Magnesium Oxide Reaction
Answer:
When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).
Answer:
Mg+O2 -----MgO

a tine can collapes if all air inside it is taken out, why
When all the air inside the tin are taken out, the air outside the tin becomes greater than the air inside causing inward pushing of the tin which results in collapse of the tin.
What is unbalanced force?This is a situation when the forces acting on an object are unequal.
A tin will remain firm when air inside it is prevented from escaping. During this time, the forces of air outside the tin balances the forces of air inside the tin, this process creates equilibrium condition that cause the tin to be firm.

what can electromagnetic waves travel through that mechanical waves can not travel through?
Answer:
I believe it is vacuum of space
Explanation:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
near earth's surface is the weight of an object in newtons about 10 times it's mass in kilograms?
Answer:
Weight varies with location depending upon the acceleration due to gravity eg. for a mass m = 10kg on Earth it`s weight is W = mg = 10 x 10 = 100N.
Explanation:
Near Earth's surface, the weight of an object in newtons is 10 times its mass in kilograms. This relationship of the acceleration is due to gravity on Earth, which is 9.81 m/s².
Mathematically, it can be expressed as:
Weight (in newtons) = Mass (in kilograms) × Acceleration due to gravity
So, an object with a mass of, for example, 5 kg, its weight near the Earth's surface would be:
Weight = 5 kg × 9.81 m/s² = 49.05 N
The weight in newtons is roughly 10 times the mass in kilograms of objects near the Earth's surface. The given statement is correct.

What type of energy transformation is demonstrated in the above diagram?
A. heat energy to light energy
B. solar energy to heat energy
C. chemical energy to heat energy
D. heat energy to electrical energy
Answer:
C :)
Explanation:
Trust me
Energy transformation is demonstrated in the diagram is solar energy to heat energy.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
Solar radiation is absorbed at the surface of a receiver, which includes oris in touch with flow passageways through which a working fluid moves, during thermal conversion operations. Heat is delivered from the heating receiver to the working fluid, which might be air, water, oil, or molten salt.

when light passes through an ordinary window pane, its angle of emergence is
when light passes through an ordinary window pane, its angle of emergence is the same as its angle of incidence light refracts when traveling from air into glass because light travels slower in glass then in air
Light speeds up and changes direction when it passes through water or glass at an angle and enters the atmosphere. Turning away from the usual line, the light. Imagine a tractor transitioning from a slow-moving, muddy, grassy area to a quick-moving road.
What light passes through an ordinary window pane?Light refracts while passing from air into glass because light travels more slowly in glass than it does in air. When light passes through a typical window pane, its angle of emergence and angle of incidence are the same.
When light travels from the less dense air into the denser glass or water, what actually happens is that it slows down. The light ray also changes direction as a result of this slowing down. Refraction is brought on by a change in the speed of the light.
Therefore, When light rays bounce off a surface, transition from one transparent medium to another, or proceed through a medium whose composition is constantly changing, they change direction.

A volleyball is knocked from rest to a velocity of 22 m/s over a time of 0.2
seconds. The ball has a mass of 0.5 kilograms, What is the force applied to
the volleyball?
Answer:
[tex]\boxed {\boxed {\sf 55 \ Newtons}}[/tex]
Explanation:
We are asked to find the force applied to the volleyball. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F=ma[/tex]
We are given the mass, but we must calculate the acceleration.
1. Acceleration
Acceleration is the rate of change of velocity with respect to change. It is the change in velocity over the time.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The volleyball starts at rest or 0 meters per second and reaches a velocity of 22 meters per second in 0.2 seconds.
[tex]v_f[/tex]= 22 m/s [tex]v_i[/tex]= 0 m/s t= 0.2 sSubstitute the values into the formula.
[tex]a= \frac{ 22 \ m/s - 0 \ m/s}{0.2 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{22 \ m/s}{0.2 \ s}[/tex]
Divide.
[tex]a= 110 \ m/s^2[/tex]
2. Force
Now we know the mass and acceleration, so we can calculate the force.
[tex]F=ma[/tex]
The mass is 0.5 kilograms and the acceleration is 110 meters per second squared.
m= 0.5 kg a=110 m/s²Substitute the values into the formula.
[tex]F= 0.5 \ kg * 110 \ m/s^2[/tex]
Multiply.
[tex]F= 55 kg*m/s^2[/tex]
1 kilogram meter per second squared is equal to 1 Newton, so our answer of 55 kg*m/s² is equal to 55 Newtons.
[tex]F= 55 \ N[/tex]
55 Newtons of force are applied to the volleyball.

LA 7.0 liter balloon at room temperature (22°C) contains hydrogen gas. If the
balloon is carried outside to where the temperature is 30°C, what volume will the
balloon occupy?
Answer:
Explanation: Convert temperatures to Kelvins.
22 C = 295 K
30 C = 303 K
According to Charles' law:
V1 / T1 = V2 / T2
7 / 295 = V2 / 303
V2 = (303 * 7) / 295
V2 = 7.18983 Litres which rounds to 7.19 litres.
