Answer:

gravity

Explanation:

as the earth rotates on an axis, it causes an effect known as centripetal acceleration with is an acceleration that pulls objects towards the center of the object. in planets, we call this Gravity

Answer:

See below

Explanation:

The initial downward velocity, the acceleration of gravity and air friction all play a part

What role does the somatic nervous system play?
kodGreya [7K]

Explanation:

The somatic nervous system coordinates the voluntary control of movement in the body system.

The nervous system is made up of the central nervous system and peripheral nervous system.

The peripheral nervous system is made up of the nerves that branches into the body from the spinal cord.

  • It consist of the somatic nervous system and the autonomous nervous system.
  • The somatic nervous system controls the voluntary actions of movement in the body.
  • It coordinates the reflex arc.

Two large, parallel, metal plates carry opposite charges of equal magnitude. They are separated by a distance of 40.0 mm, and th
PolarNik [594]

Answer:

Explanation:

A )

electric field E = V / d where V is potential difference between plates separated by distance d .

putting the given values

E = 370 / .040  V / m

= 9250 V / m

B )

Force on charged particle of charge q in electric field E

F = q E

F = 2.4 x 10⁻⁹ x 9250

= 22200 x 10⁻⁹

= 222 x 10⁻⁷ N .

C ) since field is uniform , force will be constant

work done by electric field putting up this force

= force x displacement

= 222 x 10⁻⁷  x 40 x 10⁻³

= 888 x 10⁻⁹ J

D )

change in potential energy

= q ( V₁ - V₂ )

= 2.40 X 10⁻⁹ x 370

= 888 x 10⁻⁹ J .

A rock is dropped from a sea cliff, and the sound of it striking the ocean in heard 3.0.s later. If the speed of sound is 340m/s
Ahat [919]

Answer:

The answer is 1020 meters.

Explanation:

The values given by the problem are:

1. T= The falling time of the rock [Seconds]

2. H=The sound velocity constant [meter/second]

The Velocity normal formula is

V=H/T

340=H/3

340*3=H

This solution considers the physic of the traveling wave sound but not really the rock falling problem, because the problem ask for the height of the cliff not even more.

Sorry about last time sorry the question is
Ivanshal [37]

Explanation:

It will increase as according to the Newton gravitational law the force of attraction is directly proportional to the product of the masses and inversely proportional to the square of the distance separating them

In case of atoms it will increase the decrease
