Answer:
3.44 W/m²
1.134 J
Explanation:
E₀ = Intensity of electric field = 50.9 V/m
I = Intensity of electromagnetic wave
Intensity of electromagnetic wave is given as
I = (0.5) ε₀ E₀² c
I = (0.5) (8.85 x 10⁻¹²) (50.9)² (3 x 10⁸)
I = 3.44 W/m²
A = Area = 0.0277 m²
t = time interval = 11.9 s
Amount of energy is given as
U = I A t
U = (3.44) (0.0277) (11.9)
U = 1.134 J
Answer:
100 times
Explanation:
Since inertia is directly proportional to the mass of an object, the higher the mass the higher the inertia. In this case, 6 Kg is 100 times heavier than 0.06 Kg to imply The bowling ball has 100 times more inertia than the tennis ball because it has 100 times more mass
Answer:
8.9m/s
Explanation:
Final velocity = initial velocity + acceleration *time
Vf=vi+at
Vf=1.4 m/s
Vi=?
A=-2.5m/s^2
T=3
1.4m/s=vi+(-2.5m/s^2)(3s)
Vi=8.9m/s
