C. The light bulb will be off
This is due to the reason that the wire doesn’t go back to the battery :)
Answer:
56.25 m
Explanation:
Cinematics describes the variables involved in movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time and displacement (or its scalar equivalent, distance).
We know the bobsled starts at 32m/s and ends at 22m/s with acceleration . The acceleration is negative because the bobsled is breaking of losing speed
The formula relating these three variables is
Solving for x
Answer:
The value of g is
Explanation:
From the question we are told that
The mass of the weight is
The spring constant
The second harmonic frequency is
The number of oscillation is
The time taken is
Generally the frequency is mathematically represented as
At second harmonic frequency the length of the string vibrating is equal to the wavelength of the wave generated
Noe from the question the vibrating string is just half of the length of the main string so
Let assume the length of the main string is
So
The velocity of the vibrating string is mathematically represented as
Where T is the tension on the string which can be mathematically represented as
So
Then
=>
=>
=>
substituting values
Generally the period of oscillation is mathematically represented as
=>
The period can be mathematically evaluated as
substituting values
Therefore
so
substituting for L
=>
A copper wire of diameter 3.256mm carries a current of 6.25mA. the potential difference is mathematically given as
V=2.0657*10^{-4}
<h3>What is the potential difference across a 200m length of the wire?</h3>
Generally, the equation for is mathematically given as
R=Pl/A
Therefore
R=1.72*10^{-8}*2.00/\pi*(1.628)^2*10^{-6}
R=1.652*10^{-2}
In conclusion,
V=IR
V=12.5*10^{-3}*1.652*10^{-2}
V=2.0657*10^{-4}

The splitting of light occurs because of the shape of the prism and the different interactions of the components of the white light with the glass. ... This splits the white light into its component colours before it reemerges from the rain drop so a rainbow is produced.
