an ice cube is placed in the sun later there is a puddle of water later still the.puddle is gone what kind of change has occured

TiliK225 [7]

Clear question is;

An ice cube is placed in the sun. Later there is a puddle of water. Later still the puddle is gone. What kind of change has occurred?

Answer:

Physical change.

Explanation:

There are two type of changes called physical change and chemical change.

In Physical changes, there is only change in the appearance of the substance and not its chemical composition. Whereas, in Chemical changes the substance changes entirely into another substance with a new chemical formula.

Now, for the ice cube, it has melted from a solid state to a liquid state. Thus, there is only a change in appearance and not its chemical composition. Thus, it's a physical change that has occurred.

A bird carries a 25 g oyster to a height of 11m what is the gravitational potential energy of the oyster

garik1379 [7]

Given data:

Mass of oyster (m) = 25 g,

= 0.025 kg ( since 1 Kg = 1000 g)

Height of oyster (h) = 11 m,

determine gravitational potential energy (GPE) = ?

Gravitational potential energy is energy of an object possesses because of its position on the earth. The amount of gravitational potential energy of an object on earth depends on its mass and height from the earth.

Mathematically,

GPE = m. g. h Joules

Where,

GPE = gravitational potential energy,

m = mass of object in Kg,

g = gravitational force in m/s², g = 9.8 m/s²

h = height of the object in meters,

Now substituting all the values in the equation GPE

GPE = 0.025 Kg × 9.8 m/s² × 11 m

= 2.695 J

Gravitational potential energy of the oyster is 2.695 J

You are conducting an experiment inside a train car that may move along level rail tracks. A load is hung from the ceiling on a

The train is not an inertial frame of reference, and the train may be moving at a constant speed in a straight line or the train may be instantaneously at rest.

<h3>What is uniform speed and Acceleration?</h3>

The pace at which an object's position changes about relation to a frame of reference and time is known as its velocity.

Uniform velocity is the state in which a body travels the same distance in the same amount of time. When the amplitude and direction of a body's average velocity (v) over time (t) do not change over time, the body is said to be moving at a uniform velocity. An illustration of uniform motion is the moon's orbit around the earth.

As the rate of change of velocity, acceleration is an illustration of a vector quantity.

When an item is moving in a straight path with an increase in velocity occurring at regular intervals of time, it is said to be experiencing uniform acceleration. The uniform acceleration of an object during free fall is one example.
