Answer:
20,000 N
Explanation:
First find the acceleration:
a = Δv / Δt
a = (0 − 40 m/s) / 10 s
a = -4 m/s²
Next use Newton's second law to find the force on the car:
F = ma
F = (5000 kg) (-4 m/s²)
F = -20,000 N
According to Newton's third law, the force on the wall is equal and opposite the force on the car.
F = 20,000 N
No because people change mentally over time. They could let some problems go or could develop others
Answer:
I = 12 A
Explanation:
For this exercise we use the relationship that voltage is proportional to the product of current and resistance
V = I R
I = V / R
let's calculate
I = 120/10
I = 12 A
fusion is when solid changes it's state to liquid
and vaporization is when liquid changes it's state to gas
so the difference between fusion and vaporization is the state
Answer:
Noise in the environment
Electrons emitted via the photoelectric effect
Explanation:
Physical entropy can be seen as a disorderliness that can be observed in a physical system. The noise in a physical system can be used for secure number generation because of its randomness.
Noise is known to have no defined pattern and hence, can be used to creates secure random key generations.
Electrons emitted via the photoelectric effect: Electrons are emitted in a random order whenever a beam of light is incident on a photoelectric material. These electrons emitted can be used for random key generations
