Answer:
a) Effective resistance when diode was forward biased = 0 Ω
b) Effective resistance when diode was reverse biased = ∞ Ω
Explanation:
Please refer attached characteristic curve for diode.
a) As per the characteristic curve, when the diode was forward biased by 0.7 Volt theoretically infinite current was flowing across the diode.
Hence effective resistance for the diode in forward biased = = 0 Ω
b) As per the characteristic curve, when the diode was reversed biased by 0.7 Volt theoretically zero (0 amp) current was flowing across the diode.
Hence effective resistance for the diode in forward biased = = ∞ Ω
Answer:
OD. The wave diffracted as it passed through the opening in the barrier.
Explanation:
A progressive wave (i.e waves in motion) has the capacity to bend around an obstacle on its path. This is one of the general properties of waves called diffraction. Others are: reflection, refraction, interference. Note that only transverse waves undergo polarization.
Diffraction of waves is the ability of waves to bend around an obstacle on its path during progression.
Thus, the bending of the part of waves as it passes through the barrier implies that the wave diffracted as it passed through the opening in the barrier.
Bruh just multiply 9.5 by 140 because if he runs for 140 seconds and runs 9.5 meters per second then he runs 9 meters per second
It is correct, the action is paddling, where you move the water backwards, and the reaction is the boat moving forwards.
Answer:
From smallest ratio to the largest ratio:
Coasting Universe - Critical Universe - Recollapsing Universe(From left to right)
Explanation:
The coasting universe is one that expands at a constant rate given by the Hubble constant throughout all of cosmic time. It has a ratio of actual density to critical density that is less than 1
The critical universe is one that is at balance with no expansion .I.e. the actual density and the critical density are equal, which makes the ratio of actual density to critical density to be equal to 1
Recollapsing Universe: The expansion of the universe reverses in the future and the universe eventually recollapses. The recollapsing universe has the ratio of the actual density to the critical density to be greater than 1
