an oxidation reaction i think that's the answer

Explanation:

Explanation:

Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water.

Answer:

Electron, proton and neutron

Explanation:

In each and every atom they are consist of electron, proton and neutron.

Answer:

Explanation:

a=28/20

a=1.4 m/s²

V²=v0²+2a.D

28²=0+2x1.4D

784 = 2.8D

D = 280 m

Answer:

Temperature decreases as depth increases (generally)

Explanation:

In general, sunlight will heat the upper level of water.  As you go deeper into the water, the sunlight cannot reach as easily so the temperature is lower.

There are exceptions considering underwater currents like the Gulf Stream or volcanic vents.

The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.

The given parameters;

The distance traveled by each ball is calculated using the second equation of motion as shown below.

The distance traveled by the first ball is calculated as follows;

[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]

The distance traveled by the second ball is calculated as follows;

[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]

Thus, the second ball traveled a greater distance because it spent more time in motion.

2. the one that stubbed their toe

Explanation:

Answer:

Answer: Pressure is directly proportional to force and inversely proportional to area.

Explanation: Pressure is defined as the ratio of force applied to the area of cross section.

Mathematically,

P=\frac{F}{A}P=

A

F

where,

P = Pressure

F = Force applied

A = Area of cross-section

from above it is visible that pressure is directly proportional to the force applied which means that if force increases, pressure increases. It is also inversely proportional to the area of cross-section. So, when area of cross-section increases, pressure decreases.

The units of pressure are N/m^2N/m

2

and S.I. units for this term is Pascal (P).

Answer:

Let y equal lambda the wavelength of the light

e (photon) = h f = h c / y

e = 6.63E-34 * 3.0E8 / 400E-9

e = 6.63 * 3  / 400 * 10^-17

e = 4.97E-19

N= 100 J/sec/ 4.97E-19 J = 2.01E20 / sec

For harmer:-

Now

Answer:

convert 1 milligram to 1 gram:

Explanation:

1 milligram is 0.001 gram.

so... 2 milligram is 0.002

3 milligrams is 0.003

and so on.

Answer:

Explanation:

W = 25 Watts

V = 12.6 Volts

I = ? I is the current in amperes.

Solution

25 = 12.6 * I

I = 25 / 12.6

I = 1.98 amperes

V = 12.6

I = 1.98

R = ??

V = I * R

12.6 = 1.98 * R

R = 12.6 / 1.98

R = 6.35 ohms

→ Uses of Convex Mirror

• Convex mirrors are often used in the hallways of buildings including stores, schools, hospitals, hotels and apartment buildings.

• They are used in driveways, roads, and alleys to provide safety to all the bikers and motorists at curves and turns and other places where there is a lack of visibility.

• They are also used in some automated teller machines as a handy security feature that allow user to see what all is happening behind them.

• They are used in passenger side mirror on a car and somewhere it is labelled as “objects in mirror are closer than they appear” to warn the driver.

→ Uses of concave mirror :

• Head mirrors

• Shaving mirrors

• Headlights

• Ophthalmoscope (optical instrument)

• Solar furnaces

• Astronomical telescopes

In order to increase the momentum of the ball, you have to increase its speed.

The first and third choices on the list ('A' and 'C') will do that.

The factors that will increase momentum of a rolling ball are:

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

The gravitational power of the Earth ready makes the ball speed up, and in this manner pick up speed.

If you increase either mass or velocity, the momentum of the object increases proportionally.

Thus, the factors that increase the momentum of a rolling ball are

A. Moving from a flat surface to moving downhill.

C. A moving object traveling in the same direction as the ball colliding with it.

Answer:

Heat

Explanation:

Friction always slows a moving object down. ... Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.
