Answer: D) subatomic, atomic, and nanometer-size systems.
Explanation: Quantum mechanics applies to subatomic, atomic, and nanometer-size systems.
Answer:
It will emerge at its initial speed not a slower speed.
Explanation:
It will emerge at the initial speed because the medium at the point of emergence is the same as the medium before incidence.
Light moves at a constant speed in any particular medium. Hence, the speed of light in air is constant in air and the speed of light in glass is constant in glass.
Answer:
Power = 56.25 W
Explanation:
Power = workdone/time taken
We are given;
Mass; m = 50 kg
Final velocity; v = 3 m/s
Time; t = 4 s
Workdone = ½mv² = 1/2 × 50 × 3²
W = 25 × 9
W = 225 J
Thus;
Power = 225/4
Power = 56.25 W
Answer:
<h2>9.5 kg</h2>
Explanation:
The mass of the bowling ball can be found by using the formula
p is the momentum
v is the velocity
From the question we have
We have the final answer as
<h3>9.5 kg</h3>
