It's easy raising the barbell.
Answer:
(a) 11.8692 ohm
(b) 12.447 A
(c) 17.6 A
Explanation:
a) inductive reactance Z = L Ω
= L x 2π x F
= 45.0 x 10⁻³ x 2(3.14) x 42
= 11.8692 ohm
b) rms current
= 100 / 8.034
= 12.447 A
c) maximum current in the circuit
= I eff x rac2
= 12.447 x 1.414
= 17.6 A
Explanation:
Work done = F * d = 100N * 0.5m = 50J.
The wavelengths of terrestrial radiation from earth's surface are concentrated in thermal infrared spectrum.
<u>Explanation:</u>
The wavelengths used in thermal infrared are in the range of micrometer ranging from 8 to 15. Terrestrial radiation is defined as the radiation that is originating from earth due to radioactive materials like uranium, thorium e.t.c.
Increase in terrestrial radiation by the use of radioactive materials will consequently increase global warming as it releases green house gases thereby degrading the quality of earth's atmosphere.
