1: How many radians account for circumference of a circle ? 2: How many steradians account for circumference of a sphere? |
|
Answer» ong>Explanation: 1: So the circumference of a circle is 2 PI larger than its RADIUS. This means that in any circle, there are 2 PI radians. THEREFORE 360º = 2 PI radians. 2: A sphere subtends 4 pi SQUARE radians (steradians) about the origin. By ANALOGY, a circle subtends 2 pi radians about the origin. |

Answer» ong>Answer: 11th Physics Gravitation Acceleration due to Gravity the value of g at the surfa... PHYSICS avatar Asked on December 26, 2019 by Shaik Sethi the value of g at the surface of the earth is 9.8m/s . then the value of g at the PLACE 480KM above the surface of the earth will be NEARLY? (Radius of the earth is 6400km ) MEDIUM Help best friend Study later ANSWER M= mass of earth R= radius of earth =6400km=6.4×10 6 m g 1
= acceleration due to gravity on the surface of earth =9.8m/s 2
H= height above the surface of earth 480km=0.480×10 6 m g 2
= acceleration due to gravity above the surface of earth=? acceleration due to gravity on the surface is given g 1
= R 2
GM
----------------------------(1) acceleration due to gravity above the surface is given: g 2
= (R+h) 2
GM
------------------(2) g 1
g 2
= R 2

If two forces 15 Newton and 10 Newton acting perpendicular to each other find the resultant force . |
|
Answer» ONG>Explanation: If the forces act as in the opposite direction then, 1
−F 2
=10N...........1 And if they both act as a PERPENDICULAR then F 1 2
+F 2 2
=50N..............2 From EQUATION 1 we get F 1
=10+F 2
put this value in equation 2 then we get, (F 2
+10) 2 +F 2 2
=50 2
⇒F 2 2
+F 2 2
+100+2F 2
=2500 ⇒2F 2 2

(F 2
+40)−30(F 2

=30N Put this value in equation 1 then we get, F 1
=10+30=40N |

the magnification produced by a convex lens is -2. What is the image distance if the object is placed 10cm away to the left side of the lens |
|
Answer» ong>Answer: The magnification produced by a lens is equal to the RATIO of image distance to the object distance. Explanation: Object distance = x image distance = y so, m = y/x m = -2(according to the QUESTION) and image distance(x) = 10cm -2 = y/10 y = -20cm image distance in convex lens is positive maybe so is y = 20cm ? u CALCULATE that! :) HOPE it helps! :D plz mark me as brainliest! |

In the given circuit,find the power dissipated in 6 ohm ressistance. (do not spam either will get reported) ANS-9 watt (need full process) |
|
Answer» ong>Given: A circuit has been PROVIDED. The voltage source is 20 V To find: Power dissipated in the 6 ohm resistor. Concept: First find out the equivalent resistance of the circuit. In that equivalent circuit , find out the CURRENT . Then the power dissipated can be easily calculated. Power is the AMOUNT of energy dissipated by the resistance per unit time. Calculation: See the diagram for simplified circuit. The 5 ohm, 4 ohm and 6 ohm are in series. So net current will be : I = \dfrac{V}{(5 + 4 + 6)}I= (5+4+6) V
= > I = \dfrac{20}{(15)}=>I= (15) 20
= > I = \dfrac{4}{3} amp.=>I= 3 4
amp. Power dissipated in the 6 ohm resistor will be : P = {(I)}^{2} \times 6P=(I) 2 ×6 = > P = {( \dfrac{4}{3} )}^{2} \times 6=>P=( 3 4
) 2 ×6 = > P = \dfrac{16}{9} \times 6=>P= 9 16
×6 = > P = 10.66 \: watt=>P=10.66watt So final answer : \huge{ \green{ \sf{ \bold{ P = 10.66 \: watt}}}}P=10.66watt |
