Answer:

Depends.

Explanation:

It may be a bit harder because of the path's winding direction, but like the other question I answered, direction does not matter when calculating speed. So, you should be able to determine the speed using the formula per normal.

That is, if this path has railing of some form.

If not, then this answer is almost impossible.

No. Quite literally, it will be impossible, if not very difficult, to calculate an accurate speed.

(speed = distance ÷ time)

Hope this helped!

Water pressure in a lake is greater __________. a. at the bottom b. at the surface c. at any point, for pressure is the same d.

sweet-ann [11.9K]

Answer:

The correct answer a

Explanation:

In the fluid pressure is a measure of force per unit area, in this case force is the weight of the fluid that increases as we descend. Therefore, the pressure increases with the depth of the fluid.

A cue ball, moving with 9.0 N·s of momentum strikes the nine-ball at rest. The nine-ball moves off with 2.0 N·s in the original

lisov135 [29]

Answer:

P = 7.28 N.s

Explanation:

given,

initial momentum of cue ball in x- direction,P₁ = 9 N.s

momentum of nine ball in x- direction, P₂ = 2 N.s

momentum in perpendicular direction i.e. y - direction,P'₂ = 2 N.s

momentum of the cue after collision = ?

using conservation of momentum

in x- direction

P₁ + p = x + P₂

p is the initial momentum of the nine balls which is equal to zero.

9 + 0 = x + 2

x = 7 N.s

momentum in x-direction.

equating along y-direction

P'₁ + p = y + P'₂

0 + 0 = y + 2

y = -2 N.s

the momentum of the cue ball after collision is equal to resultant of the momentum .

$P = \sqrt{x^2+y^2}$

$P = \sqrt{7^2+(-2)^2}$

P = 7.28 N.s

the momentum of the cue ball after collision is equal to P = 7.28 N.s
