Answer:

The correct answer is combustibility

Explanation:

A chemical property of a matter is a property in which a matter has the tendency to change its form through chemical reaction(s).

A matter is said to have combustibility property if it can undergo combustion. Combustion is a chemical process in which a substance burns in excess oxygen to produce carbon dioxide and water.

Consider the equation below

CH₄ + O₂ ⇒ CO₂ + H₂O

The equation above shows methane burning in excess oxygen to produce carbon dioxide and water

What are the basic si units for the wavelength of light?

noname [10]

Answer:

Meter (m)

Explanation:

The wavelenght of a light wave is a measure of the distance between two successive crests (or two successive troughs) of a light wave.

Since the SI units for the distance is the meter (m), then the SI unit for the wavelength is also the meter (m).

Wavelength is related to the frequency of the light wave by:

$\lambda=\frac{c}{f}$

where

c is the speed of light

f is the frequency of the light

Sunlight, with an intensity of 667 W / m², strikes a flat collecting surface perpendicularly and is totally absorbed. The area o

alexandr1967 [171]

Answer:

F = 20.07 μN

Explanation:

given,

intensity of sunlight = 667 W/m²

area of surface = 9.03 m²

speed of light = 3 x 10⁸ m/s

force = ?

we know

force = $intensity \times \dfrac{Area}{speed of light}$

force = $667 \times \dfrac{9.03}{3\times 10^8}$

F = 20.07 x 10⁻⁶ N

F = 20.07 μN
