How does Doppler ultrasound technology differ from ultrasound technology that does not use the Doppler effect? A. Doppler ultrasound is based on absorption of sound, and other ultrasound technology is based on reflection.

B. Doppler ultrasound collects data from moving objects.

C. Doppler ultrasound creates images, but other ultrasound technology does not.

D. Other ultrasound technology creates images, but Doppler ultrasound does not.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
