Speed =
150 km = 150 000 m
Speed =
Speed = 20.83 m/s, or 75.0 km/h
Answer:
True
Explanation:
It is a true statement as the motor transforms the electrical energy given to it into mechanical energy. When electrical energy in forms of current and voltage is given to motor then its shaft rotate and torque produced and mechanical energy obtained.
Similarly in case of generator when we move its prim mover by any mechanical means then electrical energy is produced
So this is a true statement
E.S.D. (Electrostatic discharge) is the sudden spurts of electricity between two or more electrically charged objects. So that build up of static electricity can be formed by tribocharging, or rubbing the two objects together really fast. so the answer is static.
Answer:304 not 261
Explanation:
That is, in prototype form anyway – the custom Chiron Longtail hit 304 mph (490 km/h) last year, but the production version dubbed the Chiron Super Sport 300+ will be electronically limited to only 273 mph (440 km/h).

Answer:
Explanation:
We shall use Ampere's circuital law to find magnetic field at required point.
The point is outside the circumference of two given wires so whole current will be accounted for .
Ampere's circuital law
B = ∫ Bdl = μ₀ I
line integral will be over circular path of radius r = 41 cm .
Total current I = 5A -3A = 2A .
∫ Bdl = μ₀ I
2π r B = μ₀ I
2π x .41 B = 4π x 10⁻⁷ x 2
B = 2 x 10⁻⁷ x 2 / .41
= 9.75 x 10⁻⁷ T . It will be along - ve Y - direction.
