Explanation:
The four things that can happen to a light wave when it hits an objects are :
1. Reflection : The bouncing back of light when the light wave strikes on a surface is called reflection of light.
2. Refraction : The bending of light when the light wave moves from one medium to another.
3. Absorption : Absorption is the process in which the light wave do not reflect back. It stays inside the material.
4. Transmission : Transmission of light is the process in which light wave goes continuously straight.
Some other process that are shown by a light wave are polarization, scattering etc.
When a light wave hits an object, it can undergo reflection, transmission, absorption, or scattering.
When a light wave hits an object, several things can happen:

Explanation: A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. The more general term for rusting and other similar processes is corrosion.
Answer:
capable of combining with oxygen and becoming iron oxide
Explanation:
From the information given, cannon ball weighs 40 kg and has a potential energy of 14000 J.
We need to find its height.
We will use the formula P.E = mgh
Therefore h = P.E / mg
where P.E is the potential energy,
m is mass in kg,
g is acceleration due to gravity (9.8 m/s²)
h is the height of the object's displacement in meters.
h = P.E. / mg
h = 14000 / 40 × 9.8
h = 14000 / 392
h = 35.7
Therefore the canon ball was 35.7 meters high.
The height of the cannon ball to have 14000 J of potential energy is approximately 357.14 meters. This is calculated using the formula for potential energy: PE = mgh, and solving for 'h'.
The potential energy (PE) of an object is given by the formula PE = mgh, where 'm' is the mass of the object, 'g' is the acceleration due to gravity (standard approximate value is 9.8 m/s² on Earth), and 'h' is the height. In your question, we want to find the height 'h'. Given that the potential energy is 14000 J and the mass of the cannon ball is 40 kg, we can rearrange the formula to solve for 'h': h = PE / (m*g).
So, inputting the given values, h = 14000 J / (40 kg * 9.8 m/s²). Solving this, we find that the height is approximately 357.14 meters. This means the cannon ball was at around this height to have 14000 J of potential energy.

The force that pushes electrons along in a circuit is called the electric field.
The force that pushes electrons along in a circuit is called the electric field. The electric field in a wire points from the higher potential end to the lower potential end and provides the force necessary to keep the electrons moving. The electrons, carrying a negative charge, move on average in the opposite direction of the electric field.

Answer: YES
Explanation:
If Tia Ana exposes her eyes to light ray in which it frequency is higher than ultraviolet ray, it may result to a gradual eyes issue such as cataracts as the radiation damages the cornea and the lens in front of the eyes.
You shot a gun straight up into the air with a velocity of 500 m/s. How long will it take beforeit hits the ground again?
You shoot a gun with a initial velocity of 500 m/s horizontally at the exact instant you drop arock from exactly the same height (at 1.6 m off of the ground). Which one will hit the ground first.
