In one experiment showing that faster-moving objects have larger masses,

A) high-velocity rifle bullets are fired at targets and their impact is measured.
B) high-speed microscopic particles pass through electromagnetic fields, and the bending of their path is measured.
C) a microscopic balance-beam is used to measure the speeds of particles emitted during radioactive decay.
D) observers move along beside high-velocity rifle bullets, in order to measure the masses of the bullets.
E) microscopic particles are released from rest in a gravitational field, and their acceleration is measured.
