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 time it will take to cook three hot dogs simultaneously is 2.5 minutes
Explanation:
Here we have, the Energy of electric heating given by Joule heating that is;
P = IV = 120×10 = 1200 J/s = 1.2 kJ/s
Since the energy required to cook one hotdog = 60.0 kJ we have
Energy required to cook three hot dogs = 3 × 60.0 kJ = 180.0 kJ
Therefore, the time required to cook the three hot dogs is
(180.0 kJ)/(1.2 kJ/s) = 150 s
The time it takes to cook three hot dogs simultaneously is
150 seconds or 150/60 minutes which is 2 minutes 30 seconds or 2.5 minutes

Answer:
Cape Point lighthouse
Explanation:
The lighthouse is located South of Cape Town, at a point where boats turn to go around the tip of Africa.
The new lighthouse has the most powerful light of all the lighthouses in South Africa, with a power of 10 megacandelas. That's why it's being visible for up to 63 km around.
It's a very important lighthouse helping to conduct the traffic around dangerous waters where 2 oceans meet.
