dedylja [7]2 years ago
3 0

Answer:

77.3W (to 3sf)

Explanation:

weight = mass × gravtaional field strength

           = 6.35kg × 10N/kg

           = 63.5N

weight = force = 63.5N

work done = force × distance

                  = 63.5N × 5.11m

                  = 324.485J

power = \frac{work done}{elapsed time}

           = \frac{324.485J}{4.2s}

           = 77.3W (to 3sf)

The amplitude, or magnitude, of a sinusoidal source is the maximum value of the source. What is the amplitude of the voltage sou
liraira [26]

Answer:

<em>A = 0.05 V</em>

Explanation:

<u>Sinusoidal Functions</u>

A sinusoid or sinusoidal function is a sine or cosine which general equation is

F(x)=A.sin(wt-\phi)

Or also

F(x)=A.cos(wt-\phi)

Where A is the amplitude or maximum value, w is the angular frequency, t is the time and \phi is the phase shift.

Comparing the given expression with the general formula

v(t)=50cos(2000t-45^o) mV

We can establish that A=50 mV = 0.05 V

A = 0.05\ V
