Answer:
The correct option is "In order to gain more power you would need to increase either current or voltage."
Explanation:
To answer the question, we note that;
The formula for Electrical Power are as follows,
P = I²·R, or P = I·V,
Therefore, if we increase either the current, I with the voltage, V remaining constant or we increase the Voltage, V with the current, I remaining constant or we increase both the voltage, V an the current, I the Power, P will be increased.
Therefore, the correct option is "In order to gain more power you would need to increase either current or voltage."
Answer:
n = 1000 pulses
Explanation:
Given that,
The frequency of a pulse waveform, 
To find,
The number of pulses counted during 100 ms.
Solution,
The frequency of a pulse waveform is equal to the number of pulses per unit time. It is given by :
n = 1000 pulses
So, there are 1000 pulses counted in a pulse waveform.

E) 7.46m
F) it shows the back of her hand.
Explanation:
Detailed explanation is shown in the illustrative diagram below.
Answer:
2.83×10⁻¹¹ N.
Explanation:
From the question,
Using
F = qvB....................... Equation 1
Where F = magnetic force acting on the duck, q = charge of the duck, v = velocity of the duck, B = magnetic field of the duck.
Given: q = 6.47×10⁻⁸ C, B = 4.09×10⁻⁵ T, v = 10.7 m/s.
Substitute these values into equation 1
F = 6.47×10⁻⁸×4.09×10⁻⁵×10.7
F = 2.83×10⁻¹¹ N.
Hence the magnetic force acting on the duck is 2.83×10⁻¹¹ N.
