Q. What is the relationship between the sum of the interior angles of a triangle and the angles formed by a transversal cutting through two parallel lines? (2022)
A.They are equal
B.They are supplementary
C.They are complementary
D.They are unrelated
Solution
The sum of the interior angles of a triangle is 180 degrees, and the angles formed by a transversal cutting through two parallel lines are supplementary, meaning they add up to 180 degrees.
Q. What is the relationship between the wavelength and frequency of a wave?
A.Wavelength is directly proportional to frequency
B.Wavelength is inversely proportional to frequency
C.Wavelength is equal to frequency
D.Wavelength and frequency are unrelated
Solution
The relationship is given by the equation v = fλ, where v is the wave speed, f is the frequency, and λ is the wavelength. Thus, wavelength is inversely proportional to frequency.
Correct Answer: B — Wavelength is inversely proportional to frequency
Q. What is the relationship between voltage, current, and resistance according to Ohm's Law?
A.V = I * R
B.V = I / R
C.V = R / I
D.V = I + R
Solution
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with resistance (R) as the proportionality constant: V = I * R.
Q. What is the relationship between voltage, current, and resistance as described by Ohm's Law? (2021)
A.V = I + R
B.V = I * R
C.V = I / R
D.V = R / I
Solution
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the resistance (R) being the constant of proportionality. Therefore, V = I * R.
