Answer:
Explanation:
A Spring stretches / compresses when force is applied on them and they are governed by the Hookes Law which states that the force required to stretch or compress a spring is directly proportional to the distance it is stretched.
F is the force applied and x is the elongation of the spring
k is the spring constant.
negative sign indicates the change in direction from equilibrium position.
In the given question, we dont have force but we know that the pan is hanging. We also know from the Newton's second law of motion that
Inserting this into Hooke's Law
computing it for x,
This is the model which will tell the length of the spring against change in the mass located in the pan.
Answer:
100 m
Explanation:
44 km/h = 12.2 m/s
110 km/h = 30.6 m/s
Given:
Δx = 16 m
v₀ = 12.2 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (12.2 m/s)² + 2a (16 m)
a = -4.67 m/s²
Given:
v₀ = 30.6 m/s
v = 0 m/s
a = -4.67 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (30.6 m/s)² + 2 (-4.67 m/s²) Δx
Δx = 100 m

Answer:
The answer to your question is KNO₃
Explanation:
Data
HNO₃
KOH
neutralization reaction
Process
1.- In a neutralization reaction an acid reacts with an alkali and the products are water and a binary or ternary salt.
Reactants acid = HNO₃ alkali = KOH
A neutralization reaction is a double displacement reaction so the salt formed is.
HNO₃ + KOH ⇒ H₂O + KNO₃
Potassium nitrate
What a sloppy question ! The purpose of a fuse or circuit breaker is to shut down the circuit when current reaches a magnitude indicating danger due to a serious malfunction. When current IS flowing in the circuit, it's always flowing at the same speed.
