Answer:

1 / f = 1 / o + 1 / i = (i + o) / o * 1

f = o * i / (o + i) = 60 * 30 / (60 + 30) = 1800 / 90 = 20 cm

Both the object and image are in positive space for a mirror

The two forces acting on a skydiver are __________ and air _____________.
Stolb23 [73]

Answer:

Gravity and

Air resistance

Explanation:

The two forces acting on a skydiver are gravitational force and air resistance.

Gravitational force is a force that tends to pull all massive bodies towards the center of the earth. It works on all bodies that has mass. The larger or bigger the mass, the more the pull of gravity on the body.

Air resistance is the drag of air on a body as it passes to it. It is resisting force.

  • When a sky diver jumps out of a plane, he/she encounters both gravity and air resistance.
  • It soon balances both force and attain terminal velocity.
  • Air resistance is a frictional force that opposes motion.
  • This frictional force pushes in the opposite direction of motion
  • Motion direction is downward due to the celerity caused by gravity.
