Ohm's Law
Explanation:
The relationship:
where V represents the voltage across a resistor of resistance "R" through which a current (I) flows,
is known as Ohm's Law in honor of Georg Ohm, who discover this proportionality.
Answer:
Law of refraction
Explanation:
An experiment to analyze the refraction of light in water can easily be performed with a laser pointer and protractor.
We throw the fishing rod line into the water, place the protractor at the point where the line touches the water and use the direction of the line for the direction of the laser pointer (on), the laser is visible by the reflection on the particles in the air.
The vertical line is called Normal and all angles must be measured with respect to this reference in optics.
Having these angles and the refractive index of water we can use the law of refraction
n₁ sin θ₁ = n₂ sin θ₂
θ₂ =
we can repeat several times to analyze several different input points (different angles) and to decrease the errors in the measurements.
the refractive index of air is n1 = 1 and n2= 1.33 (water)
Answer:
P-value of the test statistic is 2.499
Explanation:
given data:
size sample is 24
sample mean is 414 gm
standard deviation is 15
Null hypotheis is
level of significance is 0.01
from test statics
degree od freedom is = n -1
df = 24 -1 = 13
t = -1.959
from t table critical value of t at 0.1 significane level and 23 degree of freedom is 2.499
