A(n) 8.2 g bullet is fired into a(n)82. g block of wood at rest on a horizontal surface and stays inside. After impact, the block slides 11 m before coming to rest . The acceleration of gravity is 9.8 m/s ^ 2 . If the coefficient of friction between the and the block is 0.5, find the speed of he bullet before impact .

Which statement correctly describes the relationship between frequency and wavelength?

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
