mars1129 [50]

Answer:

we know that current = charge/time

Explanation:

therefore,

A = 8000/120

A => 66.666.... amperes

An ideal transformer has 60 turns in its primary coil and 360 turns in its secondary coil. If the input rms voltage for the 60-t

notka56 [123]

Answer:

720 V

Explanation:

Given that,

The number of turns in primary coil, N₁ = 60

The number of turns in secondary coil, N₂ = 360

The input rms voltage, V₁ = 120 V

We need to find the output rms voltage of the secondary coil . The relation between number of turns in primary coil - secondary coil to the input rms voltage to the output rms voltage is given by :

$\dfrac{N_1}{N_2}=\dfrac{V_1}{V_2}\\\\V_2=\dfrac{N_2V_1}{N_2}\\\\V_2=\dfrac{360\times 120}{60}\\\\V_2=720\ V$

<h3>So, the output rms voltage of the secondary coil is 720 V. Hence, the correct option is (b).</h3>

Suppose a tidal basin is 6 m above the ocean at low tide and that the area of the basin is 5×107 m2. Estimate the gravitational

Neko [114]

Answer:

Potential energy will be $176.58\times 10^{11}j$

Explanation:

We have given the height of the basin is h = 6 m

Area of the basin $A=5\times 10^7m^2$

Volume $V=area \times height=5\times 10^7\times 6=30\times 10^7m^3$

Density $\rho =1000kg/m^3$

We know that mass is given by $m=\rho V=1000\times 30\times 10^7=3\times 10^{11}kg$

We know that potential energy is given by $E=mgh=3\times 10^{11}\times 9.81\times 6=176.58\times 10^{11}j$
