The velocity of a falling object. In physics, down is regarded as a negative direction.
<h3><u>Answer;</u></h3>
<em>The voltage is zero</em>
<h3><u>Explanation;</u></h3>
- <em><u>Voltage is the potential difference between two points in a circuit or the electromotive force in a given circuit and is expressed in volts (V). </u></em>
- Voltage is measured by a device called voltmeter that is always connected in parallel with the current source.
- <em><u>When voltage is measured between two points on a wire in a circuit with zero or no resistance in between the two points then the voltage will be zero</u></em><em>. </em>From the ohm's Law, voltage is given the product of resistance and current and thus if the resistance is zero then the voltage will be zero.
Explanation:
that the people closer too the head of the table will feel more vibrations than the people at the end of the table. since the vibrations will slow down as they travel farther down the table
Hope this helps!!
Answer:
1.) Micrometres screw gauge
2.) Tape rule.
Explanation:
Given that the diameter and the length of a thin wire, approximately 1m in length, are measured as accurately as possible.
what are the best instruments to use ?
To measure the diameter of a thin wire, the best instrument to use is known as micrometres screw gauge.
And to measure the length of a thin wire up to 1 m, the measuring device can be tape rule or long metre rule.
