V = I x R and P = V x I
V = Voltage (can be either AC or DC)
I = Current in Amperes
R = Resistance in Ohms
P = Power in Watts
E is the energy in ergs,
m the mass of the
subatomic matter in
and c is the speed of
light in centimeters per
second: (c2 = 9 × 1020)
• Have an accurate stop watch and
measure the time taken by a rough
stone to reach the ground when
dropped from a height.
(eg. From the roof of a building)
• Distance in meters: d = g/2 x t2
where g = acceleration due to gravity
= 9.8 m/s2 usually, but needs to be
checked in your geographic area.
t = the time measured in seconds in
the above fashion.
• For many equations, the mathematics can be
programmed into an Online Calculator like this:
Speed of sound in feet per second through any given
temperature of air:
Take the square root of (273 + t), in which t is the air
temperature in Centigrade, multiply it by 1087, and divide
the result by 16.52.
When a jet breaks the sound barrier in air, not only is there a sonic boom, but
there is a visible cone of condensation from a dramatic change in pressure.
The body mass index (BMI), or Quetelet
index for adults, is a statistical measurement
which compares a fully grown adult person's
weight and height.
How They Did It
Instead of each member randomly choosing
numbers or relying on birthdays and
significant dates as they had done in the past,
this time they came up with what they
believed was an “unbeatable” formula.
This mathematical method was as follows:
All 49 numbers were written on pieces of paper and placed in
one box. Each syndicate member in turn then picked out six
numbers, until eight lines were filled, using 48 of the 49
numbers. The remaining number was then used to start a new
line by the next syndicate member, who picked from a second
box where the pieces of paper already drawn had been placed.
As a result each number appeared at least twice in the
syndicate’s 17 lines, with four numbers appearing three times.
Usual chances of winning a 6 from 49 lotto is about 1 in 14
million….. Seems they just got very lucky I guess ??
