A teacher pushes on a wall with a force of 125N but the wall does not move. Calculate the amount of work in Joules the teacher accomplished.

Answer:

Unlike genetic changes, epigenetic changes are reversible and do not ... DNA methylation works by adding a chemical group to DNA. ... Non-coding RNA may also recruit proteins to modify histones to turn genes “on” or “off.” ...

Explanation:

Answer: 0.5 HZ

Explanation: Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there is 1 cycle per 2 seconds. So the frequency is 1 cycles/2 s

Answer:

It's C

Explanation:

Mechanical vibrations of sound conductance qualify sound waves as mechanical waves. ( I hope that made sense but I know it's C. If ot's wrong please tell me)

Answer:

The same height above sea level.

Explanation:

The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.

The mutual force of gravitational attraction between the sun and each object does that.

This is all it takes, which is lucky because this is all there is.

Answer:

Radiation is the emission or transmission of energy in the form of waves.

Explanation:

.

Radiation is the transmission of energy. Radiation is formed in waves that can travel through space and through material.  

Answer:

Each object exerts a force on the other, and the two forces are equal and in opposite directions

Hope this helped!

Answer:

I got an idea.

This will be a story. (comic can also be done with this. In fact it is better)

The title is the journey of the ice cube. (change it if you want)

Main character - ice cube

There was an ice cube made by the water from the freezer in an ice shop.

The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.

That is the end.

You can add, edit or even not consider this one. But this is just an example to spark up your ideas. Sorry if I made some English mistakes.

Hope that it helped

Answer:

46,502,000 times

Explanation:

The question asked how many times back and forth, so you divide by 2 (so in half); and if it's 93,004,000 then you divide that by 2 which equals, 46,502,000.

Answer:

false

Explanation:

Understand Newton’s first law of motion. Experience suggests that an object at rest will remain at rest if left alone, and that an object in motion tends to slow down and stop unless some effort is made to keep it moving. An object will go on forever if there were no forces to act upon it. In space, a rocket will go forever at the speed it projects.

Answer:

The human body affects vision and bone density in space.

Explanation:

Answer:

From the information I have gathered I believe your answer is C a solution containing an ionic compound.

Explanation:

Charge is supplied with energy in the internal circuit and the energy is transformed into other forms in the external circuit. G. The location on an electric circuit where the charge possesses the greatest amount of electric potential energy is the + terminal of the battery. Which of the following statements are true about an electric circuit? A series circuits are characterized by the fact that there is a single pathway by which charge can travel from the + terminal to the - terminal. B. During any single loop of charge around a series circuit, the charge will pass through each resistor in the circuit.

Answer:

No, the sound produced by screeching brakes is not a useful form of energy, because it does not contribute to stopping the car.
