Answer:
834 milli-volts
Explanation:
Data provided in the question:
Current = 139 milliamps = 139 × 10⁻³ A
resistance = 6 ohms
Now,
The relation between the current , resistance and voltage is given as:
Voltage = Current × Resistance
on substituting the respective values, we get
Voltage = 139 × 10⁻³ × 6
or
Voltage = 834 milli-volts
Answer: The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero. there is more than one force acting on an object, then F is the net force. If two people pull on an object with equal forces in opposite directions, then the net force is zero and the acceleration is zero

Answer:
A- series B- parallel
Explanation:
In order to measure current in a circuit, the multi-meter needs to be placed in series with the circuit while when measuring voltage, the multi-meter needs to be placed in parallel with the circuit.
It should be however noted that the same current flows in a series connected circuit and same voltage flows through loads connected in parallel. The ammeter is placed in series with the load to ensure that same value of currents is flowing in both the ammeter and loads(since same current flows in series connected circuit elements and all the amount of voltage must be made to appear on the load for the current to be measured accurately.
Voltmeter is connected in parallel to the load due to high value of current possessed by the voltmeter. The parallel connection will cause the current flowing through the voltmeter to reduce to zero so that it won't have effect (increase) on the amount of current initially on the resistor thereby measuring the exact amount of voltage on the load.
The amplitude of the wave on the given sinusoidal wave graph is 10 cm.
<h3>
What is amplitude of wave?</h3>
The amplitude of a wave is the maximum displacement of a wave. This is the highest vertical position of the wave from the origin.
Amplitude of the wave is calculated as follows;
From the graph, the amplitude of the wave or maximum displacement of the wave is 10 cm.
Thus, the amplitude of the wave on the given sinusoidal wave graph is 10 cm.
