The correct option is A.
Fluorescent lamps have many advantages over incandescent lamps and the options given in B, C and D are part of these advantages. The option given in A is a disadvantage and not an advantage. This is because, as a result of operating at an higher temperature, it will gives out and radiate more heat.
The model bridge captures all the structural attributes of the real bridge, at a reduced scale.
Part a.
Note that volume is proportional to the cube of length. Therefore the actual bridge will have 100^3 = 10^6 times the mass of the model bridge.
Because the model bridge weighs 50 N, the real bridge weighs
(50 N)*10^6 = 50 MN.
Part b.
The model bridge matches the structural characteristics of the actual bridge.
Therefore the real bridge will not sag either.
It’s will be B because the circuit had a open or close so if that doesn’t work than it’s because it’s open
Answer:
the formulae is f = mg = vpg
Answer:
b. different types of weather occur
Explanation:
the temperture varies as one moves higher up, the higher one goes the cooler the temperature becomes. So that creates a change in weather condition.
