Average intensity of electromagnetic wave is given by
I= (speed of light*permittivity*sq. electric field)/2
Speed of light = 3x10^8 m/s
Permittivity = 8.85x10^-12
Therefore,
Electric field = sqrt (2I/ (speed of light xpermittivity)) = sqrt ((2*4.50)/(3*10^8*8.85*10^-12)) = 58.22 V/m
Answer:
0.5 m/s²
Explanation:
Applying,
F = ma............... Equation 1
Where F = Force applied to the chair, m = mass of the student, a = acceleration of the chair
make a the subject of the equation
a = F/m............ Equation 2
From the question,
Given: F = 35 N, m = 70 kg
Substitute these values into equation 2
a = 35/70
a = 0.5 m/s²
Hence the new acceleration of the chair is 0.5 m/s²

Answer:
The avarage power of the body is 96.898 watts.
Explanation:
We must notice that given definition of power implies a constant consumption of energy, so that we should assume that energy consumption is constant. A Calorie is equal to 4186 joules. If we know that 
and 
, the power of body, measured in watts, is:
The avarage power of the body is 96.898 watts.
