Question

i need the answers to all 10 questions please.

Questions parabolic reflectors only. This statement is: (1) All satellites use correct or incorrect. [2] The principal axis is drawn: outward from the center of the surface, so that surface is symmetrical about the axis, so that all-reflection occur along the entire axis, outward from end of the surface. [3] The parabolic reflector focuses on: a parabolic shape, a spherical shape, a single point a small line. [4] The spherical reflector focuses on: a parabolic shape, a spherical shape, a single ponyt, a small line. [5] The transmitter must be placed: anywhere along principal axis, at center of dish, at edge of dish, at the focus. [6] The receiver must be placed: anywhere along principal axis, at center of dish, at edge of dish, at the focus. [7] The satellite dish whose receiver is moved, not the dish, is: spherical reflector or parabolic reflector. [8] All satellites use radio waves only. This statement is: correct or incorrect. [9] The Geostationary Operational Environmental Satellite uses which EM wave to study and track storm systems like hurricanes? radio, UV, infrared, x-rays. [10] Small dishes are connected in an array instead of using one large dish because of all of the following except: less expensive to operate and maintain, lighter to carry, ability to operate when one malfunctions, more effective in receiving simultaneous transmissions.

Answer 1

Solution :- - at almost every wave 1 Yes, it is correct. They typically comprises of a single parabolic reflector that is similar to a satellite antenna which has a microwave receiver situated at its focus. A parabolic reflector collects ene energy length even from distant sources ie. mostly sunlight or even starlight: 31 The principal axis is always drawn perpendicular to the surface · It is positioned at the center of mass for the surface | body. Hence, it is the plane of symmetry for that surface 3) The parabolic reflector focuses on a small line Incoming signals are focused at a particular point while radiating from this point, all the ray and will provide required energy or radiation Y) The spherical reflector focuses on a single point. When light rays fall on a spherical reflector, they diverge at a particular point g The transmitter must be placed at focus, C) to gain maximum intensity , the receiver must be placed at the focus of the dish. Because parallel are directed towards the focus. signals will in a propagate aparallel either converge or wares

8 7) Receiver of parabolic reflectors has to move to gain transmission, 8) Incorrect, they use microwave too. Infrared, as they help us to see the temp. gradient , hence, wind pressure and stooms. less expensive to op erate and and maintain > 10) operate
