In finding the distance that covers we simply add the three km which is
12 + 4 + 1 = 17km
17 km is the distance they cover.
We are going to use the displacement formula which is
d = vt + 1/2 at^2
d = 11.7 km
11.7 is the displacement
1790 = electrical energy / 2940 seconds
Electrical energy = 5262.6kJ
or
1.79kW X 49/60
= 1.46kWh
Answer:
2 x 10^14 N/Cs
Explanation:
radius, r = 3 cm
Area , A = 3.14 x 3 x 3 = 28.26 cm^2 = 28.26 x 10^-4 m^2
d = 1.1 mm = 1.1 x 10^-3 m
i = 5 A
Let time be t and electric field strength is E.
Charge, q = i x t = 5 t
q = C V
q = C x E x d
E/t = 2 x 10^14 N/Cs
Answer:
6 × 10⁻¹⁸ T
Explanation:
The magnetic flux density Ф in Weber (Wb) = BAcosθ where B = magnetic field strength and A = area in square meter,θ = angle between B and A.
Now B = Φcosθ/A
Since B = 6 × 10⁻⁶ Weber per square mega meter = 6 × 10⁻⁶ Wb/Mm² = 6 × 10⁻⁶ Wb/(10⁶ m)² = 6 × 10⁻⁶/10¹² Wb/m² = 6 × 10⁻¹⁸ Wb/m² = 6 × 10⁻¹⁸ Tesla = 6 × 10⁻¹⁸ T (Since 1 Weber/m² = 1 Tesla)
