E = mc^2
m = e/c^2
m = 2.7*10^16/(300000^2)
m = 300000
Answer:
Φ = 5.589×10⁻⁵ Wb
Explanation:
The inductance of a coil is given as
L = e/(di/dt) ..................... Equation 1
Where L = inductance of the coil, e = induced e.m.f, di/dt = rate of change of current in the coil.
Also,
The inductance of each turn of the coil when a magnetic field is step up in the coil is
L = NΦ/i ................. Equation 2
Where N = number of turns, Φ = magnetic field, i = current.
equating equation 1 and equation 2
e/(di/dt) = NΦ/i
making Φ the subject of the equation,
Φ = (e×i)/N.(di/dt) .................. Equation 3
Given: e = 28.0 mV = 0.028 V, N = 501 turns, di/dt = 12.0 A/s, i = 4.00 a
Substitute into equation 3,
Φ = (0.028×4)/(12×501)
Φ = 0.112/2004
Φ = 5.589×10⁻⁵ Weber
Φ = 5.589×10⁻⁵ Wb
Explanation:
The acceleration g varies by about 1/2 of 1 percent with position on Earth's surface, from about 9.78 metres per second per second at the Equator to approximately 9.83 metres per second per second at the poles.
Answer:
The acceleration of the object is -69.78 m/s²
Explanation:
Given;
postion of the particle:
The velocity of the particle is calculated as the change in the position of the particle with time;
Acceleration is the change in velocity with time;
Answer: An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.
Explanation: To find the answer, we need to know about the Ammeter and Voltmeter.
<h3>What is an ammeter?</h3>
- An ammeter is a device, that can be used to measure the electric current flows through a circuit in amperes.
- An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance when it is connected in series to measure the current.
<h3>What is voltmeter?</h3>
- A voltmeter is a device, that can be used to measure the electric potential difference generated between the terminals of an electric circuit in volts.
- An ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter, when it is connected in parallel to measure the voltage.
Thus, we can conclude that, an ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.
