Consider a simple pendulum with a period
lisabon 2012 [21]

Answer:

1. The length is 8.35m

2. The period on the moon is 14.05 secs

Explanation:

1. Data obtained from the question. This includes the following:

Period (T) = 5.8 secs

Acceleration due to gravity (g) = 9.8 m/s2

Length (L) =...?

The length can be obtained by using the formula given below:

T = 2π√(L/g)

5.8 = 2π√(L/9.8)

Take the square of both side

(5.8)^2 = 4π^2 x L/ 9.8

Cross multiply

4π^2 x L = (5.8)^2 x 9.8

Divide both side by 4π^2

L = (5.8)^2 x 9.8 / 4π^2

L= 8.35 m

2. Data obtained from the question. This includes the following:

Acceleration due to gravity (g) = 1.67 m/s2

Length (L) = 8.35m (the length remains the same)

Period (T) =?

The period can be obtained as follow:

T = 2π√(L/g)

T = 2π√(8.35/1.67)

T = 14.05 secs

Therefore, the period on the moon is 14.05 secs

How does electroscope detect type of charge ?
Shtirlitz [24]

Answer:

An electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it. The amount of charge on an object is proportional to its voltage.

Can anyone help?6th question.free brainliest answer...
DIA [1.3K]

There's a crest and a trough in each complete wave.  So the question is describing 10 complete waves.

After that, the question becomes somewhat murky.  It goes on to say "its time period is 0.2 seconds".  

-- The "time period" of a wave is usually defined as the time for <u><em>one</em></u> complete wave.  If that's what the phrase means, then ...

Frequency = ( 1/0.2sec )

<em>Frequency = 5 Hz.</em>

<em>= = = = = = = = = =</em>

<u>BUT</u> ... Is the question awkwardly trying to tell us that the <u><em>10 waves</em></u> take 0.2 seconds ?  If that's what it's saying, then ...

Frequency = (10) / (0.2 sec)

<em>Frequency = 50 Hz .</em>
