Answer:

when the molecules are heated , they move faster and the space between them will increase . they become very lossly packed and thus evaporate. this process can also be called evaporation in detail

when the molecules are cooled down, they move slower and they have very less space between. they becomes tight as they are cooled tgus condenses this process can also be called as condensation in detail

Answer:

When the molecules are molecules are heated the bond holding the molecules together becomes lose and hence making the molecules to vibrate and move more faster which also makes the kinetic energy to increase.

Explanation:

Answer  the gerater mass and the faster the object moves the more kenetic enegry there would be

Explanation:

Answer:

The greater the mass and acceleration the more kinetic energy there will be.

Kinetic energy and Explanation

The kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Mass and Explanation

Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies. The basic SI unit of mass is the kilogram.

Acceleration and Explanation

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer:

False

Explanation:

they are longitudinal, transverse, and surface waves

Answer:

False

Explanation:

Rather than latitudinal, it is longitudinal. So it is transverse waves, longitudinal waves, and surface waves

Explanation:

A mountain climber starts at the base of a mountain, climbs all the way to the peak, and then climbs back down to the base. At which point is the climber's potential energy the lowest  At the end of the climb.

The energy is  ability to work or produce action and / or movement and manifests itself in many different ways, such as body movement, heat, electricity, etc.

The different types of energy include Kinetic energy which is associated with the movement of bodies. Potential energy which is  stored by virtue of a body's position relative to its surface is also called gravitational potential energy.

Thermal Energy or Heat can be defined as the energy  associated with the kinetic energy of the molecules that make up an element, it can be manifested if there is a temperature difference between two bodies.

Chemical energy released or formed from chemical reactions, Solar energy from sunlight. This form of energy is used to generate electricity through photovoltaic plates.

Newton's first law states that unless acted with by an external force, the dinnerware will remain immobile. The horizontal force acting on the objects on the table in this example is the frictional force between them and the table cloth, which sets them in motion.

According to Newton's second law, the force required to accelerate the tableware is proportional to the rate of acceleration. When the tablecloth is slowly pushed, the dinnerware adjusts to fit the modest rate of acceleration and moves with it. When the tableware is pulled swiftly, it needs to accelerate at a faster pace to keep up; but, the effort required to do so is larger than the frictional force available, thus it lags behind. The tableware 'stays put' when the cloth is tugged quickly.''

This question covers one of the most enigmatic aspects of our universe! Inertia is the easy answer to your question. In other words, because of inertia, when you remove the table linen off a table full of dishes, the dishes stay put. Matter's inertia is a property that characterizes its resistance to change in motion. When you're jogging and try to turn, you'll find that the faster you go or the bigger you are, the more difficult it is to shift direction.

Other examples of inertia include the following. Another example of inertia is when you are riding in a car and the driver rounds a corner and you feel pushed toward the door or over to the driver.

The dishes' inertia comes into play when the magician removes the cloth from underneath them.

The propensity of objects to resist changes in their state of motion is known as inertia. The dishes seek to preserve their original condition of rest when the fabric is quickly pulled because of inertia.

The dishes' and the cloth's friction is insufficient to rapidly overcome this inertia. As a result, the dishes initially hold in place before friction gradually takes over and causes them to slide.

Thus, the careful balance between inertia and friction results in this seemingly supernatural effect, producing a visually stunning illusion.

Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

The energy flow in the ecosystem is important to maintain an ecological balance. The producers synthesis food by the process of photosynthesis. A part of the energy is stored within the plants. The remaining energy is utilized by the plants in their growth and development.

Answer: I'd say it's either one of these:

1. The potential energy of the water would be less at the top of the drop in river A than in river B.

2. The kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.

The energy difference between the drops in the two rivers as follows -

1 -  the kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.

2 - the kinetic energy will be less at the top of the drop in river A than in river B

The potential energy of the body at height (h) over the earth surface having mass (m) is given by -

E[P] = mgh

where -

m is the mass

g is the acceleration due to gravity

h is the height of the body

Given are two different rivers have drops that are the same height. In river A, this section of the river is a waterfall. In river B, this section has a hydroelectric dam.

Now, as the waterfalls, the potential energy of the water is converted to the kinetic energy and the lowest point of the waterfall, the kinetic energy would be maximum. Therefore, the kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.

Similarly, at the top, the kinetic energy will be less at the top of the drop in river A than in river B as the velocity of river  at that top point will be 0

Therefore, the energy difference between the drops in the two rivers as follows -

1 -  the kinetic energy of the water would be greater at the bottom of the drop in river A than in river B.

2 - the kinetic energy will be less at the top of the drop in river A than in river B

Explanation:

Since the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
