Find the volume of a sphere if the diameter has the length $12 \mathrm{~cm}$. Use $\pi \approx 3.14$.

A 1.0-m-long segment of wire lies along the x-axis and carries a current of 2.0 A in the positive x-direction. Around the wire is the magnetic field of $( 3.0 \hat { \mathbf { i } } \times 4.0 \hat { \mathbf { k } } ) \times 10 ^ { - 3 } \mathrm { T }$. Find the magnetic force on this segment.

Find the volume and surface area of a right circular cylinder with a diameter of 200 centimeters and a height of 100 centimeters.

A Pb wire that is tightly wound around a solenoid with a diameter of  $4.0 \mathrm{~mm}$ is cooled to  $5.0 \mathrm{~K}$. The wire, a  $50-\Omega$ resistor, and a variable emf source are all linked in series. What value does the emf have when the emf increases if the wire's superconductivity is lost?

A straight wire segment of length 0.60 m carries a current of 18.0 A and is immersed in a uniform external magnetic field of magnitude 0.20 T. (a) What is the magnitude of the maximum possible magnetic force on the wire segment? (b) Explain why the given information enables you to calculate only the maximum possible force.

Why does the fact that tungsten wire has a high melting point make it useful in the filaments of lightbulbs?

When who and whom are used in adjective clauses, which modify nouns, the correct form is determined by the use of the word in the clause. Who is used for subjects and subject complements. Whom is used for objects of verbs or prepositions.\Subject in Clause: What passing-bells for these $\underline{\text{who die as cattle}}$?\Direct Object in Clause: A dust $\underline{\text{whom England bore}}$,...\Practice In your notebook, correctly complete given sentence with who or whom. Then, identify the pronoun's function in the clause.
"Brooke, (whom, who) wrote "The Soldier," died before seeing battle".

A hanging titanium wire with diameter 2 mm (2 $\times 10^{-3}$ m) is initially 3 m long. When a 5 kg mass is hung from it, the wire stretches an amount 0.4035 mm, and when a 10 kg mass is hung from it, the wire stretches an amount 0.807 mm. A mole of titanium has a mass of 48 grams, and its density is 4.51$\mathrm{~grams/cm^3}$ . Find the approximate value of the effective spring stiffness of the interatomic force, and explain your analysis.

If the perimeter of this square is 40 centimelers, then (a) what is the diameter of the circle? (b) what is the circumference of the circle? (Use $3.14$ for $\pi$.)
