A is directly proportional to the square of m a is 18.75 when m is 2.5 find a when m is 6?
a is directly proportional to the square of m So a = cm2 where c is the constant of proportionality. a = 2.5 when m = 18.75 2.5 = c*18.752 c = 2.5/18.752 When m = 6, a = (2.5/18.752) * 62 = 90/18.752 = 0.256
How do you find the value of a variable of a proportional ratio?
Cross multiply then solve for the variable.
What if the number is unknown to find square root square root?
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
How can you find the length of a segment joining two points on a coordinate grid without directly measuring it?
I think that you draw a square from that line, and find the area of that square.
Find the area of a square given that the length of each of its sides is .25 the value of its area?
0.0625 square units
How can you find effective length of a simple pendulum?
Measure the period, the period is directly proportional to the square root of the length.

If s is directly proportional to t and s equals 40 when t equals 15 find t when s equals 64?
s is directly proportional to t
Y is directly proportional to the square of x when x equals 4 y equals 25 Find an expression for the terms of x?
i think it would be like this: 4:25 :: 1:6.25
What is inverse square law of magnetism?
The force between two magnetic fields is directly proportional to the product of their magnitudes - and inversely proportional to the square of the distance between them. As an object gets further away, the influencing field decreases because of the increased area it affects. and the equation to find the force that acts between the two magntised objects is Force = (q1 x q2) / r^2 well the force is 'proportional' to that equation but i cant do a symbol for that. the force is measured in Newtons (N) and the r (radius) is measured in metres.

The temperature of an ideal gas is directly proportional to?
the equation for an ideal gas is pv / t = nr n * r is a constant for a closed system p pressure v volume t temperature in kelvin p1 v1 /t1 = p2 v2 /t2 if p1 = p2 v1/t1 = v2/t2 t2= v2/v1 *t1 directly proportional to the change in volume if v1 = v2 the same can be done and you will find that t is directly proportional to change in pressure. generally t is directly proportional to the product of pressure and volume. pv = nr t

What is the definition for direct proportional?
Direct proportional means as one value increases the other value increases as well. For example, if add mass into a plastic bag the bag will expand/stretch therefore if mass increase the streching will increase as well. Hope you find it helpful!
How do you find fourth proportional?
we can cross multiply the two equivalent equations and then find the fourth proportional
Why you use 0.707for rms values?
reciprocal of the square root of 2, converts from peak voltage to rms voltageAnother AnswerThis figure results when you work out how much work is done by one complete cycle of a.c. current. Since work is proportional to the square of a current, if you divide one complete cycle of a sine wave current into lots and lots of instantaneous values, square each of these values, find their average (mean) value, then find the square root of that value, you will have found the 'root-mean-square' of the current over a complete cycle. This value always works out to 0.707 x the peak or maximum value of the sine wave. For other waveforms, other r.m.s. values result.
