Answer:
The period of that same pendulum on the moon is 12.0 seconds.
Explanation:
To determine the period of that same pendulum on the moon,
First, we will determine the value of g (which is a measure of the strength of Earth's gravity) on the Moon. Let the value of g on the Moon be .
From the question, the strength of earth’s gravity is only 1/6th of the normal value. The normal value of g is 9.8 m/s²
∴ =
= 1.63 m/s²
From the question, T=2π√L/g
We can write that,
.......... (1)
Where is the period of the pendulum on Earth and is the measure of the strength of Earth's gravity
and
.......... (2)
Where is the period of the pendulum on Moon and is the measure of the strength of Earth's gravity on the Moon.
Since we are to determine the period of the same pendulum on the moon, then, and are constants.
Dividing equation (1) by (2), we get
From the question,
= 9.8 m/s²
= 1.63 m/s²
= ??
From,
∴
Hence, the period of that same pendulum on the moon is 12.0 seconds.
Answer:
An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout. A device designed to open or close a circuit under controlled conditions is called a switch.
In other words, a closed circuit has a complete path for current to flow, whereas an open circuit doesn't, which means that it's not functional. open circuit is a circuit which is not completed. Any circuit which is not complete is considered an open circuit.

We have a problem with three different state of the ratio of flow velocity to speed of sound.
That is,
a) Mach number to evaluate is 0.2, that mean we have a subsonic state.
The equation here for lift coefficient is,
where should be expressed in Rad.
So replacing in equation for subsonic state,
b) In this situation we have a transonic state, so we need to use the Prandtl-Glauert rule,
c) For this case we have a supersonic state, so we use that equation,
The speed of the object v is 16 m/s.
The mass of the object moving on the horizontal surface is m.
The speed of the object is v m/s.
The coefficient of friction, μ = 0.40
The acceleration due to gravity, g = 10 m/s²
So, the initial velocity is v m/s and the final velocity is 0 m/s.
The total distance traveled by the object is 32 meters.
The formula for force is:
F = ma
Now,
ma = - μmg
a = - μg
a = - 0.40 × 10 = - 4 m/s²
The distance, s = 32 meters
Using the equation of motion,
v² = u² + 2as
0 = v² + 2( - 4 )( 32 )
0 = u² - 256
u² = 256
u = √256 = 16 m/s
Hence, the value of the speed v is 16 m/s.
