Answer:
For the first one, its B) cities B and C
I'm not so sure, but I hope this helps.
An important aspect of fission reactions is that they produce free neutrons, which causes chain reactions.
The circuit change when the wire is added will see a short circuit occur and makes bulbs 1 and 2 turn off but keeps bulbs 3 and 4 lit. Option D. This is further explained below.
<h3>
How does the circuit change when the wire is added?</h3>
Generally, Electronic circuits consist of a series of interconnected parts that form a closed loop through which electricity may flow.
In conclusion, If two wires are linked together, a short circuit will develop, cutting power to bulbs 1 and 2. But there is no impact on bulbs 3 and 4. There is no problem with bulbs 3 and 4.

hi my name is antonette Jane S pascua please help me my question thank you for your answer
Answer:
μ ≈ 0.238
a ≈ 0.441 m/s²
Explanation:
a) F = ma (a = 0 constant velocity)
Fcosθ - μN = 0
μ = Fcosθ / N
μ = Fcosθ / (mg + Fsinθ)
μ = 310cos20 / (1120 + 310sin20)
μ = 0.2376007... ≈ 0.238
b)
Fcosθ - μN = ma
a = (Fcosθ - μN) / m
a = (Fcosθ - μ(mg - Fsinθ) / m
a = (310cos20 - 0.2376(1120 - 310sin20) / (1120/9.81)
a = 0.441308... ≈ 0.441 m/s²
