Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question ===> V = I · R .

Voltage = (current) x (resistance)

Voltage = (2 Ampere) x (8 Ω)

Voltage = 16 volts

If the period of a wave is 9.2 s, what is its frequency (in Hz)?

gogolik [260]

The period of the function is the inverse of the frequency:

⇒ (in other words) $period = \frac{1}{frequency}$

Since the period is 9.2s:

$Frequency = \frac{1}{period}=\frac{1}{9.2} =0.11_.Hz$

Answer: 0.11 Hz

Hope that helps!

A grandfather clock depends on the period of a pendulum to keep correct time. Suppose a grandfather clock is calibrated correctl

Setler [38]

Answer:

Slow

Explanation:

As we know that the time period of simple pendulum is given by

$T = 2\pi \sqrt{\frac{L}{g}}$

Where, l be the effective length of the pendulum and g be the acceleration due to gravity

As the length of the pendulum increase, then the tie period of the pendulum will also increase.

It means the clock run slow.

A soccer player kicks a soccer ball with a force of 1.8 N. If the mass of the ball is .43 kg. How fast will the ball accelerate?

Anna007 [38]

Answer:

$4.186 m/s^{2}$

Explanation:

Since Force, F= ma where m is the mass of the body and a is the acceleration of the object. Making acceleration the subject of the formula we obtain that

a=\frac {F}{m}

Substituting 1.8 N for F and 0.43 kg for m then we obtain that

$a=\frac {1.8}{0.43}=4.186046512 m/s^{2}\approx 4.186 m/s^{2}$
