HELP !!!!!! An object moving forward at 10 m/s suddenly begins moving backward at 5 m/s. What is the most accurate explanation f

or this change?
The object was traveling in a straight line until it hit a brick wall and bounced backward.



The force pushing back on the object became greater than the force pushing the object forward.



The forces acting on the object were equal at first. Then the forces became unequal, causing the object to change its direction.



The forces were balanced in the forward direction. Then they became balanced in the backward direction.

What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment?
Nataly_w [17]

The glass opposite to the negative electrode started to glow. Hence, option B is correct.

<h3>What is a cathode ray tube?</h3>

A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when an electron beam strikes a phosphorescent surface.

J.J. Thomson, through his famous Cathode ray experiment, proved that all atoms contain small negatively charged particles known as electrons. In the experiment, he applied electric voltage across a cathode ray tube. a fluorescent material coating was done on the positive side. When the voltage was applied, the positive side has glowing dots.

Hence, option B is correct.

Compare and contrast physical changes with chemical changes.
Alekssandra [29.7K]

There are several differences between a physical and chemical change in matter or substances. A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
