Current = C / seconds.

1 hour = 3600 seconds
15 minutes = 900 seconds

1 hour 15 minutes = 4500 seconds

90 C / 4500 sec = 0.02 amperes = 20 milliamperes

We calculate current from the formula:
I= \frac{q}{t} , where q is a electric charge transferred over time t 
Time should be converted to seconds:
1h 15 min= 75min= 4500s
I=\frac{90C}{4500s}=0,02A Result is in unit-Ampere

aalyn [17]

Explanation:

the weight of an object is its force exerted by gravity.

on earth we take gravitational acceleration to be 9.8 m/s^2

so the weight of an object on earth is given by F = mg

hence,

F = 90 × 9.8

F = 882 Newtons (weight on earth)

gravitational acceleration on the moon is equal to 9.8/6. so, we can just use the same formula to find the weight on the moon.

F = 90 × 9.8/6

F = 147 Newtons (weight on the moon)

make sure to ask if you need any further guidance.

The energy flow per unit time per unit area (S) of an electromagnetic wave has an average value of 440 mW/m2. The maximum value
mafiozo [28]

To solve this problem we will proceed to convert the Intensity Units given to a normal system, that is, to standardize their value. Later we will use the value of the electric field according to the RMS electric field, to find it.

Finally the magnetic field would be given based on the previously found electric field, depending on the speed of light:

The value of the intensity is:

I = 440mW/m^2 = 0.440W/m^2

The maximum value of the electric field is,

E_{max} = \sqrt{2}E_{rms}

E_{max} = \sqrt{2}\sqrt{Ic\mu_0}

Where,

I = Intensity,

\mu= Permeability constant

c = Speed of light

Replacing,

E_{max} = \sqrt{2}\sqrt{(0.440)(3*10^8)(4\pi*10^{-7})}

E_{max} = 18.2V/m

The maximum value of the magnetic field is,

B_{max} = \frac{E_{max}}{c}

B_{max} = \frac{18.2}{3*10^8}

B_{max} = 6.06*10^{-8}T

Therefore the maximum magnetic field is 7.10*10^{-8}T
