Bullet of mass embeds itself in a

wooden block with mass which then compresses a spring by a distance

before coming to rest. the coefficient of kinetic friction

between the block and table is (a) what is the

initial velocity (assumed horizontal) of the bullet? (b) what

fraction of the bullet’s initial kinetic energy is dissipated

(in damage to the wooden block, rising temperature, etc.)

in the collision between the bullet and the block?

Why there is no inductive reactance in dc circuits

The ph is the a.independent variable b.the dependent variable c.control group

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
