Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:
330 m/s approx
Explanation:
The RMS speed of a gas is proportional to square root of its absolute temperature is
V ( RMS ) ∝ √T
Here V₁ = 200 , T₁ = 23 +273 = 300K , T₂ = 227 +273 = 500 K
Putting the values
200 / V₂ =
V₂ = 330 m/s approx
Bohr's model of the atom shows that electrons follow a definite orbit with distinct distances away from the nucleus. The electron cloud on the other hand suggests that the electrons are within a cloud without a definite orbit. The locations of electrons are based on probability that they are there.
