what is density
what is density
Answer:
The density of a substance is the relationship between the mass of the substance and how much space it takes up
Explanation:
thats it take my word hope thats what u meant
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Perhaps the highest density known is reached in neutron star matter. The singularity at the centre of a black hole, according to general relativity, does not have any volume, so its density is undefined.

Explanation:
F = qE
where E is an electric field.
The denser lines of electric force are, the stronger electric field will be.
Since 4 is densest part, electric force on 4 is would be greatest.
The electric field would be stronger the denser the lines with electric force are. Since part 4 is the densest, its electric force would be greatest. Therefore, the correct option is option 4.
The force acting on the items is referred to as the electric force. When two electrons and two protons are put at equal distances, the electric force that separates them is equivalent to the electrostatic charge between the two.
The electric force primarily reliant on the quantity known as electric charge rather than the object's mass. Forces involving charges are the subject of electrostatics. Static refers to charges that aren't moving, or are moving very slowly. The electric field would be stronger the denser the lines with electric force are. Since part 4 is the densest, its electric force would be greatest.
Therefore, the correct option is option 4.

Since temperature increases when the average kinetic energy of particles increases, what is happening to the added energy when the temperature remains constant while a substance is melting or boiling?.
Latent heat is the heat required to change the phase. When the temperature remains constant during melting or boiling the added energy is employed in the phase change process.
What is average kinetic energy?The average kinetic energy (KE) is defined as the one-half of the mass of each gas molecule times multiplied by the square of RMS velocity.
[tex]KE = \frac{1}{2}m (V_{rms})^{2}[/tex]
where,
KE is the kinetic energy
m is the mass of each molecule
(V)rms is the RMS velocity
As we know since the temperature is increasing the average kinetic energy of the particle increases. So the added energy is utilized in the sensible heat due to which the temperature of the body increases resulting in the increase in average kinetic energy
But when the temperature remains constant during melting or boiling the added energy is converted into latent heat energy utilized to convert the phase of a substance.

* A 5 kg ball is dropped from a height of 20 m. How much kinetic energy will it have 10 m above the ground? a. 490 J b. 392 J C. 480 J d. 100 J
Answer:
A. 490
Explanation:
soln
mass = m = 5kg
Height = h = 10m
Acceleration due to gravity = g = 9.8ms²
K.E = 1/2 × mass × (velocity)²
Recall from equations of motion
v² = u² + 2gh
Therefore,
K.E = 1/2 × mass × ( u² + 2gh)
K.E = 1/2 × 5 × ( 0² + 2×10×9.8)
K.E = 1/2 × 5 × 196
K.E = 1/2 × 980
K.E = 490 Joules
You are observing a star about 95 trillion km (10 light-years) away. How old is the most recent information you can get about this star
The most recent information you can get about this star is near 10 years old.
What is a light-year?A light-year is a distance unit, that represents the distance that light can travel in one year.
Now, we know that nothing can move faster than the speed of light, and the only information that we can get about this star comes through light (electromagnetic waves). And these waves travel at the speed of light.
So these waves would need at least 10 years to travel from the start to the satellites that can detect them, this means that the most recent information that you can get about this star is actually 10 years old.

Light travels in waves. Which of the following statements about light waves is NOT true?
A. They travel i’m straight lines.
B. they can travel through any substance
C. They can come from natural or artificial sources.
D. They change direction when they are reflected or refracted
The direction of light wave changes when they are reflected or refracted. So, all the statements are true.
What is meant by light wave ?Light waves are defined as the electromagnetic waves made of smaller, energy carrying particles called photons.
Here,
Light is an electromagnetic radiation that can have the properties of both waves and particles.
Light waves can travel in straight lines in the transparent medium like air, glass, still water, etc.
Light waves can travel through any medium or substances.
Sources of light are of two types, natural source and artificial source.
Reflection and refraction are the two properties of light.
Reflection is the phenomenon exhibited by light through which a ray of light incident on a smooth, reflecting surface, gets bounced back. Thus, during reflection, the direction of the light ray changes.
Refraction is the phenomenon by which the the speed of the light decreases when light wave travels from a lighter medium to denser medium. The light wave will bend towards the normal line. Thus, during refraction, the direction of light wave changes.
Hence,
The direction of light wave changes when they are reflected or refracted. So, all the statements are true.

Samir is watching waves hit a beach. He notices that as the waves get closer to the shore (where the water is shallow), they change direction. Which type of wave effect is he seeing?
Answer:
refraction
Explanation:
When a wave crosses a boundary between media at an angle other than normal to the boundary, it will be refracted by an amount depending on the relative speeds of the wave in the different media.
The change in direction that Samir observes is due to refraction of the wave as it slows down in shallower water.

why a bulb contains coiled wire?
Answer:
The filament is coiled to give it greater length. If the filament was just a piece of straight wire it would only give out a small amount of light. By curling the wire into a coil, a very long length of wire can be stored in a small space. When electricity flows through the coil it can give out much more light.
