I would go with c due the fact that water has tendencies to flow, meaning it will runoff and majority of the water will run off, it couldn’t be a because the fact that the grass and plant will absorb what they need. D clearly is too vague for such a question. B would be the only contesting answer but I feel c is the stronger choice because evaporations is a longer process and because of that only little amounts of water will evaporate while majority of it will become runoff due to hills, mountains, storm drains, slopes, etc.

if a laboratory balance accurately measures mass on the earth, can it accurately measure it on the moon?

SCORPION-xisa [38]

Yes, a laboratory balance can accurately measure mass on moon also.

Explanation

The work of laboratory balance is to determine the mass of an object.

Generally, a laboratory balance consists of two pans and it determines the mass of an unknown object by reference with a known mass object.

Also the mass of any object tends to remain constant in all conditions.

The mass has no effect due to gravitational force unlike weight. So the laboratory balance can work accurately in any environment as the mass will be constant in any case.

Thus, if a laboratory balance measures mass accurately on earth, then it will measure mass accurately on moon also as mass is not dependent on gravitational force.

A 50.-kilogram rock rolls off the edge of a cliff. if it is traveling at a speed of 24.2 m/s when it hits the ground, what is th

ElenaW [278]

The correct answer to the question is : 29.88 m.

EXPLANATION :

As per the question, the mass of the rock m = 50 Kg.

The rock is rolling off the edges of the cliff.

The final velocity of the rock when it hits the ground v = 24 .2 m/s.

Let the height of the cliff is h.

The potential energy gained by the rock at the top of the cliff = mgh.

Here, g is known as acceleration due to gravity, and g = $9.8\ m/s^2$

When the rock rolls off the edge of the cliff, the potential energy is converted into kinetic energy.

When the rock hits the ground, whole of its potential energy is converted into its kinetic energy.

The kinetic energy of the rock when it touches the ground is given as -

Kinetic energy K.E = $\frac{1}{2}mv^2$ .

From above we know that -

Kinetic energy at the bottom of the cliff = potential energy at a height h

$\frac{1}{2}mv^2=\ mgh$

⇒ $v^2=\ 2gh$

⇒ $h=\ \frac{v^2}{2g}$

⇒ $h=\ \frac{(24.2)^2}{2\times 9.8}$

⇒ $h=\ 29.88\ m$

Hence, the height of the cliff is 29.88 m
