What is the speed of light

Answers

Answer 1

Answer:
In vacuum and empty space, it's 299,792,458 meters per second
(186,282.4 miles per second).

In any material stuff, it's somewhat less. How much less depends on
what stuff it is ... it's different in each material "medium".

Which describes an image that can be produced by a concave lens?The image is real and smaller than the object.
The image is virtual and larger than the object.
The image is virtual and smaller than the object.
The image is real and larger than the object.

Answers

Answer:

The image is virtual and smaller than the object.

Explanation:

A concave lens is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its center than at its edges.

It always produces virtual images because the image appears to form on the same side of the lens where the object is placed.

The image is always smaller than the object. Far the object, smaller will be its image.

A light ray diagram of a concave lens is attached for a better understanding.

Answer: The image is virtual and smaller than the object.

A kitten has a mass of 0.8 kg. It is moving forward with a momentum of 0.5 kg • m/s. What is the kitten’s velocity?

Answers

The kitten's velocity is V=0.625 m/s

Explanation:

Solving the problem,

Given

Mass=0.8 kg

Momentum=0.5 kg.m/s

Velocity=?

We have the formula,

P=M*V

V=P/M

V=0.5 kg.m/s/0.8 kg

V=0.625 m/s

The kitten's velocity is V=0.625 m/s

When Jackson throws a tennis ball in a straight path, what two forces cause the ball to eventually stop moving?

Answers

After Jackson lets go of the ball, there are two forces on it
that influence what it's going to do. They are gravity and
air resistance.

Air resistance is just plain friction. As long as the ball continues
to move through air, it loses kinetic energy to the air and gradually
slows down.

While the ball is in the air, there are no other forces on it that cause
it to stop moving.

If you absolutely must have another one, it doesn't occur until the
ball hits the ground. But that isn't even another force. It's just more
friction, from scraping against concrete and grass.

Gravity pulls the ball down to the ground. But gravity doesn't make
the ball stop moving. In fact, gravity tries to make it move faster and
faster, and gravity would succeed if it weren't for all the friction that
the ball encounters.

Well, the force that originally caused it to start moving was inertia, but the forces that cause it to stop are friction and gravity. Gravity pulls the object towards the center of the Earth, causing it to slow and eventually stop, and friction is the resistance between the ball and the ground (or whatever).

Hope this helps!

Definition of transalatory motion

Answers

Translational motion is the motion by which a body shifts from one point in space to another. One example of translational motion is the the motion of a bullet fired from a gun. An object has a rectilinear motion when it moves along a straight line. Hope this helps! :)

Answer:

Translational motion is the motion of body where body moves in the linear path. It is the motion in which all points of a moving body move uniformly in the same line or direction.

Which phrase describes an atom?

Answers

You haven't included the list of choices that goes with the question, so it's
impossible for me to choose the correct one, or to help you choose it.

Regarding my ability to answer the question and collect the 5-point bounty,
I'm free to make up any phrase of my own that correctly describes an atom.

-- very very very very very very very tiny

-- includes even tinier particles, with electric charges
both positive and negative

-- smaller than the wavelength of visible light

How is a positive charge usually given to a neutral object?

Answers

the answer is 1) neutrons are added to the object.
