Because you can die from the hurricane that’s why it is dangerous
Answer:The Poynting vector SS represents the flow of energy in an EM field. Specifically, if uu is the energy density of the field, the Poynting vector satisfies the continuity equation for it:
∂u∂t+∇⋅S=0
∂u∂t+∇⋅S=0
in vacuum. (This is Poynting's theorem.)
In your particular problem, EE and BB are perpendicular and their cross product is proportional to the product of their amplitudes. Thus
Sz=cμ0B2.
Sz=cμ0B2.
You then have to use your knowledge of BB to work out SS.
Explanation:
Velocity = displacement / time
Displacement = 2.3 km
Time = 5.78 mins
Velocity = 2.3/5.78
Velocity = 0.398 to the nearest 3 significant figures
Answer:
velocity of the car is 7.3516 m/s
Explanation:
M1v1a + m2v1b = m1v2a + m2v2b
775*30 + 1475*0 = 775*v2a+1475*11.9
Let v2a be x
23250 + 0 = 775x + 17552.5
775x = 23250-17552.5
775x = 5697.5
X = 7.3516 m/s
