After rock y is released from rest several seconds after rock x is released from rest, what happens to the separation distance s

between the rocks as they fall but before they reach the ground, and why? take the positive direction to be downward.

's' increases at all times that Rock X falls since Rock X falls with a greater velocity than Rock Y.

<h3>What is a frictional force?</h3>

The friction force is the opposite force generated when two parts slide over each other if the air is passing over the rocks the frictional force would be the drag force.

Given: Frictional forces are considered to be negligible.

A few seconds after Rock X is released from rest, Rock Y is also released. Consider moving downward to be constructive. Both rocks are launched from rest, thus their initial velocities are equal to zero (u = 0).

We know that the velocity is given by,

v² = u² + 2as

Rock X is released first, followed by Rock Y, and because Rock X travels faster than Rock Y, it travels farther. This is due to the fact that whenever Rock X has already acquired some velocity (t).

Its velocity (v) is higher, increasing the spacing (s). In conclusion, because Rock X falls faster than Rock Y,'s' rises each time Rock X hits the ground.

The complete question is given below:-

Rock X is released from rest at the top of a cliff that is on Earth. A short time later, Rock Y is released from rest from the same location as Rock X. Both rocks fall for several seconds before landing on the ground directly below the cliff. Frictional forces are considered to be negligible. After Rock Y is released from rest several seconds after Rock X is released from rest, what happens to the separation distance S between the rocks as they fall but before they reach the ground, and why? Take the positive direction to be downward.

A skull believed to belong to an ancient human being has a carbon-14 decay rate of 5.4 disintegrations per minute per gram of ca
larisa86 [58]

Answer:

9.43*10^3 year

Explanation:

For this question, we ought to remember, or know that the half life of carbon 14 is 5730, and that would be vital in completing the calculation

To start with, we use the formula

t(half) = In 2/k,

if we make k the subject of formula, we have

k = in 2/t(half), now we substitute for the values

k = in 2 / 5730

k = 1.21*10^-4 yr^-1

In(A/A•) = -kt, on rearranging, we find out that

t = -1/k * In(A/A•)

The next step is to substitite the values for each into the equation, giving us

t = -1/1.21*10^-4 * In(5.4/15.3)

t = -1/1.21*10^-4 * -1.1041

t = 0.943*10^4 year

lions [1.4K]

Answer:

B. Chemical changes involve the formation of a new substance.

Explanation:

They can both release energy, both can be measured, and chemical changes can be caused by oxygen, so I believe it would be B.

Why does the sun have less gravitational pull on planet far away like Pluto?
blondinia [14]

Answer:

Because the planet is far away from the sun

Explanation:

The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.

While, over here the Pluto is very far away from the Sun so it will have very little gravitational  pull and still keeps revolving around the Sun
