Answer:
120 miles
Explanation:
Speed = distance traveled/ time taken.
Distance traveled = speed * time taken
Speed = 40 miles per hour, time = 3 hours.
Distance = 40*3
The train's traveled distance is 120 miles.
Answer:
In these formulas, it is useful to understand which variables are parameters that specify the nature of the wave. The variables E₀ and B₀ are the amplitudes of the electric and magnetic fields.
Explanation:
Generally, the variables that specify the nature of the wave are:
(1) The amplitude of the electric field, designated as E₀, and
(2) The amplitude of the electric field, designated as B₀.
90t - .100 = 75t
90t - 75t = 0.100
15t = 0.100
t = 0.0067
<u>t = 0.0067 hours or 24.12 seconds</u> (.0067 * 60 minutes * 60 seconds)
(i)1.5cm
(ii)4.5cm
(iii)10cm
