You would find the potential difference aka voltage, but more specifically it would be just the voltage that the resistor uses and not the whole circuit.
But if you want the voltage value it’s V=IR so whatever the current is multiply it by the 45 ohm resistor value
Answer:
Length, l = 0.866 meters
Explanation:
Given that,
Frequency of sound, f = 99 Hz
Speed of sound in air, v = 343 m/s
To find,
The length of a wind instrument.
Solution,
The standing wave will gets formed in wind instrument. For the closed tube, the closed tube the frequency is given by :

Where
l is the length of the instrument


l = 0.866 meters
So, the length of a wind instrument is 0.866 meters. Hence, this is the required solution.
Answer:
because the book's is covered by papers
The reason is because the force due to the acceleration from gravity is constant. It's the same as the typical "dropping a bowling ball and feather (with no air resistance) at the same time". Gravity acts on all object with the same acceleration regardless of physical properties.
When block is pushed upwards along the inclined plane
the net force applied on the block will be given as

here we know that
m = 75 kg


now plug in all values into this


now for finding the power is given as
