Answer:

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.

A group of physics students hypothesize that for an experiment they are performing, the speed of an object sliding down an incli

goblinko [34]

Answer:

v = 2.974

Explanation:

Perhaps the formula should be

v = √(2*g*d (sin(θ) - uk*cos(θ) ) This is a bit easier to read.

v = √(2* 9.80*0.725(0.707 - 0.12*0.707) ) Substitute values. Find 2*g*d

v = √14.21 * (0.707 - 0.0849) Figure out Sin(θ) - uk cos(θ)

v = √14.21 * (0.6222)

v = √8.8422 Take the square root of the value

v = 2.974

A child is holding a wagon from rolling straight back down in a driveway that inclined at 20 degree horizontal. if the wagon wei

Digiron [165]

Answer:

F = 51.3°

Explanation:

The component of weight parallel to the inclined plane must be responsible for the rolling back motion of the car. Hence, the force required to be applied by the child must also be equal to that component of weight:

$F = Parallel\ Component\ of\ Weight\ of\ Wagon= WSin\theta\\$

where,

W = Weight of Wagon = 150 N

θ = Angle of Inclinition = 20°

Therefore,

$F = (150\ N)Sin\ 20^o$

A wire carries a 2a current. what is the current in a second wire that delivers twice as much charge in the same amount of time?

Soloha48 [4]

Answer:

Explanation:

Current is charge per time. So if the second wire delivers twice as much charge in the same amount of time, it must have twice the current.

2 × 2A = 4A
