Explanation:
Zeeman Effect -
In the presence of static magnetic field , the process of splitting of the spectral line into several components , is called Zeeman effect .
On the sun , there is a strong magnetic field , and hence , can show Zeeman effect .
And due to this ,
The sunspots can be studied by using this effect .
Sunspots are the darker region on the surface of Sun .

The Golden Gate Bridge in San Francisco has a main span of length 1.28 km, one of the longest in the world. Imagine that a steel wire with this length and a cross-sectional area of 3.10 ✕ 10^−6 m^2 is laid on the bridge deck with its ends attached to the towers of the bridge, on a summer day when the temperature of the wire is 43.0°C. When winter arrives, the towers stay the same distance apart and the bridge deck keeps the same shape as its expansion joints open. When the temperature drops to −10.0°C, what is the tension in the wire? Take Young's modulus for steel to be 20.0 ✕ 10^10 N/m^2. (Assume the coefficient of thermal expansion of steel is 11 ✕ 10−6 (°C)−1.)

An electric generator contains a coil of 140 turns of wire, each forming a rectangular loop 71.2 cm by 22.6 cm. The coil is placed entirely in a uniform magnetic field with magnitude B = 4.32 T and initially perpendicular to the coil's plane. What is in volts the maximum value of the emf produced when the loop is spun at 1120 rev/min about an axis perpendicular to the magnetic field?
b. The tubing was unable to supply any more water to the tube for use.
c. The pressure outside the tube is higher that the water pressure inside the tube.
Answers
Answer:
a. The pressure in the tubing is equal to the barometric pressure.
Explanation:
Since in the question it is mentioned that the if you take the stoppert part of the tube than the level of warer would be fall approx 4th floor and if it is continued than it wont be continue but remains constant.
Now here first we do that the tube i.e. connected to the bucket should be taken up. In the first instance, the bucket supplies the water to the tube but it would not increased far away to the level of the barometric pressure
Hence, the correct option is a.
3. Explain how the original mass of dry ice compares with the mass of carbon dioxide gas.
Answers
1. Since the solid carbon dioxide never become liquid on melting under normal pressure. Thus through the process of sublimation, the solid carbon dioxide changes to gas
2. The molecules in dry ice, are in caged like structure just as the normal water ice but as it melts, the CO2 molecules having high affinity for gaseous state converts into a gas.
3. Dry ice is heavier than its gaseous form. Density of dry ice = 97.6 lb/cu.ft.
Density of carbon dioxide gas = 0.1144 lb/cu.ft.
With higher density and a fixed volume, mass of dry ice is higher than the CO2 gas

Answer:
(a) 1.87×10⁶ V/m
(b) 1.12 mm closer
Explanation:
(a)
Electric Field = Electric potential/distance.
E = V/d ................... Equation 1
Where E = Electric Field, V = Electric potential, d = distance.
Given: V = 5575 V, d = 2.98 mm = 0.00298 m.
Substitute into equation 1
E = 5575/0.00298
E = 1.87×10⁶ V/m
(b)
without exceeding the breakdown strength,
make d the subject of equation 1
d = V/E.............. Equation 2
Given: E = 3×10⁶ V/m, V = 5575 V
Substitute into equation 2
d = 5575/3000000
d = 1.86 mm.
the plate will be = 2.98-1.86 = 1.12 mm closer
