hi have a nice day

will be less than 26 °C as water has a relatively higher specific heat than sand.

Explanation:

The specific heat of a substance is the amount of heat energy absorbed by one unit of mass of the substance when its temperature increases one unit.

From that, you can derive the equation for the specific heat of a substance:

specific heat = heat / (mass × ΔT)

Thus, assuming that all the heat provided by the lamp to both samples is the same and, as given, the amount (mass) of both samples is also the same, you have that the specific heat of the samples will be:

specific heat = constant / ΔT

So, specific heat and ΔT are inversely related.

It is known that water has a higher specific heat than sand (that is why the sand on the shore of a beach is, during the day, hotter than the water and your feet get burned when you walk on a sandy beach on a sunny day

What is the ph of with a 4.6 x 10-6 M hydroxide ion concentration?
nlexa [21]
<h3>Answer:</h3>

pH = 8.66

<h3>Explanation:</h3>
  • The pH refers to the acidity or alkalinity of a solution.
  • It is calculated by getting the negative logarithm of Hydrogen ions concentration.
  • pH=-log[H⁺]

In this case;

we are given [OH⁻] as 4.6 x 10^-6 M

We are required to calculate the pH

We need to know that;

pH + pOH = 14

pOH = -log[OH⁻]

To get the pH we can calculate the pOH first,

pOH = -log[4.6 x 10^-6 M]

        = 5.34

but, pH + pOH = 14

Therefore, pH = 14 - pOH

                        = 14 - 5.34

                        = 8.66

Therefore, the pH of the solution is 8.66

(a) Red light has a wavelength of roughly 700 nm. What is the wavelength in m? ball park 10.10' (b) What is the wavelength of re
joja [24]

Explanation:

1)

a) Wavelength of red light = 700 nm

1 nanometer = 10^{-9} meter

Wavelength of red light in meter will be:

=700 nm=700\times 10^{-9} m=7.00\times 10^{-7} m

b) Wavelength of red light = 7.00\times 10^{-7} m

1 meter  = 39.3701 inches

Wavelength of red light in inches will be:

7.00\times 10^{-7} m=7.00\times 10^{-7}\times 39.3701 inches

=2.7559\times 10^{-5} inches

2)

Value of distance given = 90.123 km

1 km = 3280.84 feet

90.123 km=90.123 \times 3280.84 feet=295,679.1433 feet

1 foot = 0.1515152 chain

295,679.1433 feet=295,679.1433\times 0.1515152 chain

=44,799.88453 feet\approx 4.48\times 10^4 chains

Value of distance in chains:

90.123 km=4.48\times 10^4 chains

Tienen capacidad de fijar enerjgia luminosa utilizando agua y co2 para transformarlo en carbohidratos
Cloud [144]

Answer:

las plantas

Explanation:

Las plantas son los seres vivos capaces de transformar energía luminosa utilizando agua y dióxido de carbono (CO₂) en energía química en forma de moléculas llamadas carbohidratos. El proceso a través del cual realizan esto se denomina fotosíntesis, y para ello requieren un pigmento de color verde denominado clorofila, el cual es necesario para captar la energía luminosa proveniente del Sol.
