If the temperature is high there is less water because it evaporates if it is cloudy it is more because it doesn't evaporate
Answer:
Explanation:
Let the critical angle be C .
sinC = 1 / μ where μ is index of refraction .
sinC = 1 /1.2
= .833
C = 56°
Then angle of refraction r = 90 - 56 = 34 ( see the image in attached file )
sin i / sinr = 1.2 , i is angle of incidence
sini = 1.2 x sinr = 1.2 x sin 34 = .67
i = 42°.
Answer:
90 ohms
Explanation:
1/r = 1/180 + 1/180
1/r= 2/180
take the reciprocal of 2/180 which is 180/2 and its 90 ohms
Answer:
(2/3) times height collision occur
Explanation:
for ball A
from the kinematic equation
the distance of ball A is

= velocity ( time ) = distance
since ball is at height, the above equation changes as

for ball B

the condition of collision is
xA = xB
(given)
from the kinematic equation
the speed of the ball A is

since initial speed of the ball A is zero
, so

the speed of the ball B is

since




since 






so, (2/3) times height collision occur
