We move a square loop of wire 2.3 cm on a side into a region of uniform magnetic field of 1.5 T with the plane of the loop perpe

vova2212 [387]

Answer:

Force will be $F=8.33\times 10^{-4}N$

Explanation:

We have given side of wire d = 2.3 cm = 0.023 m

Magnetic field B = 1.5 T

Velocity v = 2.1 m/sec

Resistance R = 3 ohm

We know that current is given by $i=\frac{Bvd}{R}=\frac{1.5\times 2.1\times 0.023}{3}=0.02415A$

Power is given by $P=i^2R=0.02415^2\times 3=0.00174watt$

We know that power is also given by $P=Fv$

So $0.00174=F\times 2.1$

$F=8.33\times 10^{-4}N$

What is the latent heat of vaporization for water

natulia [17]

When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation.

One student made the incomplete diagram shown below to represent the relationship between igneous rocks, sediments, sedimentary

Kryger [21]

Answer: Option (C)

Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.

Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
Sedimentary rocks are formed from the sedimentation and consolidation of sediments
Igneous rocks are formed due to the crystallization of magma.

Hence the correct answer is option (C)
