Answer:
d) False. If the angular momentum is zero, it implies in electro without turning, which would create a collapse towards the nucleus, so in both models the moment must be different from zero
Explanation:
Affirmations
a) true. The orbits are accurate in the Bohr model and probabilistic in quantum mechanics
b) True. If both give the same results and use the same quantum number (n)
c) True. If in angular momentum it is quantized, in the Bohr model too but it does not justify it
d) False. If the angular momentum is zero, it implies in electro without turning, which would create a collapse towards the nucleus, so in both models the moment must be different from zero

Since the velocity is constant, using Newton's First and Third Laws we know that the Friction and the Force are equal. So the friction is -12 Newtons.
Now the Normal Force (N) is also equal to the weight since the body is at a perfect balance.
So Weight is m*g = 25*10 = 250N
So N=250N
Knowing the amount of force F and the length of time t that force is applied to an object will tell you the resulting change in its momentum ΔP . This is:
F*t = ΔP
ΔP = F*t <em>but ΔP = mv</em>
mv = F*t
v = F*t/m
v = 12000 N × 5 s / 2000 kg
<h3>v = 30 m/s</h3><h2 /><h2>A/ The initial speed of the car was 30 m/s</h2>
