short?
A CT attempts to push a specific ratio of primary current through the secondary. If the secondary is open circuited, the resistance across the secondary will be very large. Following Ohm's law, V = I*R, so the secondary voltage will become very large, and will arc across the open, or damage the CT, or both.
Do most conifers exhibit excurrent branching or deliquescent branching?
They exhibit excurrent branching because their terminal buds grow tall and straight with branches coming from a large central shaft.
What roots does a dandelion have?
The dandelion is has a taproot system, which consists of one large primary root, and several small secondary roots. This is why it is so difficult to pull out dandelions completely, without breaking the stem and leaving the root in the ground.
Is aluminum a secondary or primary source of light?
Aluminium is not normally a source of light. I suppose if you made a large mirror out of it you could turn that into a secondary source.
What is the small tube branching of the large intestine?
Ileocecal Valve
Primary and secondary social group?
Primary social groups are small, intimate, and long-lasting groups where individuals have regular and direct interactions, such as families and close friends. Secondary social groups are larger, more formal, and based on shared interests or activities, like clubs, teams, or professional organizations. Primary groups typically provide emotional support, while secondary groups offer opportunities for networking and achieving common goals.
Is hard disk a secondary device?
primary and secondary storage may also refer specifically to the components inside the computer. In this case, primary storage typically refers to random access memory (RAM), while secondary storage refers to the computer's internal hard drive.
Why hard disk is called secondary memory?
Since primary memory is not sufficient to store large volumes of data, externally some memory is added.this is known as hard disk which is also known as secondary memory
