Refer to the diagram shown below.
The given data is
mass, kg Coordinates. m
------------- -----------------
2 (0, 0)
2 (2, 0)
4 (2, 1)
Total mass, M = 2+2+4 = 8kg
Let (x,y) be the coordinates of M.
Then, taking moments about the origin, we obtain
8x = 2*0 + 2*2 + 4*2 = 12
x = 1.5 m
8y = 2*0 + 2*0 + 4*1 = 4
y = 0.5 m
Answer: (1.5, 0.5) m
Explanation:
1. Rt = 30/(1+3+6) = 30/10= 3 ohm
i = V/Rt = 15/3 = 5 A
2. Rt = 3+1+ (12×6)/(12+6)
= 4 + (72/18)
= 4+4 = 8 ohm
i = 12/(8+2)
= 12/10 = 1,2 A
A constellation is a group of stars in the sky.
If the group seems to form a pattern, or resemble anything,
it really has nothing to do with the constellation. The human
brain has evolved to seek and find patterns in what we see,
a habit of mind that turns out to have great survival value.
There's nothing "wrong" with seeing a pattern there. It's
a very natural, very human thing to do. But understand ...
the stars are not forming anything or doing anything. The
scorpion, the might hunter, the dog, the fish, the dragon,
the queen on her throne, the patterns ... are all in your mind.
Answer:
Centripetal acceleration
Explanation:
Centripetal force tends to keep an object moving within a circular or curved path to maintain its course while centripetal acceleration is what tends to accelerate the object towards the centre of the curve or circle
Solution :
Given :
The angle of the first maximum with the center is given by :
= 14.5°
The grating distance can be calculated as :
=
When the principal maxima yields at y = 0.488 m and the length from the wall 1.88 m. Thus the equation of the wavelength is :
, where n = 1
