Answer

6.9 x 10¹²Hz

Explanation:

Given parameters:

Wavelength of the wave  = 4.35 x 10⁻⁵m

Unknown:

Frequency of the wave = ?

Solution:

The speed of a wave is related to the wavelength and frequency using the expression below;

          C  = Fλ

C is the speed of light = 3 x 10⁸m/s

F is the frequency

λ  is the wavelength

Insert the given parameters and solve;

      3 x 10⁸  = F x 4.35 x 10⁻⁵

         F  = \frac{3 x 10^{8} }{4.35 x 10^{-5} }   = 6.9 x 10¹²Hz

tino4ka555 [31]

Answer:

Q = 16163.88 Joules

Explanation:

Given the following data;

Initial temperature, T1 = -25°C

Final temperature, T2 = 150°C

Mass = 45.5 g

Specific heat capacity of ice = 2.03 J/g°C

To find the quantity of heat required;

Heat capacity is given by the formula;

Q = mcdt

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

dt = T2 - T1

dt = 150 - (-25)

dt = 150 + 25

dt = 175°C

Substituting into the formula, we have;

Q = 45.5 * 2.03 * 175

Q = 16163.88 Joules
