Tornado would be your answer:)
A blue "H" means a center of high pressure (usually calm, sunny weather). A red "L" means low pressure (which can mean storminess). Most fronts extend from low-pressure centers.
2-slit pattern, slit spacing d, mth bright fringe: sinθ m = mλ d
Fringe position on screen at distance L: ym = L tanθ m ≅ L m( ) λ d
ym = 1.10m( ) 2λ 0.000040m → λ = ( ) 0.042m
0.000040m / 2⎡ ⋅( ) 1.10m ⎣ ⎤⎦ = 7.63×10−7 m
NOTE:tan and sin will be small angles
Question:
A wire 2.80 m in length carries a current of 5.20 A in a region where a uniform magnetic field has a magnitude of 0.430 T. Calculate the magnitude of the magnetic force on the wire assuming the following angles between the magnetic field and the current.
(a)60 (b)90 (c)120
Answer:
(a)5.42 N (b)6.26 N (c)5.42 N
Explanation:
From the question
Length of wire (L) = 2.80 m
Current in wire (I) = 5.20 A
Magnetic field (B) = 0.430 T
Angle are different in each part.
The magnetic force is given by
So from data
Now sub parts

(b)
(c)
I assume here that the engine operates following a Carnot cycle, which achieves the maximum possible efficiency.
Under this assumption, the efficiency of the engine (so, the efficiency of the Carnot cycle) is given by
where
is the cold temperature
is the hot temperature
For the engine in our problem, the cold temperature is 313 K while the hot temperature is 425 K, so the effiency of the engine is
