Which of the following types of rocks could contain organic matter?

Answer:

(c) 400j

Explanation:

The amount of energy dedicated to kinetic energy will be 400 J.Option C is correct.

The energy possessed by the body by the virtue of motion is known as kinetic energy. It is found as the product of mass and the square of the velocity.

Part of the energy in each machine that exists dissipates to the medium in the form of heat, friction with the surface, and other forms of energy dissipation.

If the entire kinetic energy loses 200 J in the form of heat and 200 J in the form of friction this quantity of energy has been wasted and cannot be utilized as kinetic energy.

The energy goes toward kinetic energy will be ;

Kinetic energy = Electric energy -Heat-friction

Kinetic energy = 800-200-200

Kinetic energy =400 J

Hence, the amount of energy dedicated to kinetic energy will be 400 J.Option C is correct.

Answer:

The correct answer is C: Disposal of radioactive waste.

Explanation:

During nuclear fission reactions, many intermediate radioisotopes are produced. For example, uranium releases different mass distribution isotopes and these isotopes emit radiations.

Most harmful isotopes for the environment are strontium and cesium because these have half-lives and an inclination of mixing in food chains.

When radioactive wastes are removed from nuclear reactors they flow towards the swimming pool and also have the tendency to isolate the short-lived isotopes from the environment.

Therefore, radioactive waste disposal has always remained a major problem

Answer:

The third one is the correct answer:)

Explanation:

Answer:

it travels at a different refractive index.

Explanation:

for example when light travels into water, it slows down, causing it to continue to travel at a different or another angle or direction. hope this helped!

Refraction of light occurs due to the different refractive indices of the medium in which the light travels.

Explanation:

The medium through which the light travels have different refractive indices, because of which the light rays crosses the boundary of the refractive indices. They are shifted from the travelling line according to the refractive index of the medium and hence, refraction is seen.

For example, air is medium with less refractive index as compared to glass, and therefore the light ray when enters into glass, travels slow and refracted from the actual path towards the normal of the ray.

Answer:

d = 10.076 m

Explanation:

We need to obtain the velocity of the ball in the y direction

Vy  = 24.5m/s * sin(35) = 14.053 m/s

To obtain the distance, we use the formula

vf^2 = v0^2 -2*g*d

but vf = 0

d = -vo^2/2g

d = (14.053)^2/2*(9.8) = 10.076 m

Answer:

8,790.9

Explanation:

first we start with parentheses so we take (102,900/12) and (170x1.27) and simplify these 102,900/12 would equal 8575, and 170.1.27 would equal 215.9. next we add these together, so (8575)+(215.9), and that would equal our answer which is 8,790.9

To calculate (102,900/12)+(170x1.27) correctly to significant figures, we find that the sum is 119.9 when rounded to the tenths place. It's essential to respect the rules for significant figures, where the precision of the least precise measurement used in the calculation dictates the precision of the final answer.

The solution to the problem (102,900/12)+(170x1.27) needs to be expressed to the correct number of significant figures. When performing calculations with measured values, it's important to consider the precision of the numbers involved. In addition, different operations have different rules for significant figures.

After calculating each component, we then add the two results. The sum must be reported to the lowest place value of the least precise measurement (in this case, the tenths place). This means that the correct final answer, expressed with the appropriate number of significant figures, is 119.9 (assuming the first calculation to be an exact number).

When dealing with the addition of 89.332 and 1.1, since the second number has fewer significant figures after the decimal place, the result should be reported to match that precision. The answer, when rounded to the correct number of significant figures, is 90.4.

Overall, understanding the rules for significant figures is crucial in accurately reporting measurements and results in scientific and mathematical contexts.

Answer:

solids have definite shape and volume, liquids have definite volume, but no definite shape, gas has no definite shape or volume. I hope that this is what you was looking for.

Answer:

Solids

Gases

Liquids

Explanation:

Solids have the strongest inter-molecular forces in them, this causes them to have a definite shape and volume.

Gases have the weakest inter-molecular forces in them, this causes them not to have a definite volume or shape. Moreover gases are compressible which means with enough pressure the volume may change for the same number of particles.

Liquids have weaker inter-molecular forces than solids but stronger than gases, this causes them to have a definite volume, but indefinite shape.

1.1 A. An electric oven with a resistance of 201Ω and a voltage of 220V drwa a current of 1.1 A.

The easiest way to solve this problem is using the Ohm's Law I = V/R.

An electric oven has R = 201Ω, and a drop of voltage V = 220v, solve using I = V/R:

I = 220V / 201Ω

I = 1.09 A ≅ 1.1 A

In the eighteenth century Isaac Newton found out that when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors. He named this phenomenom as dispersion of light.

This phenomenom occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.

The color appears as cyan when an object reflects green and blue light.

Answer: A

Explanation

The light that is visible to the eye is a form of electromagnetic energy.

White light consists of the electromagnetic spectrum combined by lights of various wavelengths.

Each individual light in this white light has distinct frequency and wavelength.

The clouts observed is due to the reflection of light consisting of three colors- red, blue and green known as primary additive colors of light.

When blue and green combine, primary subtractive color forms, cyan.

Answer:

centripetal force

Explanation:

When a person spins a bucket of water in a circle, the force acting on the bucket to keep the water inside is called centripetal force.

The centripetal force is a constant resultant force that acts on an object in circular motion.

Answer:

centripetal force

Explanation:

Answer:

In Physics, the desire of an object to keep doing what it is doing is termed as Inertia.

Explanation:

Inertia is the quality of an object due to which it does nothing or remains unchanged.

According to Newton's first law of motion "An object at rest remains at rest or keeps moving in a straight line with uniform speed unless an external force is acted upon it."

This law is also known as the Law of Inertia.

Well let's analyse.

First we know Ohm's law of resistance that states:

[tex]R=\dfrac{U}{I}[/tex]

Where R is resistance, U is voltage and I is current.

If we express current we get:

[tex]I=\dfrac{U}{R}[/tex]

Because resistance cannot be equal to 0 (violation of mathematical law) the only thing that may cause current being zero is voltage.

Which means that as long as your voltage is bigger than 0V then there will be current (if we are talking about AC).

So to answer the question: Electric current is caused by voltage and regulated by resistance.

Hope this helps.

A standard for comparison that helps to ensure that the experimental result is caused by the condition being tested is the 'control'.

Explanation:

Control is the standard used for the comparison which helps to make sure that the results of a certain experiment are caused by the condition which is being tested.

In controlled experiments, only one variable is changed at a time while the other variable (controlled variable) is kept same in order to isolate the results.

Answer:

Explanation:

We are given that an object that weighing 75 N is pulled on a horizontal surface by a horizontal pull of 50 N to the right with 30 N friction to the left.

We are to find the acceleration of the object.

Mass = 75/10 = 7.5 kg

Acceleration = Net Force / mass

Net force = Horizontal force - Frictional force = 50 - 30 = 20

Acceleration of the object = 20 / 7.5 = 2.67 N/kg

Answer:

[tex]2.61m/s^2[/tex]

Explanation:

We first of all find the net force F acting on the object. The frictional force [tex]F_f[/tex] and the pulling force [tex]F_p[/tex] act in opposite directions. Hence the net force is given as follows;

[tex]F=F_p-F_f...............(1)\\Given;\\F_p=50N\\F_f=30N\\Hence;\\F=50-30\\F=20N[/tex]

It is this net force that brings about the acceleration of the body. Recall that

[tex]F=ma..............(2)[/tex]

where m is the mass of the object and a is the acceleration.

The weight W of the object is given, hence we obtain its mass as follows;

[tex]W=mg..............(3)[/tex]

where g is acceleration due to gravity taken as [tex]9.8m/s^2[/tex].

Given;

W = 75N

[tex]75=m*9.8\\m=\frac{75}{9.8}\\m=7.65kg[/tex]

From equation (2), we have

[tex]a=\frac{F}{m}..................(4)[/tex]

Hence;

[tex]a=\frac{20}{7.65}\\a=2.61m/s^2[/tex]

Final answer:

Chemical reactions involve the conversion of thermodynamic energy and kinetic energy. Thermodynamic energy changes determine if a reaction is exothermic or endothermic, while kinetic energy is needed to overcome activation energy. Potential energy stored in chemical bonds is often converted into other forms like mechanical kinetic energy.

Explanation:

Chemical reactions always involve changes in energy. There are two main types of energy relevant to reactions: thermodynamic energy and kinetic energy. Thermodynamic energy is related to the energy changes when reactants convert to products, which can be either released or absorbed. This type of energy change defines whether a reaction is exothermic or endothermic. Kinetic energy, on the other hand, is the energy that reacting molecules must possess to overcome the energy barrier to react and form products, known as the activation energy.

In the course of a reaction, chemical bonds break and new ones form. The energy stored in these bonds is a form of potential energy. When substances convert, there is a conversion of energy forms - for example, chemical potential energy can be converted to mechanical kinetic energy, such as in a car engine where the combustion of gasoline moves pistons.
