How great is the air resistance that acts on a 10-N sack that falls in air at constant velocity?
constant velocity= no acceleration and no net force Assuming that there are no other forces acting on the sack (besides gravity and air resistance) this means that the force of air friction equals the weight of the object, so that the air resistance is 10N acting upward exactly balancing the force of gravity acting down

What are characteristics of fresh egg?

How can birds respire at high altitudes?
Birds have a proportionally greater surface area within the lungs for oxygen intake during flight. Birds that are frequent high-fliers also have hemoglobin with a higher oxygen affinity, allowing for better oxygen transfer. The capillaries of birds are also more efficient, keeping oxygen delivered to extremities.
