Here's what I get

Explanation:

The hydrologic cycle describes how water moves from the surface of the Earth into the atmosphere and then returns in a continuous cycle.

I would divide it into four stages.

1. Moving from Earth's surface to the atmosphere

Evaporation: water evaporates from the surfaces of oceans and lakes. Transpiration: plants emit large quantities of water vapour through pores in their leaves.

2.Transport in the atmosphere

Condensation: The water vapour cools and condenses into clouds of water droplets or ice crystals. Winds carry the clouds around the world.

3. Moving from the atmosphere to the Earth's surface

Precipitation: The water in the clouds returns to the surface as rain, snow, or hail.

4. Transport along the Earth's surface

Runoff: Rain and melted snow flow in creeks and rivers to lakes and oceans. Percolation: Some of the precipitation moves between pores in the soil until it reaches the water table and becomes groundwater. Much of the groundwater is extracted for use as drinking water and for agricultural uses.

And the cycle repeats.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

Orque can be calculated by multiplying the force (n) applied at 90∘ to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n⋅m. if the force (at 90∘ to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?

Which of the following is a false statement about dispersion forces? view available hint(s) which of the following is a false statement about dispersion forces? dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. dispersion forces are present in all atoms and molecules. dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. dispersion forces always have a greater magnitude in molecules with a greater molar mass. dispersion force magnitude depends on the amount of surface area available for interactions.
