Es

which is an example of two-dimensional motion

a bird flying in the air

a leaf falling from a tr

a train traveling along a track

d)

a lady bug crawling on a soccer ball

A leaf is falling from the tree.

Explanation:

If motion is in only one direction(x-direction) then it is know as one directional motion.

If motion is in only two direction (x and y directions) then it is know as two directional motion.

If motion is in only three direction (x , y and z directions) then it is know as three directional motion.

A bird is flying in the air -This is three directional motion.

A leaf is falling from the tree - This is two directional motion.

A train is running on track - This is  one directional motion

A lady is crawling  on the surface of the ball - This is three directional motion.

Therefore the answer is  ---

A leaf is falling from the tree.

continuous conducting path for current, power supply

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
