10 root 2 ie 14.14
For a sine wave, the RMS is the amplitude divided by square root of 2. The amplitude is 10 cm. in this case; so the exact value is 10 / root(2), or about 7.For a sine wave, the RMS is the amplitude divided by square root of 2.

10 is greater than square root 20 √20 = √(2 x 10) = √2 x √10 10 = √10 x √10 √10 > √2 → 10 > √20
Square root of 20 is 2*SQRT(5) or approx. 4.472 Square root of 40 is 2*SQRT(10) or approx. 6.325
10 squared is 100. 20 squared is 400. 225 is between 100 and 400. Its square root will be between 10 and 20.
sqrt(20)*sqrt(5) = sqrt(20*5) = sqrt(100) = ±10
