The answer is electron :)
Answer:
Oxidative phosphorylation
Explanation:
This takes place mostly in the organelle called the mitochondrion.
Oxidation of nutrients in cells by enzymes results in the release of the chemical energy present in the molecular energy.
The NADH and succinate products of the citric acid cycle are also oxidized. All this series of reactions takes place in the Electron transport system.The energy from the oxidation is used to produce adenosine triphosphate (ATP) hence the name oxidative phosphorylation.
Answer:
α = 1.875 rad/s²
t = 8 s
Explanation:
α = ω²/2θ = 15²/(2(60)) = 1.875 rad/s²
t = ω/a = 15 / 1.875 = 8 s
Answer:
c. 98 W
Explanation:
= initial power delivered by bulb at initial temperature = 40 W
= initial temperature of filament = 2000 K
Now the temperature of filament of the bulb rises
=Final power delivered by bulb at higher temperature
= Final higher temperature of filament = 2500 K
As per Stefan's law, the power delivered by the bulb depends directly on fourth power of the temperature. hence we can write
Assuming the driver starts slamming the brakes immediately, the car moves by uniformly decelerated motion, so we can use the following relationship
(1)
where
a is the deleceration
S is the distance covered after a time t
is the velocity at time t
is the initial speed of the car
The accident is 80 m ahead of the car, so the minimum deceleration required to avoid the accident is the value of a such that S=80 m and
(the car should stop exactly at S=80 m to avoid the accident). Using these data, we can solve the equation (1) to find a:
And the negative sign means it is a deceleration.
